Rogue's Yarn is a 1957 British second feature[1] crime drama film directed by Vernon Sewell and starring Nicole Maurey, Derek Bond and Elwyn Brook-Jones.

[3] John Marsden is conducting a passionate affair with Frenchwoman Michele Cartier, but their hopes that his wealthy invalid wife will soon die are thwarted by her recovery.

Pressured by his lover, Marsden begins planning a perfect crime to murder his wife at the family home while he is supposed to be sailing on his yacht between Newhaven and Le Havre in Normandy.

The Monthly Film Bulletin wrote: "A routine detective story of the "how-he-did-it" school, fairly interesting in plot but sometimes over-calculated in presentation.

The two principals are dull, but John Serret is entertaining as a French police official, while Elwyn Brook-Jones avoids the hackneyed in his characterisation of a Scotland Yard man – though his disrespect for superior authorities seems somehow unlikely.
