Dear Murderer is a 1947 British film noir crime, drama, thriller, directed by Arthur Crabtree for Gainsborough Pictures, and starring Eric Portman and Greta Gynt.

On his return from a lengthy business trip to New York, suspicious after his wife failed to write to him or call, Lee finds several cards addressed to Vivien signed "Love Always" and determines to kill her latest lover, Richard Fenton.

He confronts Fenton, who admits to his affair with Vivien, and persuades him to end the relationship by writing her a farewell letter.

Lee changes his testimony to the police to say that Fenton had died of suicide but that he had later manipulated the crime scene to look like he was murdered by Martin.

Vivien returns dejectedly back to her apartment and, despite initially feigning distress at her husband's death, is arrested by Pembury for Lee's murder.

"[14] It also received positive notices on its release in the U.S.: "Another masterful picture from overseas, a carefully plotted dramatic thriller which revolves very neatly about the commission of the perfect crime.
