Cats prowl at night

de Erle Stanley Gardner

**Cool & Lam Mystery #8** (1943) Donald Lam is off "whooping it up in Europe" when Everett G. Belder approaches Bertha Cool for help getting out of a financial jam. Simple. Straightforward. But not for long. An anonymous letter-writer aims to stir up trouble between Belder and his perennially suspicious wife, Mabel, who controls all the couple's assets. His mother-in-law has descended, Mabel has gone missing, and the maid--well. Poor Bertha has her hands full, trying to hold everything together long enough to collect her fee.
