Accomplice is a 1946 American thriller film directed by Walter Colmes and starring Richard Arlen, Veda Ann Borg, Tom Dugan, and Archie Twitchell.

Blonde bombshell Joyce Bonniwell hires her ex-fiancé and Los Angeles attorney, Simon Lash.

She admits to having an affair with Sam but that she has not seen him for several days although he may be taking refuge at the Castleman's Mink Ranch, a place he owns near Palmdale.

Simon starts to suspect that Joyce might be seeking out hard evidence of Sam's infidelity, possibly for divorce proceedings.

When they arrive together to the crime scene, the sheriff starts to suspect that Simon and Joyce have murdered Sam to get his money from the inheritance.

Simon contacts Eddie by phone, and receives information that both Evelyn and bank president Springer have disappeared without a trace.

Simon learns from Joyce that the bank president's fiancée is a brunette, and decides to find the woman.

Simon then continues to explain that Evelyn, who was really Springer's mistress, not Sam's, and Castleman both were murdered to prevent them from revealing the truth.
