Hard Boiled or Private Detective

Not sure what to call this genre. Is Hard Boiled still in use?

Peter Cheyney; Dangerous Curves, White Circle are not exactly in the first division of cover design. I have too many Cheyney in stock to list, so if you are looking for something please contact me. I do try to check my email from time to time.
