One Good Turn (subtitled A Jolly Murder Mystery) is a 2006 crime novel by Kate Atkinson set in Edinburgh during the Festival.

Justine Jordan of The Guardian enjoyed the novel, saying Liesl Schillinger of the New York Times said, "Kate Atkinson shows again, in her inimitable bleakly funny way, how much easier it is to explain a death than to solve a life.

"[3] In "no hurry to judge," Atkinson "acts like a hidden camera, dispassionately recording her characters’ deeds and misdeeds so they can indict themselves.

Indeed, she has woven the technological accessories of the last 10 years into the fabric of her story, threading them through it like an invisible current into which the lives of all her characters are plugged.

"[3] But Amanda Craig writing in The Independent says This novel was “shortlisted for the British Book Awards Crime Thriller of the Year.”[4] The novel was adapted for television with two other of Atkinson's Brodie series for the BBC in 2011 with the overall title Case Histories.
