Synopsis by Hal Erickson
Based on a story by Bela and Samuel Spewack, Solitaire Man stars Herbert Marshall as Oliver Lane, a "diamond expert" (read: master jewel thief). During a plane flight across the English channel, Lane becomes aware that practically every member of his gang plans to double-cross him -- not that the crooks trust one another any more than they trust their boss. Even detective Wallace (Lionel Atwill), assigned to keep tabs on Lane, turns out to be a double-crossing scoundrel. Under the circumstances, Lane becomes the film's hero by default. Practically the only person worth caring about in the story is heroine Helen (Elizabeth Allen) -- and one has one's doubts about her.
