Many fans of JDC have expressed interest in reviving the John Dickson Carr Society. The original was based in Oxford (under Crispin) and seems to be defunct. The premise of meeting in a pub every third Friday or whatever (like the Inklings with their weekly Tuesdays) is remote, as wonderful as that would be, but I am willing to set up JDCS as a web site -- and have, already:

There is no membership list yet, but please have a look and give me advice -- appearance, content, et al.
