Not an often shown film, nor a great one, this is worth your time if TCM ever shows it again. The plot is somewhat dated but nevertheless interesting -- code breaking and spy catching -- if you ignore some of the excesses that were probably added by Hollywood. Folding in comedy, drama, and action into what would probably have made an excellent military training film, we are left unsatisfied with the overall effect. Yet there is a hint of the "Thin Man" chemistry between William Powell and Rosalind Russell that brings a smile to your lips. Fair but I am not sorry that I watched it.
