Wheelchair-bound June Anderson is strangled in the villa she is renting with husband Doug and sister Janice. Though Janice is her beneficiary and has no alibi Poole suspects Doug, a former colleague whom he knows to be corrupt and an alcoholic. Cleaning woman Estelle admits to stealing June's jewels but the net widens when Janice sees one of the two men who own the rental company from which they hired the villa running from the murder scene. An arrest is soon made but Poole suspects that June's murder may be linked to one in England some while earlier and solves the case by proving the connection.
