These classic tales of mystery and suspense dating back to the earliest stories in the genre is, as far as I'm concerned, a real bargain for the true detective story buff. I think it also shows how the themes that make this type of literature what it is are themes that reward writers and readers across the ages. That's because the crime story deals with basic human interactions that never change. Police work that goes into solving crimes and bringing criminals to justice hasn't essentially changed either. Despite technical advances it was then, as now, a matter of dogged persistence and legwork. This collection should be in every true crime fiction lover's digital library.
