Darby and Joan (also known as She's My Darling) is a 1937 British drama film directed by Syd Courtenay and starring Peggy Simpson, Ian Fleming, Tod Slaughter and Mickey Brantford.

Her elder sister Joan falls in love with Yorke Ferris, a work-shy rogue, but instead she marries his uncle, Sir Ralph.

Yorke is found shot and Sir Ralph is suspected, but Darby, with her acute sense of hearing, finds clues which exonerate him.

Peggy Simpson, lan Fleming, Mickey Brantford, and Pamela Bevan are the principal players, but their acting is as dated as the plot.
