I haven't read any of these, so can not comment on them. However, these are all authors who were popular in their day and still are looked for from time to time. In the store, they are all grouped together in their own place.
J. D. Carr, M. Allingham, C. Dickson, P. Dickinson, C. Dexter, J. Creasey, A. Cross, M. Eberhart,and N. Freeling.
The store also has a bunch of Ross MacDonald, a few Raymond Chandler and a lot of John D. MacDonald. John D. MacDonald was the author of the popular Travis McGee series, of which I read every one (and have my own private collection at home) and plan to read again some day. If you have never read one, give it a try.
