Safe Secret by Harry Carmichael, Macmillan Company 1964, hardcover mystery, “A Cock Robin Mystery” Carmichael was the primary pseudonym of Leopold Ognall. He also wrote as Hartley Howard, mostly about PI Glenn Bowman. (thanks, Jeff)
“No matter how often men are warned not to mix big money and beautiful women, they don’t seem to remember the warnings very long. Richard Thornton remembered for about forty years, and then–as his employer, his wife, and his associates ruefully learned–Richard apparently forgot, to the tune of £35,000 of his employer’s cash.
Insurance investigator Piper, his reporter friend Quinn and Detective-Inspector Hoyle must find out where Thornton, and the money have gone.”
This is a fairly traditional British mystery, with a few plot twists and more than one deadly encounter. This is the first one I’ve read by this author, having chosen it after a review I read somewhere or other. A nice switch from the science fiction and fantasy on which I’ve been focused.
