English private investigator Matt Rider wants to find out if his grandfather killed Sophie Bernay in WW2, and uncovers an appalling international secret. Domestic Chemicals, a New York company owned by the Heinman dynasty, made poison gas for Nazi Germany. And now the past is back to haunt them -- like the bloated corpse Frank B. Heinman saw rising to the surface in the East River as a boy. Matt Rider in England and Frank Heinman in New York are on a collision course. The ex-president of Domestic Chemicals will make sure no one stays alive if he sees them as a danger to the company. Matt Rider just wants the truth. Hands of the Traitor is the first Matt Rider detective thriller.
