Detection Club

In addition to meeting for dinners and helping each other with technical aspects in their individual writings, the members of the club agreed to adhere to Knox's Commandments in their writing to give the reader a fair chance at guessing the guilty party. These fair-play "rules" were summarised by one of the members, Ronald Knox, in an introduction to an anthology of detective stories. They were never intended as more than guidelines, and not all the members took them seriously. The first American member (though then living in the UK) was John Dickson Carr, elected in 1936.

The club continues to exist, although the fair-play rules have been considerably relaxed.

A number of works were published under the club's sponsorship; most of these were written by multiple members of the club, each contributing one or more chapters in turn. In the case of The Floating Admiral, each author also provided a sealed "solution" to the mystery as he or she had written it, including the previous chapters. This was done to prevent a writer from adding impossible complications with no reasonable solution in mind. The various partial solutions were published as part of the final book.

The founding members of the club in 1930 were H. C. Bailey, E. C. Bentley, Anthony Berkeley, G. K. Chesterton, Agatha Christie, G. D. H. Cole, Margaret Cole, J.J. Connington Freeman Wills Crofts, Clemence Dane, Robert Eustace, R. Austin Freeman, Lord Gorell, Edgar Jepson, Ianthe Jerrold, Milward Kennedy, Ronald Knox, A. E. W. Mason, A. A. Milne, Arthur Morrison, Baroness Orczy, John Rhode, Jessie Rickard, Dorothy L. Sayers, Helen Simpson, Constance Lindsay Taylor, Henry Wade, Victor Whitechurch and Hugh Walpole.^[1]

Over the following two decades further members were elected to the club: Anthony Gilbert (1933), E. R. Punshon (1933), Gladys Mitchell (1933), Margery Allingham (1934), Norman Kendal (1935), R.C. Woodthorpe (1935), John Dickson Carr (1936), Cecil Day-Lewis (1937), Muna Lee (1937), Maurice Guinness (1937), E.C.R. Lorac (1937), Christopher Bush (1937), Cyril Hare (1946), Christianna Brand (1946), Richard Hull (1946), Alice Campbell (1946), Val Gielgud (1947), Edmund Crispin (1947), Dorothy Bowers (1948), Douglas G. Browne (1949), Michael Innes (1949), Michael Gilbert (1949)^[2] and Mary Fitt (1950).^[3]

Membership was initially limited to those considered to be writing pure detective novels, rather than mystery thrillers. This began to change when Eric Ambler, known for his thrillers and spy novels, was elected in 1952.^[4] Several notable detective writers including Philip MacDonald and Josephine Tey were never invited to join the club, while Georgette Heyer who wrote detective stories alongside her better-known regency novels turned down an invitation. Daily Express columnist Nancy Spain was considered for membership but was rejected.^[5] Future president Julian Symons was initially rejected before eventually being admitted in 1951. Ngaio Marsh, a major figure in detective writing, only joined later in life.^[6]

Subsequent members of the Club included Andrew Garve, H. R. F. Keating and John Bingham. Martin Edwards charted the early history of the Club in his 2015 book The Golden Age of Murder.

Do you promise that your detectives shall well and truly detect the crimes presented to them using those wits which it may please you to bestow upon them and not placing reliance on nor making use of Divine Revelation, Feminine Intuition , Mumbo Jumbo, Jiggery-Pokery, Coincidence or Act of God?^[7]
