Synopsis: Professor Peter Shane is the expert on Chicago's criminal gangs, having written a large dissertation about them. Prohibition gang boss --- Salamo is found dead on the dance floor of the Cotillion Club, his girlfriend Hippolyte Bora posing nearby in a slinky dress.
The police call in Shane and fellow professor Francis Bonnamy (in a multiple role as author, narrator, and professor) to investigate, due to their exhaustive research and knowledge of gang activities. The Medical Examiner is called, and despite there being a stiletto found on the body, finds the wound was made by something much longer - a rapier.
Review: This immediately struck me as being structured like the S. S. Van Dine novels. Like those, the author has inserted himself/herself into the text as the narrator, so Francis Bonnamy is one of the characters - a professor at the University of Chicago.
We are treated to the world of 1920's prohibition gangsters, always well-dressed and with perfect manners (think of Guys and Dolls); although with obviously limited education. It is amusing how the two professors use "big" words which the gangsters don't understand, and have to resort to dumbing down their vocabulary.
