Another great entry in the Nate Heller series from Collins. This is the second Heller in the series after "True Detective" which I thought was also a super historical crime novel. In "True Crime", Heller gets involved with a setup to assassinate John Dillinger on the streets of Chicago in 1934. But was it really Dillinger who was killed? Heller doesn't think so. He then gets involved with Ma Barker and her boys, Pretty Boy Floyd, Baby Face Nelson and other "public enemies" in a plot to kidnap J. Edgar Hoover! As in "Detective", Collins really makes 1930's Chicago and the gangster era come alive. I give this one another high recommendation and look forward to more in the Heller series.
