Though it was Jill who had set off running with Sparrow, Mina and the ginger-haired woman were following close behind. Sparrow found it very easy to cast her shield spell in a flat disc behind the two, and bring it forward to scoop up them and Jill altogether, so that they could all fly forward faster than running, the dark openings of other offices rushing by them as they hurtled down the passage.

They also nearly hurtled off the disc as Sparrow desperately tried to halt at a T-intersection. It was only Jill’s strong grip that kept them on. "Maybe don’t go that fast," she grumbled, as she hauled everyone back from the edge.

"All of our loved ones are heading straight into mortal danger," said Sparrow. "And you want me to go slow?"

"I wish you had asked me that question before you gallivanted down to London," muttered Jill.

"A smooth approach is faster than a rough one," whispered Mina, "even if it seems slower."

"If it’s any consolation," said the ginger-haired woman, "it’s not like we have no idea which way the library is." She pointed to a sign on the wall that had a left-pointing arrow, above which was written Central Library. "It’s only the bureaucracy that’s a maze, not the building itself."

"See there?" said Jill. "You can go a bit more slowly and smoothly."

Yet as Sparrow turned the disc to the left and set off once more, she barely slowed down, preferring to keep an eye up ahead and come to more gradual stops. She did breathe a bit easier now that she could tell the actual way to the library – a bit. Her heart still hammered in her chest and her thoughts internally beat her over the head for letting her own family, birth and acquired alike, go in the worst possible direction.

And then her heart nearly flew out of her chest as she heard the distant echoes of a wolf’s howl. The disc flickered, threatening to dump everyone out onto the tiles at a dangerous speed. In her panic she sped up again, forcing the disc to fly down the corridors at such speed that momentum made everyone lurch forward and sideways and back with one turn and another. Sparrow was moving so quickly that she missed the sign twice, having to double back to take the correct way, spurring her to move even faster.

"You know it occurs to me," said Jill, as the wind whipped her hair about, "that if Jocasta had chosen to go slow and smooth, she could be leading us to the library, instead of disappearing on us."

"Ask her where she is then," grumbled Sparrow. "My head’s kind of busy." The library was coming up close now, just down a pitch-dark corridor. Sparrow flew straight into it, counting on the glow of her disc to light the way, counting on the strength of her shield to charge through all defenses –

Far into the darkness she saw a flicker of light. Suddenly a hand was twisting her ear, and in the distraction of her pain Sparrow lost concentration on her spell, throwing everyone out onto the tiles, at a speed even greater than she had feared. She was only saved from her own injuries by Jill wrapping her in a fierce embrace just before they struck the floor, so that Jill took the brunt of the blows as they rolled. Sparrow was spared, but Mina was not, and the woman’s cries of pain echoed off the walls.

From the distance where the light had flickered, there came a gruff voice. "Who’s that then? Who’s there?"

From right next to Sparrow, there came a sound like someone trying to speak through a hand over their mouth. Sparrow struggled out of Jill’s arms and peered into the gloom where she thought Mina might be. Yes, there was the shape she’d been in just before – and there was the ginger-haired woman with a hand over Mina’s mouth. Before Sparrow could say anything, Jill was crouching over her protectively. In a voice as deadly as it was quiet, she growled, "Do we have a traitor in our midst?"

The ginger-haired woman made no reply, but pointed her wand up the corridor. She took her other hand away from Mina and put a finger to her lips, before nodding to where she was pointing.

"Whassat?" said the gruff voice. A little light flickered into existence, showing a wand, held by a gnarled hand, emerging from the sleeve of a dark robe, worn by a grey-bearded man. The man squinted right at the spot where Jill crouched over Sparrow. "Someone here? Something fishy going on around here."

Next to him another little light appeared, at the end of the wand of a fresh-faced young fellow, also clad in dark robes. "There was that fly that buzzed right over my head earlier. I told you that didn’t make sense."

"Better tell the boss then," said the old man, turning back up the corridor.

"I’m not doing it," said the young fellow. "I’ve got all my life to live, right? Got that plot of London picked out, I have."

The old man chuckled. "And I’ve got nothing left to lose. I’ll do it."

So the two of them departed, their little lights bobbing away through the darkness.

When the lights could no longer be seen, Sparrow whispered, "Were you the one who twisted my ear?"

The ginger-haired woman nodded.

"So you screw us over one moment and then –"

"Ssh." The woman fished in her pocket and brought out a golden ring. She held it out to Jill. "Take this. You’ll find out what it does quickly. I’m going to try to get the Wireless. Don’t wait for me." With that, she sprang to her feet and vanished into the darkness.

Sparrow shook her head, crawling out from under Jill and stiffly rising. "Dammit," she whispered, "who the bloody hell was that?"

"Ruby," whispered Mina. "Ruby Lupin. She’s been useful. Even I wasn’t able to get my hands on Wren’s ring, once Dolph took it. Jill, put that thing on and take Sparrow’s hand, we’re going to be tricking our way past the outer defenses."

"Tricking?" whispered Sparrow. "We can’t just skulk our way around, we have to get to my family as quickly as possible! I was intending to charge right through before someone distracted me." She glared at the spot where she had last seen Ruby. "I am not in a mood to waste time."

"And I told you," growled Mina, "that a smooth approach is faster than a rough one."

"I don’t know if we can take a smooth approach from this point forward," whispered Jill. "Unless we smooth-talk our way past these people. But Sparrow and I are way too visible, we couldn’t get within a country mile of them before they started blasting. We might need to start blasting our way forward from here."

"We’re going to be taking advantage of your visibility," whispered Mina. "Or Sparrow’s, at least. As for you, just put the ring on."

"But –"

"Hang on," said Sparrow. "I finally have a moment to breathe, let me try to contact Jo." She closed her eyes, and concentrated on her thoughts of Jocasta. In a moment, the image of a little green dot moving erratically appeared in her mind – then in the next moment, it was gone, and sight slammed back into Sparrow’s eyes. She shook her head. "Dammit. Jill, ask Jocasta where she is."

Jill grumbled and closed her eyes. In a moment she opened them again. "Still with Miranda and the gang, and the Jones family, making their way in further. Quietly. I was explicitly instructed not to loudly barge in and screw this all up."

"Stealth mission after all," whispered Sparrow. "Get the ring on."

Jill looked wary, as she rose to her feet. She slipped the ring on and vanished. "Oh!" she cried, her voice echoing just a little too loud for Sparrow’s comfort. "Sorry," she whispered. "How well is this working?"

Sparrow peered at the space where Jill had been. There was yet a faint outline of a great tall teenage witch there, even more visible when she moved, thought it be as faint as shifting on her feet. "I think the ring is low on power."

"Let’s be moving then," said Mina. "Follow my lead and do as I say, and we’ll get through this."

Sparrow felt a great hand closing over hers, and then she was being led forward into the darkness.

Sadly the plan involved Jill being at a distance from Sparrow, and it was Mina who was leading Sparrow by the hand. Up the hallway, Sparrow had been able to reach out to Jill’s outline and brush her arm for comfort, but as they rounded a bend, Jill suddenly fell back, just out of Sparrow’s reach.

For in the deep blue hue of the hallway’s bend, in a dimness born of the reflection of distant light, were silhouetted many figures. The plan was now in motion. Mina’s form was now that of a large man, and with a great and rough hand, she dragged Sparrow forward. With a gravelly voice, she growled, "No worries, lads, I’ve finally got her. The Wolf will want to see her. Make a hole, I’ve got to get through double-quick."

Ten little lights flickered into existence, at the end of ten wands, and ten wizards were revealed, as much as their dark clSmith allowed. One old jowled fellow looked delighted. "Excellent, good man, excellent! I shall inform the Wolf of the good news myself."

As the man was turning to go, and everyone else’s eyes were fixated on the highly-visible prize, the mostly-invisible Jill slipped behind them.

Sparrow’s shield spell threw a golden light over the hallway as it sprang into existence, for a wizard had come flying at her, hurled like the rest of his fellows by a concussive force. He slammed into the golden barrier and slid to the ground, as the remaining wizards skidded forward, all of them emitting cries of pain. Sparrow dismissed the shield and immediately began casting body-bind and silencing spells, her frantic motions missing the last one, nearly allowing him to reach his wand, before Mina succeeded in binding him.

Sparrow rounded on Jill’s outline, intent on scolding her, but when Jill took the ring off Sparrow could see the shame in her eyes. Mina was stepping forward, as if to scold Jill in turn, but Sparrow put a hand on the girl’s shoulder. "It’s fine," she whispered. "We can just switch places and Jill can be the distraction. She’s a much bigger prize anyway."

Jill chuckled. "You know it, you love it. Alright." She handed the ring to Sparrow, and the three of them made their way forward, further around the bend.

The hallway ended in a staircase, down which a blue light was spilling. The library was close now. But there was another set of silhouetted figures standing well before it. As Sparrow slipped on the ring, Mina ducked behind Jill and whipped out her wand, pointing it at Jill’s back and saying in a gruff but quite tone, "Right, prisoner, keep marching. Oi, you lot, make a hole, I’m bringing the ringleader to the Wolf."

"Smith!" exclaimed one of the figures. "How in the name of Merlin did you manage to capture Jillian Patil all by yourself?"

"He ought to be a rump roast right now," said another figure.

"This is a bit dodgy," said a third figure.

Before Mina could explain herself, Sparrow had already stolen behind the figures and started casting the body-bind spell. One by one they started falling – yet not silently, for as their bodies made soft thumps against the tile, some grunted in pain. The few remaining who were free whipped around at the sound. Sparrow switched to casting a silencing charm on them, only to realize that this still left their hands free, and they were pointing their wands in her general direction – she ducked, letting jets of light shoot over head and go pinging off the walls.

In a trice Mina had cast the body-bind spell upon them all, and switched to silencing charms without missing a beat. But suddenly from the hallway’s end, there came the steady beat of feet tramping down the stairs, and the steady clack-clack of high heels among them. "Shit," muttered Sparrow, before clapping a hand over her mouth and scampering into the shadows.

"Two groups have just missed their check-ins," said a cold female voice. "Something is going on here."

Sparrow could now see the voice’s source – a witch not robed in black, but draped in it. A sleek black dress with a slit up the side, sleek black hair framing a bone-pale face, a black cape spilling down her back. About her stood many tens of black-robed figures. "Smith, what is this?"

"Lady Carrow," said Mina, "I have just captured –"

But as Lady Carrow’s face scanned the scene further, her expression changed from bewilderment to horror and betrayal. "Traitor!" She had her wand out faster than blinking, casting a jet of light straight at Mina, who only managed to dodge it by shifting her shape to someone much shorter. Carrow’s next spell came as quick as the first, directed at Mina’s feet, and the girl was only saved by Sparrow reflexively casting a shield spell.

The impact of the light upon the glowing barrier was nearly as strong as Sparrow had experienced from an enraged Jill. She stumbled, and gasped. Heads swiveled to her location. She tried to shrink back further into shadow, but the glow from her shield spell was dispelling all shadows. Jets of light flew in her direction. She shifted the glowing barrier to herself.

Just in time, for Lady Carrow was throwing curses her way. One and another they struck, hard enough to force Sparrow a step back. A quarter of the robed figures were hurling curses alongside Carrow, keeping up a barrage that prevented Sparrow from dropping the shield even a moment. This was not even like resisting Jill; Jill’s whirling fire had not been directed. Losing the shield here would not be like throwing open the door of a blast furnace, it would be like jumping in front of the Hogwarts Express.

The remainder of the robed figures were directing their fire at Jill and Mina, and laying down covering fire between them and Sparrow, effectively cutting them off. Lady Carrow let up her barrage against Sparrow’s shield, but directed her fire at the ceiling, blasting chunks out of it to fall onto Sparrow’s head. Sparrow was forced to extend her barrier to cover her head, and now she was holding up the weight of a ton of stone as well as resisting enemy fire. Unsettling memories of a nearly-fatal afternoon flashed into Sparrow’s mind. Who was here to save her now?

She instinctively looked to Jill, who was busy blocking and returning fire, as Mina was ducking out from behind her to cast her own spells. Once more she tried to Send to Jill, a desperate plea for aid – yet she could not hear her own thoughts echoing. Jill was not even looking her way.

Except – wait – there was Jill, glancing at her, eyes flashing red, just a moment, before she had to turn her gaze back to the fight. And what answered Sparrow’s vain hope was not words, but an image that flashed before her eyes. Great boulders rolling down upon a gaggle of screaming people. Sparrow mentally kicked herself for not thinking of it sooner. She altered her shield spell to tilt the stones forward, rolling them right onto her attackers. Some of them screamed, some of them managed to deflect a few stones, some of them were struck down. The majority were forced to jump back, into the obscurity of a great cloud of dust. For a moment, the pressure on Sparrow’s shield was released. She had a chance. She let the spell go, dashing over to Jill –

A jet of purple light shot out of the dust cloud. Sparrow’s back erupted in pain. Then in her knees, when she hit the stones. She was saved from tumbling further forward by brawny arms – not Jill’s, as she looked up, but those of Mina’s current form.

And Jill – Sparrow could see a red glow filling the room. Jill stood before her, her aura glowing bright. A great rumbling growl echoed off the walls.

Out of the swirl of dust stepped Lady Carrow. Behind her stood many dark-robed figures, more than Sparrow had seen Lady Carrow enter the hallway with. Sparrow pointed her wand at them, casting her shield spell in a wall of golden light that filled the hallway from floor to ceiling – but it flickered. Between concentration and pain, the pain was winning out.

†††† SPARROW. IT'S ALRIGHT. YOU CAN DROP YOUR SHIELD. ††††

The warm relief of hearing Jill’s voice within her head again warred with the chilling dread of what the girl meant. Frantically Sparrow tried to Send back. Oh God, Jill, no, not again –

A high, cold laugh erupted from Lady Carrow. "This is your vaunted power? This is the threat against us? Absolutely pathetic. A few choice memory charms, and we’ll have you two working ever so willingly for me."

Perhaps there would have been nothing, after all, to stop the vast blast of fire that roared from Jill’s mouth. Nothing to save the dark-robed figures from being driven backward or engulfed in flame. Or both, for as the last bits of flame flickered out, Sparrow could just see some of them that had stumbled backward over each other, and flames were still licking at their robes where they lay.

Sparrow tried to start forward, desperate to at least put the flames out. A spasm of pain shot through her back. She found herself collapsing into Mina’s arms again.

Only Lady Carrow stood firm, her wand raised. She spared a brief and disdainful glance at the fallen. "Slightly useful to me," she sniffed, "for cannon fodder if nothing else. But something tells me, given all I’ve heard of your exploits this evening, Miss Patil, that you have reached the end of your energy. And now it is my turn." She grinned, pointing her wand directly at Jill.

Only to stiffen in shock, for out of the air behind her had just appeared a raven-haired girl, casting a spell directly at her neck. As Lady Carrow dropped, Jocasta disappeared with a small thump of air.

And then there was another thump, and there was a hand on the small of Sparrow’s back. Sparrow found herself breathing deeply for the first time in minutes as her muscles unclenched and the fire faded. "Goddamn," she breathed, "you really don’t hate me."

"I will say I am extremely annoyed," whispered Jocasta. "I explicitly told you to be quiet so you didn’t cock it all up. And now – " There was the howl of a wolf, unsettlingly close, as well as the sound of many tramping feet. "Now we will have to be very stealthy, to get you the bloody hell out of this hallway. I will not permit you to object to the method."

"What do you – "

Sparrow felt a cold splash on the back of her neck, a chill that caused her to arch with pain. The next moment was a confusing blur, for Sparrow could swear she was continuing to arch back and back and back, as if twisting around herself, tighter and tighter – yet it was all of a moment, and in the next moment, her vision exploded into thousands of bold fragments, and she could feel the slightest brush of air over every single bit of herself, stirring as two vast conglomerations of color fragments shifted in her sight. One of them was quite a bit redder than the other. Potential food? Yet it did not smell quite like food, it smelled like smoke.

And there was the greatest group of color fragments, bright blue. Light. Light meant exit. Exit meant open air. Air. Sparrow needed air. And there was a rich musky scent coming from that same direction – wolf scent. Wolf kill meant lots of food.

Sparrow shot towards the light.
