From: Private Eyes ed. Mickey Spillane and Max Allan Collins. Signet, 1998.
A retired San Francisco P.I. visits his old friend Karl, wanted by police for killing a black man in a case of road rage. After hearing Karl's side of things, that the man was beating on Karl's car, that Karl feared for his life, the P.I. doesn't believe a jury would convict him. However, Karl, dying from cancer, doesn't think he could stand a trial. He doesn't like the idea of dying in jail, either, so he's asked the P.I. to bring him an untraceable pistol.
In a short space, Knight poignantly parallels the two friends' lives. Steeped in despair, the story ends with the the P.I. walking away, listening for a gunshot.
