Sam Wyndham series

India, 1921. Captain Sam Wyndham is battling a serious addiction to opium. When Sam is summoned to investigate a grisly murder, he is stunned at the sight of the body: he’s seen this before. Last night, in a drug addled haze, he stumbled across a corpse with the same ritualistic injuries. Unfortunately for Sam, revealing his presence in the opium den could cost him his career. He must try to solve the two murders, all the while keeping his personal demons secret, before somebody else turns up dead.
