The idea of presenting Veronica Lake as the heroine of an exciting melodrama has its merits. But the material selected is distinctly unsuited to her. It is a very involved yarn by Graham Greene which deals with international intrigue and treason, having to do with the sale of a secret chemical formula to the Japanese. Albert Maltz and W.R. Burnett wrote the screenplay, which is a succession of gunplay scenes in which Lake becomes the unwilling accomplice of a young killer. He is Alan Ladd.
Other players in the film had difficult assignment trying to give some credence to an improbable story. Robert Preston plays a policeman, who is too easily outwitted to deserve Lake in the end. Laird Cregar is an interesting heavy, and Tully Marshall a reprobate of the worst kind.
