clerihew

Edmund Clerihew Bentley, a friend of Chesterton from schooldays, issued his first clerihew, which is a whimsical, four-line biographical poem that he invented, in 1905, on Sir Humphry Davy.

Bentley was also president of the Detection Club, a club for mystery writers, which included Agatha Christie, Dorothy Sayers, and Ronald Knox. Chesterton was its first president. Per Wikipedia, “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.” Knox just happened to be a Catholic priest, and Christie just happened to sign a 1969 letter requesting that the Latin Mass not be abolished.

This time period is called the Golden Age of Detective Fiction. Most of the writers were British, but included are Americans Ellery Queen, Erle Stanley Gardner (of Perry Mason fame), Dashiell Hammett, and Raymond Chandler.
