Edogawa Rampo was the pseudonym of Taro Hirai (1894-1965), generally viewed as the greatest of all Japanese suspense and mystery authors. He was a prolific novelist and short story writer. Much influenced by writers such as Conan Doyle, Chesterton and Wells, his pseudonym is a Japanese transliteration of Edgar Allen Poe's name. Many of his works have been made into films. Perhaps his most famous stories outside Japan are 'The Caterpillar' and 'The Human Chair'.
Ian Hughes lived for many years in Japan, working first as an English teacher in the countryside before moving to Tokyo and becoming a professional translator. His fiction translations include Beast in the Shadows, another Edogawa Rampo classic.
