Mannix finds evidence that his death may not have been accidental, beginning with his discovery of rifle shell casings at the quarry.

When a prizefighter is gunned down during a match, the initial speculation is that he was punished for refusing to take a dive. But Joe Mannix, who happened to attend the match, speculates that the bullet may have been meant for someone in the audience -- and a review of the fight film suggests that the real target was Mannix himself. This is reinforced when there is another attempt on Mannix' life -- but the evidence begins to point to someone whom Mannix believes couldn't possibly have tried to commit the murder.
14 January 1973
Joe Mannix is visited by Portia and Penelope Penhaven, two elderly, eccentric sisters who insist that Mannix investigate a hit-and-run earlier that day, which damaged one of the headlights on their ancient automobile. Amused by their request, and overborne by Portia's forceful personality, Mannix agrees to look into the matter, but discovers that the vehicle that hit them was taken from a rental lot, apparently without the knowledge of the lot's owner. Digging deeper, however, Mannix soon discovers that the hit-and-run might be related to a murder committed nor far away on that same day.
