"Can't see how to turn it on," Ravel said.

Ghastly stepped out before Ravel hit something he wasn't supposed to. "Let's leave that to the scientists, OK? We'd probably break it if we tried."

"I'm sure we could figure it out," Ravel said, peering at it. "We're intelligent enough. We may not be scientist-smart, but we're smart in other ways. We're street-smart, is what we are."

"And what street is that, exactly?"

Ravel shrugged. "Probably one of the dumber ones, to be honest. Maybe you're right. We'll tell Skulduggery we found it, and Lament can come over and get it working."

"That's a really good idea, Grand Mage."

"I sometimes have them."

They left the Accelerator and retraced their steps, eventually finding their way back to a corridor they recognised. It was cold and damp and the lights flickered overhead. They passed a corner that should have been guarded by a Cleaver. There was no Cleaver there now. Ghastly checked his watch. Early shift-change, maybe although he wasn't aware of any Cleaver who'd ever left his post unguarded in their entire history.

Three mages hurried their way. Ghastly didn't know any of them particularly well. Brennock was the big one, and the woman was Paloma. Tevhan, the third, was the strong, silent type that liked to glower at everyone.

"Grand Mage," said Brennock, "Elder Bespoke. I'm sorry to interrupt, but there is an emergency call from Detective Pleasant."

Ravel quickened his pace. "What happened? What's wrong?"

"I'm afraid I don't know, Grand Mage. He will only talk to you."

Brennock and Paloma fell in on either side of Ravel, and Tevhan waited on Ghastly to catch up. All three of them Roarhaven mages. Ghastly took out the map as he walked, scanning the fine print until he found the names of the sorcerers who'd been assigned to draw it up. He found them, and nodded to Tevhan as he passed. Three names. Brennock, Paloma and Tevhan.

"Grand Mage," Ghastly said, as he put the map away, "did you know that the sparrow flies south for winter?"

"What an odd thing to say," Ravel said, and as he turned, he snapped his palm against the air and Paloma slammed into the wall.

Ghastly spun, catching Tevhan with a right cross that buckled his knees, making him drop the knife he was sliding from his sleeve. Ghastly hit him again, and again, never giving him a chance to get his bearings. Tevhan was an Adept, but Ghastly didn't know what discipline he'd trained in. He wasn't going to take any chances.

When Tevhan went down, Ghastly turned back to Ravel in time to see him sweep Brennock's legs from under him. Brennock's head smacked into the ground and Ravel gave him an extra kick to make him stay there.

"What do you know," Ravel said, breathing a little faster, "Skulduggery's silly little code actually works."

ament showed them to a small room with four large sigils engraved on the walls. He left them and Valkyrie stood beside Skulduggery in the centre of the room. After a moment, the sigils started to glow, and hazy images of Ravel and Ghastly appeared before them.

"Sorry for the extra trouble," Ghastly said, "but we needed to talk to you over a secure line, as it were." His image was transparent but he sounded like he was actually standing right there in front of them.

"I should get this for my phone," Valkyrie said.

"Trouble with the Supreme Council?" Skulduggery asked.

"No, actually," said Ravel. "Well, yes, but this isn't because of them. We found the Accelerator. It's in good condition but it doesn't work."

"Don't worry about that," Skulduggery said. "Lament is confident he can get it running. What's the other problem?"

"We were attacked," Ghastly said. "Roarhaven mages. People who have been working beside us for the last year. We've managed to keep it quiet so far. Our own people trying to kill us is not something we want to explain to Strom and the others right now."

"So far, our would-be assassins haven't given us any answers," Ravel said. "Our Sensitives have tried breaking through but they know how to block psychic probes."

"Do you think they attacked because of the Accelerator?" Skulduggery asked. "How did they even find out you were looking for it?"

Ghastly glanced at Ravel, who chewed his lip. Eventually he said, "We think our phones have been tapped. And that's not the only problem. It seems that every Cleaver in that area had been reassigned minutes before, to give our attackers a clear chance. We've talked to a few people and no one can explain to us how this happened."

"I can," said Valkyrie. "It was Madame Mist."

"We don't know that," Ravel said quickly. "And even if she had wanted to kill us, this is much too clumsy for someone like her."

"She might be getting desperate," said Skulduggery. "If she already knew about the Accelerator's existence, then she wouldn't have wanted you stumbling upon it."

"And if she didn't know of its existence?"

"If she just found out about it by listening in to our conversation, then she may have simply seen her chance and latched on to it, however clumsily."

"Maybe," Ravel said. "But I'm still not convinced."

"Even so, an attempt on your lives is a major step for anyone to take. If they've gone this far, they'll go further."

"We need greater control over the Cleavers," Ghastly said. "They don't question orders. If Mist or whoever used them against us once, she might do so again, and I don't fancy going up against those scythes."

"Agreed," said Skulduggery. "Erskine, you should take direct control from now on the Cleavers take orders from the Grand Mage and that's it. Mist has Roarhaven on her side. We need the Cleavers on ours."

"But their numbers are still depleted," Ravel pointed out. "If Mist is behind this and we go up against her, even with the Cleavers and whatever mages are loyal to us, we can't be guaranteed of winning. We need more. We need an advantage."

All three fell silent. None of them wanted to state the obvious.

"We could ask the Supreme Council for help," Valkyrie said.

"Let's change the subject before I hit someone," Ghastly said, and Ravel's image immediately shifted away from him slightly. "What do we need to do to get this Accelerator working?"

"Lament will have to take a look at it," Skulduggery said. "Can you get it shipped up here?"

Ravel shook his head. "It can't be moved. From what we understand, the Sanctuary itself acts as a kind of lightning rod. If you want to use it to power Argeddion's cage, you're going to have to bring the cage to Roarhaven."

"OK," said Skulduggery, "it shouldn't take too much convincing to get Lament to agree to that. I also think Valkyrie's ex-boyfriend will come in handy here."

Ravel frowned. "The dead vampire?"

Valkyrie glared at him. "I think he means Fletcher."

"Oh. Sorry."

"Caelan was never my boyfriend."

"I didn't mean to-"

"We don't talk about Caelan," Ghastly muttered.

"I'm really sorry, Valkyrie," Ravel said. "Fletcher's great. He's wonderful. I'm sure he'd be delighted to help, and having a Teleporter here will certainly solve some problems. We'll arrange that, we'll get him over to you, start the ball rolling, as it were. Once again, sorry about bringing up the vampire."

Ghastly shot him a look, whispered, "Why do you keep talking about him?"

"I can't help it," Ravel whispered back. "Now he's all I can think about."

"You realise," Valkyrie said, "that we can hear you both perfectly well."

Ghastly shut up immediately. Ravel nodded slowly. "Right. Righto. You sure you heard everything, now? Did you hear the bit where I complimented you and called you amazing?"

"I must have missed that part."

"Oh, that's a shame. That's a real..." He looked off to his right, eyebrows raising. "What's that? I'm needed elsewhere? Important business?"

Ghastly sighed. "There's no one there."

"Valkyrie, Skulduggery, we'll talk with Fletcher and get back to you," Ravel said, and glared at Ghastly as their images faded to nothing.

Four hours later, the same huge plane that had flown them to Switzerland appeared as a speck over the mountains. Valkyrie held fire in her hand to warm herself while she waited. She knew Fletcher wasn't onboard. He rarely suffered through the indignities of travel any more. Because Teleporters can only teleport to places they've already been, or places they can actually see, he had devised a tactic to be used on planes and trains and boats.

First, he'd have teleported to Ireland, where he'd have introduced himself to the pilots and stepped on to the plane. Then he'd have teleported home to Australia and spent the next few hours doing whatever it was he did when he was over there. When the plane had reached its destination roughly where it was now the pilot would call him and he'd teleport back to the plane, look out of the window, see her, and teleport down. It was a simple and effective way of visiting places all around the world without having to actually waste time getting there. And it was typical Fletcher.

The plane got closer and she took off her mask, then sent a fistful of shadows curling along the snow to attract their attention. A moment later, Fletcher Renn appeared in front of her.

"Oh my God!" was the first thing he said. "It's freezing!"

Valkyrie grinned. "That'd be all the snow. Come on, it's warmer inside."

He frowned at the hole in the rocks she'd squirmed through to get out there. "Haven't these people heard of doors?"

"It keeps the Abominable Snowmen out."

He stared. "Seriously?"

"Two of them, yeah. One of them tried to eat my head."

He held out his hand and she took it, and he crouched down, peered through the gap, and suddenly they were on the other side of the rocks, in the warmth. These days, teleportation didn't even result in a twinge of nausea, much less puking her guts up like it did in the early days. Fletcher straightened, and smiled at her.

"Hi," he said.

"Hi." She smiled. "You look well." He did. She'd forgotten how cute he was. "Your hair's still stupid."

Fletcher nodded. "Thanks for that. Should've known better than to expect you to stay nice for more than a few seconds."

She laughed. "Sorry. Bad habit. You really do look good, though. Australia agrees with you."

"Australia has good taste. And it's taken a while but you've obviously decided that you can't live without me, either. I have to say, coming up with this whole Argeddion thing just to have an excuse to see me again? I admit it, I'm flattered."

"You're such a goon. Why do you have to be such a goon? You're cute and you're hot and if you'd just stay quiet, you'd be perfect."

He shrugged. "My mouth gets me into trouble. As you well know."

"And now you're a dope. You're both a goon and a dope. Well done."

"I try my very best." He suddenly frowned. "Should we hug, or something? I think we should hug, after not seeing each other for so long."

"Why not?" she said, and hugged him. For a moment Valkyrie remembered how good it felt, and then she stepped away.

His eyes flickered over her shoulder, and he stood a little straighter as Skulduggery walked up.

"Skulduggery."

"Fletcher."

Fletcher stuck out his hand. Skulduggery observed it for a moment.

"I'm sorry, what are we doing now?"

"Shaking hands," Fletcher said. "Like adults. I just want you to know that this past year has changed me. I've grown, as a person. I'm not the same Fletcher you used to know."

"You look a lot like him."

"Well, yeah, but-"

"And you have the same ridiculous hair."

"Can we just shake hands?"

"Of course we can," Skulduggery said, and they shook. "Now what?"

"I, uh... I don't really know. What do adults usually do after they shake hands?"

"Generally, the first thing they do is let go."

"Oh, right," Fletcher said, and Skulduggery took his hand back. "So, Skulduggery, how've you been? You're looking well. That's a really nice tie."

"It's blue."

"And such a nice shade."

Skulduggery looked at Valkyrie. "You promised me he wouldn't be annoying."

She glared. "And you promised you wouldn't be mean."

Skulduggery sighed, turned back. "Fletcher, how is your training progressing? As the last Teleporter, it's important that you take your responsibilities seriously."

"I am," Fletcher said. "I do."

"When I was your age, I met the last Kineticist. Do you know what that is? He had the ability to absorb kinetic energy and store it as pure strength. Essentially, the more he was hit, the stronger he became. When he died, all the secrets of his discipline died with him. A few years ago a young sorcerer decided to train to be the first Kineticist in four hundred years. Do you know what happened?"
