I wished both women well, then turned and raced back for camp. I tried not to dwell on all that could happen to them on their way to the Mountain, and offered up a quick prayer to the gods of the vampires as I ran, asking them to watch over the ex-Chief Inspector and the teacher I loved.

I was on the edge of the camp when I spotted Mr Tiny and Harkat in an open field. In front of the pair stood a shimmering arched doorway, unconnected to anything else. The edges of the doorway glowed red. Mr Tiny also glowed, his suit, hair and skin pulsing a dark, vibrant, crimson shade. The space within the edges of the doorway was a dull grey colour.

Mr Tiny heard me coming, looked over his shoulder and smiled like a shark. "Ah Master Shan! I thought you might turn up."

"Darren!" Harkat snapped furiously. "I told you not to come! I won't take you with … me. You'll have to"

Mr Tiny laid a hand on the Little Person's back and shoved him through the doorway. There was a grey flash, then Harkat disappeared. I could see the field through the grey veil of the doorway but no sign of Harkat.

"Where's he gone?" I shouted.

"To search for the truth." Mr Tiny smiled, edged aside and gestured towards the glowing doorway. "Care to search with him?"

I stepped up to the doorway, gazing uneasily at the glowing red edges and the grey sheen between. "Where does this lead?" I asked.

"Another place," Mr Tiny answered obscurely, then laid a hand on my right shoulder and looked at me intently. "If you follow Harkat, you might never return. Think seriously about this. If you go with Harkat and die, you won't be here to face Steve Leonard when the time comes, and your absence might have terrible repercussions for vampires everywhere. Is your short, grey-skinned friend worth such an enormous risk?"
