Harry Thaws an Icy Murder

An unlikely group of burglars and their ringleader loot the vault at Commonwealth Bank & Trust. They pull it off without a hitch. Almost. A clue is found at the scene and a night guard is killed - bludgeoned to death. Police interrogate suspects but nobody cracks. Do they have the wrong suspects? Is the clue a red herring? A year later, no one's under arrest, the money hasn't surfaced, and the guard lies unavenged in his grave. "I want you to find his killer and the stolen money!" the bank president tells Harry. Can he do what the police couldn't? Maybe so, but not without help from his wife, Cardamine - even if he doesn't welcome it.
