The murder of a Vietnamese woman reawakens wartime trauma for cop John Thinnes and psychiatrist Jack Caleb in an "absolutely gripping" police procedural (Chicago Tribune).   After a woman is shot in the Little Saigon neighborhood of Chicago, Detective John Thinnes realizes he knew the victim when he was stationed in Vietnam. In fact, he was the best man when his friend Bobby Lee married Hue An. When an anonymous tip comes in that Thinnes might be the real father of her son, Tien Lee, who is the prime suspect in her murder, he is pulled off the case and his partner Don Franchi takes over.   At Hue An Lee's wake, a schizophrenic man insists there is a connection between her death and an unsolved murder in wartime Saigon. Psychiatrist Jack Caleb is called in to help the schizophrenic mourner, but the therapy is kicking up his own PTSD from serving as a medic during the war. Working with Caleb, Thinnes remembers a deadly criminal from his days as an MP in Saigon--known as White Tiger--who he fears has resurfaced in Chicago. Now it's up to the two vets to stop him . . .
