Poor Tom Is Cold is a 2004 made-for-TV film starring Peter Outerbridge, Colm Meaney, Keeley Hawes, and Flora Montgomery.
Constable Oliver Wicken (Philip Graeme) is found dead in the basement of an abandoned house, shot through the head.
While the rest of the police department believes he committed suicide, William Murdoch (Peter Outerbridge) thinks otherwise and sets out to prove that his friend and protégé was murdered.
While investigating Wicken's death, Murdoch comes across some interesting facts the late constable had kept hidden.
He discovers that Wicken was secretly engaged and had been working closely with a mysterious blonde woman before his death.
