Death in the East, Mukherjee - B+

     In early 1922, Sam leaves Calcutta and travels up country to Assam, where he enters a Hindi ashram for the purpose of kicking his opium habit. He struggles through the first painful week, when he is distracted by, and asked to look into, the death of a fellow patient. This is also the first time in the series where there are extensive flashbacks to Sam's early days as a London policeman. As he is recovering in Assam, he attends an event and sees a man he knows to be a killer, whom all of London assumed had been dead for decades. Gaines/Carter recognizes Sam, but he he is dead before the night is over. Sgt. Surendranath conducts the investigation with Sam overseeing him. The official investigation of Gaines/Carter's demise concludes 'death by natural causes', but Surendranath tells Sam that he owes him a favor for looking away from the truth. Superb addition to the series.
