Compliments of a Fiend [EPUB ebook] 

A detective scours Chicago for his missing uncle in this classic mystery by “a real pro—a natural storyteller” (The New York Times Book Review).   Young Ed Hunter and his uncle Ambrose, an ex-carnie, have been making their mark as private detectives in post-WWII Chicago, and one day their agency gets a call from someone seeking help. Apparently, the problem involves carnivals, so Ambrose steps in to put his expertise to work—and then disappears.   To find his partner, Ed will have to pound the seedy streets of the city, get involved with a fortune teller, and delve into an old story about an “Ambrose collector, ” in this smart, quirky entry in the Edgar Award–winning series.
