Valkyrie sighed. She didn't envy the detective in the interrogation room. Skulduggery was getting increasingly bright and cheerful which meant he was really, really close to punching someone.

She decided to leave before someone arrested her as well.

Valkyrie walked out of the building silently. She wandered a few streets from the museum and when she was confident no-one from the Sanctuary was following her, called a taxi.

If anyone had any answers to this, her uncle would and even if he didn't, he'd know how to find out.

She told the driver directions then stared out of the window into the darkness. It was too early to be working. Or too late. She wasn't really sure where one ended and the other began.

The cab had finally arrived at Gordon's house. No matter how long she owned it, it would always be Gordon's house, not hers.

She paid the driver, ran right up to the study and pulled out the ancient leather book. She grinned as the bookcase swung open, still unable to get over how amazing the secret room was.

The blue Echo Stone in the middle of the room glowed and her late uncle appeared, smiling at her.

"Hello there, is the world in danger again?"

Valkyrie smiled. "No, not this time"

"I assume you aren't just here to visit your beloved, dead uncle"

She shook her head. "Skulduggery's been arrested by the new idiots at the Sanctuary"

Echo-Gordon leaned in. "Why?"

"People have been getting murdered."

"So why have they arrested Skulduggery?"

"They've been murdered by a skeleton"

Gordon looked at her curiously. "How?"

"They've all been set on fire"

Echo-Gordon grinned.

"What are you so happy about?"

"I know who did it. Or, actually, what did it."

"What?" Valkyrie said quietly, stunned.

"I was meaning to write a book on them. I suppose I can't now I'm dead..." Gordon trailed off.

"what killed them, Gordon?"

He grinned again.

"A Ghost Rider"
