Fast and Loose was the second of MGM's brief "B" series based on Harry Kurnitz' husband-wife team of bookdealing sleuths, Joel and Garda Sloane. In Fast Company, the first of the series, Melvyn Douglas and Florence Rice played the Sloanes; in this second entry, the characters are portrayed by Robert Montgomery and Rosalind Russell. The murder victim this time is a celebrated rare book collector, and the motive is a missing first edition of Paradise Lost. The supporting cast included several likely suspects, including old reliable Ralph "Anything I Can Do to Help?" Morgan. Fast and Loose might have been faster and looser had it been shorter than 80 minutes.
