J. JEFFERSON FARJEON (1883-1955) was the author of more than sixty crime and thriller novels. His work was highly acclaimed in his day; Dorothy L. Sayers wrote that 'Jefferson Farjeon is quite unsurpassed for creepy skill in mysterious adventures'. Farjeon is now best known as the author of Number Seventeen, a play that was adapted for the big screen by Alfred Hitchcock. His Christmas crime novel, Mystery in White, was republished by the British Library in 2014, with Thirteen Guests and The Z Murders following in 2015.
