British playwright Anthony Shaffer is the author of many works for the stage and screen, including the original versions of Sleuth, cult horror film The Wicker Man and Alfred Hitchcock's suspense thriller Frenzy. He also adapted several of the star-studded Agatha Christie stories for film and developed ideas and storylines for other known titles.

His work in theatre was also prolific, with his long-running stageplay Sleuth breaking box-office records in the West End and on Broadway. Murderer, Shaffer's dark, twisting, comedy thriller also took up residency in the West End and its unusual graphic and macabre opening scenes set a new standard in theatre, years before gore and blood became the norm for some productions.

Shaffer forged a unique writing style of his own, combining his love of the murder-mystery genre, practicle jokes and games playing, often twisting them into what Shaffer described as: "turning the truth upside down."

A menacing pattern of psychological teasing lurks thoughout his work and his storytelling is told through intricate and twisting plots, sharp, witty dialogue and doses of dark humour.

Milton Shulman, writing in the London Evening Standard, states:

"It is Shaffer's special gift that he can lead an audience up a dramatic cul-de-sac, and then surprise them by finding an ingenious exit no-one could suspect was there... he succeeds in gripping our attention with vice-like efficiency."
