An old lady who writes popular mystery novels strongly suspects that her niece's husband murdered her, so she exacts revenge by asphyxiating him in her house safe while devising a solid alibi. It's up to Columbo to unravel the subterfuge.
An aging but successful and wealthy crime fiction writer blames the death of her niece on the girl's husband. One night she invites him up to the house to sign their wills before getting him to leave and return within a few minutes so she can spring a trap (locking him in her soundproof safe). Detective Columbo arrives and suspects the writer of murder but clues are few and far between.—Scott Dawson <sdawson@easynet.co.uk>
