Mannix has taken up a new hobby, amateur auto racing. While participating in a race, another racer is killed when his car seems to lose control and goes over an embankment. The widow of the dead racer contacts Mannix, wanting him to investigate, believing the death was a homicide. As Mannix proceeds, it's clear federal authorities have much more interest in what seems like a routine case. Written by
