Kevin “Fishy” Broom has his nickname for a reason-a rare genetic condition that makes his sweat and other bodily excretions smell markedly like rotting fish. Consequently, he rarely ventures out of the London apartment where he deals online in Nazi memorabilia. But when Fishy stumbles upon a crime scene, he finds himself on the long-cold trail of a pair of small-time players in interwar British history. First, there’s Philip Erskine, a fascist gentleman entomologist who dreams of breeding an indomitable beetle as tribute to Reich Chancellor Hitler’s glory, all the while aspiring to arguably more sinister projects in human eugenics. And then there’s Seth “Sinner” Roach, a homosexual Jewish boxer, nine-toed, runtish, brutish-but perfect in his way-who becomes an object of obsession for Erskine, professionally and most decidedly otherwise. What became of the boxer? What became of the beetle? And what will become of anyone who dares to unearth the answers?
