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.

In the hours before his death, Lord Comstock's visitors included the government Chief Whip, an Archbishop, and the Assistant Commissioner for Scotland Yard.
