Hetty is called on by a pair of worried parents whose deaf-mute son, Malcolm, has disappeared while out bird-watching. To make matters worse, a woman is found dead at the bottom of a cliff which Malcolm is known to frequent. Is foul play at hand? Malcolm, as it turns out, is on the run because he witnessed a murder. The murderer turns out to be one Sergeant Lennox, a rogue policeman now bent on finding Malcolm and keeping him quiet - for good. Hetty and Geoff's search proves more difficult than expected, especially after Lennox is assigned to work with Hetty on the case.
