Devices and Desires - Episode Guide

Dalgliesh is on holiday in Norfolk but gets caught up in a series of murders.

"The Whistler" has killed again.

Dalgliesh finds another body which indicates that the murderer works at the nuclear power station.

There is a possibility that there are two murderers, one copying "The Whistler".

Dalgliesh's suspicions of Caroline lead him to a boat she has acquired while Theresa, rushed to hospital with appendicitis, tries to tell her father something she remembers about the murders.

"The Whistler" has killed himself, leaving a confession in which he denies murdering Hilary Roberts.
