Quincy is asked to do an autopsy on the body of a marine who died in an accident during his training. Harry Collier, a friend of Quincy's wants him to give a second opinion, to stop the press from calling the death a cover up. What Quincy finds though is what he thinks is evidence of a murder and he goes to the base to find out what did happen to cause the young soldiers death, and if necessary who caused it.

A courier they were following was killed when a bus at the airport and, as Quincy is going to a Las Vegas to judge a Miss Coroner Contest; they want him to take the couriers place. He has to deliver the diamonds to a known mobster, something he really, really does not want to do!
