The dark side of town

McKee, now officially employed by the Thoroughbred Racing Protective Bureau (TPRB), is sent undercover to Saratoga Racetrack to investigate Mars Pizutti, a racehorse trainer whose horses' wins are suspiciously lucky--and lucrative. Fia's bosses believe Pizutti's success is based on illegal drugs and deceitful methods, and they want Fia to work inside his barn to ferret out the truth. But after witnessing the tragic and inexplicable suicide of a jockey, Fia discovers the rider's death is only the tip on an iceberg.
