Pulp is pulp, but this one moves along and has something new in the way of setting -- the ""off-the-course horse race betting"" racket. Joe Duggan, cheap Irish product of Kansas City slums, learns the lay of the races at the poolroom. Good natured and quick-witted, he moves to Chicago and works for the wire service, to all poolrooms, a profitable but straight game. But the gangsters get in, the Jockey Club gets out, and Joe is played for a sucker by gang and a woman -- and his service cleaned out. A Kentucky girl comes into the picture and helps him. Factual background rings true. A good yarn.
