Swampy's Florida

The legendary creator of the Toff mysteries, John Creasey, wrote a series of 6 novels under the pseudonym Robert Caine Frazer. The series appeared from 1959 to 1962 and is about British private investigator Mark Kilby who mostly worked for large businesses and reflected that echelon of client in dress and manner. His secret weapon is a hidden double ended gold tipped cane that held a small sword inside. Here’s one of the series from 1960 that involves Miami with a Miami-ish cover of the time.
