Flesh, the Blood and the Fire, The by S. A. Swiniarski

"Between 1934 and 1944, Elliot Ness and his agents were in Cleveland investigating the Kingsbury Run case, in which bloodless bodies were found along the train tracks. Ness raided and burned out Cleveland's shantytowns in his efforts to find the killer. Unwilling to concede defeat, one cop continues to follow the bloody trail and discover that the law is not dealing with the mob or a serial killer--but with a community of vampires."
