A woman is murdered on a street near Peggy's home, and Joe Mannix is the first one to reach the murder scene. Joe questions a neighbor in a nearby house, and concludes the man may have seen more than he will admit. Hired by the deceased woman's husband to try to find her killer, Joe pursues the case and uncovers evidence leading to the uncomfortable conclusion that the woman's killer might be the son of one of Peggy's old friends -- and that he might also be responsible for the disappearance of the witness.
