Lucy Malleson was born in
Upper Norwood, Croydon. She attended
St Paul's Girls' School. When her stockbroker father lost his job in 1914, the family suffered financial hardship, and she took up shorthand typing to earn a living. She began writing poetry, and then, inspired by the play
The Cat and the Canary by
John Willard (1922), she tried her hand at detective novels, using the name J. Kilmeny Keith. The first was
The Man Who Was London, published in 1925. She published over sixty crime novels as Anthony Gilbert, most of which featured her best-known character, Arthur Crook. Crook is a vulgar London lawyer totally (and deliberately) unlike the sophisticated detectives, such as
Lord Peter Wimsey and
Philo Vance, who dominated the mystery field when Gilbert introduced him. Instead of dispassionately analysing a case, he usually enters it after seemingly damning evidence has built up against his client, then conducts a no-holds-barred investigation of doubtful ethics to clear him or her. As fellow mystery author
Michael Gilbert noted, "...he behaved in a way which befitted his name and would not have been approved by the
Law Society." The first Crook novel,
Murder by Experts, was published in 1936 and was immediately popular. The last Crook novel,
A Nice Little Killing, was published in 1974. ==Adaptations==
