Detective Sergeant George Cross can be difficult to work with, but he doesn't miss a clue. So when the body of an elderly homeless man is discovered, he insists on scrutinizing the smallest details, even after his police colleagues dismiss the murder as an act of random violence. As Cross delves into the dead man's past, he discovers a connection to a case that has been cold for fifteen years. The same tragedy that led to his homelessness may have also led to his death. Cross may be the only person who can solve both cases-and finally arrest the murderer who has roamed free.
