Lady in the Lake is a 1947 American film noir starring Robert Montgomery, Audrey Totter, Lloyd Nolan, Tom Tully, Leon Ames and Jayne Meadows. An adaptation of the 1943 Raymond Chandler murder mystery The Lady in the Lake, the picture was also Montgomery's directorial debut, and last in either capacity for Metro-Goldwyn-Mayer (MGM) after eighteen years with the studio. Montgomery's use of point-of-view cinematography and its failure was blamed for the end of his career at MGM.

Plot

Tired of the low pay of his profession, hard-boiled Los Angeles private detective Phillip Marlowe submits a murder story to Kingsby Publications. He is invited to the publisher's offices to discuss his work, but soon realizes it is merely a ploy. A few days before Christmas, publishing executive Adrienne Fromsett hires him to locate Chrystal Kingsby, the wife of her boss, Derace Kingsby. One month earlier, Kingsby’s wife had sent her husband a telegram saying she was heading to Mexico to divorce him and marry a man named Chris Lavery. But, according to Fromsett, Lavery says he has not seen Chrystal for two months, and the telegram appears to be fake. It becomes obvious to Marlowe that Fromsett wants her boss for herself.
