What do you do when everything you've held to be true, when your entire life, in fact, turns out to be a lie? When 22-year-old Steve Cline learns that he's illegitimate, and his real father is a race- horse trainer, he heads to the Maryland track. Steve's father recruits him to work undercover in an effort to discover who's been doping his most promising horses, and he quickly gets caught up in the unique lifestyle inherent to the backside. But it is not a life without peril because some men are willing to do anything to get the right horse under the wire first. REVIEWS:"Hidden away from the glittering stage of thoroughbred racing, with its flashing silks and gleaming horseflesh, is a place they call ''the backside.'' In her second stable mystery, DEAD MAN'S TOUCH, Kit Ehrman refers to this behind-the-scenes area -- where trainers, grooms, barn managers and stable hands minister around the clock to the needs of their high-strung charges -- as ''a world unto itself.'' Ehrman, who has worked at show barns and breeding farms, strikes a solid claim to this gritty territory with another heels-up thriller that takes up where Dick Francis left off. In the barn. Steve Cline, the young stable hand who made such a strong and sympathetic hero in ''At Risk,'' searches out the father he never knew, a thoroughbred trainer at a Maryland racetrack, and signs on as a ''hot-walker,'' a lowly exercise worker, when he discovers that someone has been fixing races by tampering with his father's horses. In true Francis tradition, Steve takes plenty of physical punishment as a sleuth. But his undercover role also gives him the inside track on life as it's lived on the backside, a grueling, even squalid existence that pays off in the chance to get close to the magnificent animals that have more character and heart than the two-footed fools who view them as a commodity." --Marilyn Stasio, NY Times ---This text refers to the hardcover edition.
