Harrison Foster, a crisis manager for a London firm, is summoned to Newmarket after a fire in the Chadwick Stables kills six very valuable horses, including the short-priced favorite for the Derby. There is far more to the "simple" fire than initially meets the eye...for a start, human remains are found among the equestrian ones in the burnt-out shell. All the stable staff are accounted for, so who is the mystery victim? Harry knows very little about horses, indeed he positively dislikes them, but he is thrust unwillingly into the world of thoroughbred racing, where the standard of care of the equine stars is far higher than that of the humans who attend to them. The Chadwick family is a dysfunctional racing dynasty. Resentment between the generations is rife and sibling rivalry bubbles away like volcanic magma beneath a thin crust of respectability. Harry represents the Middle Eastern owner of the Derby favourite and, as he delves deeper into the unanswered questions surrounding the horse's demise, he ignites a fuse that blows the volcano sky-high. Can Harry solve the riddle before he is bumped off by the fallout?
