John Dickson Carr (writing as Carter Dickson) was born in 1906 in Uniontown, Pennsylvania, the son of a lawyer. While at school and college, he wrote ghost, detective and adventure stories. After studying law, he headed to Paris in 1928. Once there, he lost any desire to study law and soon turned to writing crime fiction full-time. His first novel, It Walks by Night, was published in 1930. Two years later, he moved to England with his English wife; thereafter he became a prolific author and became a master of the locked-room mystery. He also wrote a biography of Sir Arthur Conan Doyle, radio plays, dozens of short stories, and magazine reviews. He died in 1977 in South Carolina.
