"The Detection Club is a private association of writers of detective fiction in Great Britain, existing chiefly for the purpose of eating dinners together at suitable intervals and of talking illimitable shop ? Its membership is confined to those who have written genuine detective stories (not adventure tales or 'thrillers') and election is secured by a vote of the club on recommendation by two or more members, and involves the undertaking of an oath." Dorothy L. Sayers.
