Tarot and Ceribraun play out the final moves in a dangerous and complex game of double-cross.

Tarot meets up with Chas and Mikki, a brother and sister, who live in a studio over an old London street market. Chas is a photographer, and Mikki a freelance journalist. Mikki is worried about a series of inexplicable accidents in the market, although Chas is inclined to laugh the whole thing off..

Tarot begins to put together the pieces that make up the mysterious happenings in the street-market. Why are Spoon and the other musicians always around, even when the market is closed? Is Mockers, the "prophet of dooom", in league with them? And what is the role of Mr Dove, watching over the market through binoculars from his tower-block office?
