"And probably something to do with whoever killed this latest victim."

"There's another one?"

"In Ballinteer. Wheels up in fifteen."

He left the room and Valkyrie sighed, swung her legs out of bed. She took a quick shower, dressed, and Skulduggery had a bowl of cereal waiting for her when she emerged. When she had first visited his house, all those years ago, every room had been a living room. Now she had her own bedroom, there was a bathroom with a huge shower and a kitchen with a fully-stocked fridge. Sometimes she wondered how much money she'd cost him with her insistence on refurbishment, then realised she didn't much care. Money wasn't a big deal to someone like Skulduggery.

By the time they were both in the Bentley, her wits had woken up, too.

They arrived at the house in Ballinteer. As usual, there were Cleavers disguised as Guards making sure no one got too close. Philomena Random was talking to a news crew that had arrived. By the time Valkyrie got out of the Bentley, the news crew were packing up and heading away without filming a single frame.

Valkyrie let Skulduggery go inside. She didn't need to see any more blood. She waited at the door until he came back out.

"Same killer?" she asked.

"The method is different but the result's the same," he said. "This one was done by hand. The victim was thrown about the place like a rag doll. Plenty of footprints. Sloppy. Angry. Sadistic."

"Does that mean we have two killers?"

"If this murder is connected to the others, then I think we have at least two people working here, maybe more. This has all the hallmarks of a gang urging each other on. Each murder is more savage than the one before. Each time it gets more personal."

"Any idea why there's a car spread out like a jigsaw in the driveway?"

"None whatsoever."

"We have to find the link between the victims," Valkyrie said. "What was his name?"

"Thomas Purcell. Tommy. Twenty years old. Apprentice electrician. Mother absent, father works the nightshift, isn't home from work yet. Younger brother Doran, seventeen."

"Maybe he could help us," Valkyrie said. "If Tommy had any enemies, anyone who'd want to hurt him, his brother ought to know, right?"

"Maybe. That is if his brother is in any fit state to talk."

"Is he here?"

"Geoffrey's talking to him in the garage. See if he can be of any help. I'll take a look around outside."

Valkyrie nodded, walked to the garage and looked in. Geoffrey Scrutinous was sitting on a crate talking to a boy dressed in baggy jeans and a hoody. Geoffrey's hair was its usual wild and frizzy self, but he looked exhausted. These last few weeks had seen him rushing all around the country, convincing people they hadn't seen what they thought they'd seen.

"You can feel yourself calming down," Geoffrey said. "You're calm and you're clear. Oh, hello, Valkyrie. Valkyrie Cain, this is Doran Purcell. Doran lost his brother today."

"I'm very sorry," Valkyrie said.

Doran looked up at her. Geoffrey's routine had worked wonders. Doran looked remarkably calm.

"It's OK," he said. "Thank you."

"Do you mind if I ask you a few questions?"

Doran smiled. "You're my age. What are you doing, acting the detective?"

"I just want to talk to you, see if you can help us find out who did this terrible thing."

"Right," said Doran. "Terrible. Yeah. Sure, ask away."

"Thank you. Do you know who might have wanted to hurt your brother?"

Doran nodded. "Oh, yeah. Yeah, I got a good idea. Everyone who ever met him."

Valkyrie blinked. "I'm sorry?"

"My brother was a tool. He was a bully. He'd bully whoever he could get away with bullying. He had loads of enemies. Everyone wanted to hurt him. I'm telling you, there'll be a load of happy people today once this gets out."

"Are you happy, Doran?"

"Me? No. He may have been a bully but he was still my brother."

"Did he ever bully you?"

"Yeah."

"That must have been tough."

A shrug.

"Do you know who did this?"

"No. I got home late last night, came in the back door, went straight up to bed."

"Do you have any suspects?"

"Like I said, he had lots of enemies. Could have been anyone." A sliver of a smile played across his mouth, so quick Valkyrie wasn't sure she'd actually seen it. "You know who it could have been?" he asked, leaning forward. "Mark Boyle. He was Tommy's best friend, ever since they were little. Boyle was as bad as Tommy. They might have had an argument about something, and it got out of hand."

"It got out of hand?" Valkyrie said doubtfully. "Doran, have you actually seen your brother's body?"

"What there is left of it, yeah."

"And how do you think Mark Boyle would have done that?"

"I dunno. Knife? Maybe a chainsaw."

"That's a possibility," Valkyrie said. "Listen, will you be OK here for a moment? I'll have to start a search for Mark Boyle. If he's running, we'll have to act fast."

"Go get him," Doran said.

Valkyrie walked out, approached Skulduggery.

"I think we have our killer," she said quietly.

Skulduggery's false eyes flickered over her shoulder, looking back at Doran.

"He might be in shock," Valkyrie said, "so I might be reading this completely wrong, but he's practically dancing with joy now that his brother's dead. He also smells of soap."

"He'd need to have a shower to wash off all that blood," Skulduggery murmured. "Then it's another one of Argeddion's infections, you think?"

"Only this time the mortal with the magic is a psychopath."

"It was bound to happen. We can't take him down here. Someone that powerful, it'd be too unpredictable in a public place. We need to get him isolated."

"What'll we do?"

"Let him go, and follow him. Hopefully, he'll lead us to his accomplices. We'll assemble a team, take them all down at once, and no one needs to get hurt."

"What a lovely plan."

"Thank you."

"How likely is it to actually work?"

"With our luck? Not very."

Three hours later, her arms were folded and her brow was furrowed. "I hate this car."

Skulduggery dropped into a lower gear. "What's wrong with it?"

"It's orange."

"But a nice shade."

"It's horrible. It's an Orange-mobile. We're driving around in an Orange-mobile trying to be inconspicuous."

"We are being inconspicuous," Skulduggery said. "The Bentley, while the height of good taste in and of itself, is not suited to tailing somebody. This car, with its thoroughly unexceptional bodywork and engine capacity, blends in with the other cars on the road."

"Blends in?" Valkyrie repeated, looking around them. "Do you see any other orange cars out there? Do you? I don't. This doesn't blend in, it sticks out."

"And yet instantly fades from memory."

"I doubt it'll fade from my memory," she grumbled.

"Has Doran Purcell noticed us yet? No, he hasn't. Do you know why? Because the people he passes are not pointing at a beautiful black Bentley as it follows him slowly up the street. You should learn to appreciate the unexceptional, Valkyrie."

"But why does the unexceptional have to be such an awful colour?"

He shrugged. "It amuses me."

Doran Purcell walked into a cafe, and the Orange-mobile pulled in to the side of the road.

"I could do with some coffee," Valkyrie murmured.

"He might be meeting someone in there."

"I'll check," she said, reaching for the door handle.

"He knows you," Skulduggery said. A fresh face covered his head. "He doesn't know me. Stay here."

"Get me a coffee."

"No."

"Get me one."

He got out, crossed the road and entered the cafe. Valkyrie yawned, turned on the radio. An Imelda May song was playing 'Big Bad Handsome Man'. Valkyrie started singing along. She'd just got to the bit about his rugged good looks when Skulduggery came crashing out through the cafe window.

Valkyrie cursed, slid over to the driver's seat, started up the car and swerved out on to the road. Skulduggery staggered to his feet, ignoring the shocked looks from the people around him. Doran Purcell and two others a boy and a girl stepped out through the broken window behind him, grinning.

Valkyrie snapped her palm against the air, shattering the glass on the passenger side door. She sped past him and Skulduggery lunged at the car, using the air to take him to the window. He slid in and a stream of sizzling energy took out the wing mirror. Valkyrie cursed again, glanced in the rear-view and saw the three teenagers step into the middle of the road. The girl raised her arm and there was a flash of light and the car flipped and the world tilted and spun, then the car hit the road and flipped forward again. Everything blurred and roared.

When the world quietened down, the car was on its side and Valkyrie was in the back seat with blood in her mouth. She'd bitten her tongue.

Skulduggery's false face came into view. "Are you OK?" he asked, his voice distant.

She murmured, and nodded. Her clothes had absorbed the multiple impacts.

"We need to get out," Skulduggery said. "Move, Valkyrie. Now."

She turned over, noticing the pieces of glass embedded in her blood-drenched hand. Just cuts. Painful but not serious. She crawled out through the open door, on to the road. Her head ached. It buzzed. Doran Purcell and his friends were approaching, walking up the middle of the road, laughing to each other. Skulduggery appeared beside her, gun in hand. He fired, and the boys went to run but the girl stopped them. She gazed at the air, which had turned a hazy shade of blue a protective bubble to keep the bullets out. The girl giggled.

Skulduggery grabbed Valkyrie, dragged her behind the wreck of the car. She heard him fire again. She made herself sit up. Gunfire and energy blasts in the middle of the day in the middle of the street. She saw the faces of the people as they hid and peeked. She took a deep breath.

"Valkyrie," Skulduggery said. "I need you with me."

"I'm here," she said. She risked a glance around the bonnet, then ducked back to avoid an energy stream.

Skulduggery shook his head. "We need to get away. People are going to get hurt. If we're gone, they'll stop attacking."

"Can you fly us?"

"We'd be an easy target in the air. We have to break their line of sight first. Can you run?"

"I'm fine, I'm good."

"Well, OK then."

There was a boarded-up bookshop next to them. Skulduggery put his gun away and snapped his palms against empty space. The air rippled and the boards exploded inwards. He clicked his fingers, summoning flame.

"Ready?" he asked.

She nodded.
