Samson Roach is hired on a real dog of a case--to find the pedigreed poodle of very wealthy Mrs. Winnick which had disappeared with her granddaughter, Panda. The tracer leads from a pet parlor, Chez Chien, to an even noisier establishment, the Jaguar Club, and it entails blackmail, blue pictures, drugs, a couple of murders, and a supposed suicide of many years ago. . . . Mr. Squerent typed this one with his knuckles but it's snarlingly active.
