Cool & Lam Mystery #25 (1964)

Bertha Cool's latest scheme for attracting a more "respectable" class of clients begins with Homer Breckenridge and his All Purpose Insurance Company. Occasional all-expense-paid trips to an Arizona dude ranch, plus a handsome investigative fee, with nothing more for Cool & Lam's brainiest operative to do but try and nudge fraudulent injury claimants into a revealing slip-up. At least, that's all it is until Donald Lam decides Hermann Bruno is more than just a run of the mill malingerer.
