From the train window Duncan Kincaid could see the piles of debris in the back gardens and on the occasional common. Lumber, dead branches and twigs, crushed cardboard boxes and the odd bit of broken furniture-anything portable served as fair game for Guy Fawkes bonfires. He rubbed ineffectually at the grimy windowpane with his jacket cuff, hoping for a better view of one particularly splendid monument to British abandon, then sat back in his seat with a sigh. The fine drizzle in the air, combined with British Rail’s standard of cleanliness, reduced visibility to a few hundred yards.

The train slowed as it approached High Wycombe. Kincaid stood and stretched, then collected his overcoat and bag from the rack. He’d gone straight to St. Marleybone from the Yard, grabbing the emergency kit he kept in his office-clean shirt, toiletries, razor, only the necessities needed for an unexpected summons. And most were more welcome than this, a political request from the AC to aid an old school chum in a delicate situation. Kincaid grimaced. Give him an unidentified body in a field any day.

He swayed as the train lurched to a halt. Bending down to peer through the window, he scanned the station carpark for a glimpse of his escort. The unmarked panda car, its shape unmistakable even in the increasing rain, was pulled up next to the platform, its parking lights on, a gray plume of exhaust escaping from its tailpipe.
