Yes yes, the wound may have been self-inflicted, but not with the knife found in the man's lap. But it wasn't this neat. A banker wanted to let his family cash in on his life insurance before the cops stumbled onto his embezzling. So he staged his own murder. The guy survived and finally confessed.
Duty hangs up, considers the facts.
The dead man apparently had the motive, but he didn't have the means. If the knife the cops found in his lap didn't match up to the wound, then it was obviously a plant meant to misguide the police. He calls the coroner back. N ext morning back to the amusement park, which in the daylight looks smaller and, without the neon, less impressive. Once around and then Duty stops at the Ferris wheel.
