Black Wings Has My Angel by Elliott Chaze

 

Sort of a high-class, grad school version of Jim Thompson.  The shell-shocked veteran turned criminal teams up with the femme fatale to hatched an armored car robbery, using an abandoned mine shaft as the perfect getaway/hideaway where they can also bury the evidence.

Prose style strong, at times a litttle too self-conscious and minute for my taste. But I'd recommend the book to fans of noir crime fiction.
