J. J. Connington

Born in 1880, Alfred Walter Stewart wrote detective fiction under the name J. J. Connington. He was a British chemist as well as a novelist, and his scientific background helped give his crime stories their careful logic and sense of method.

Alongside his academic work, he published a substantial body of popular fiction, especially mysteries that appeared during the classic interwar period of detective writing. He is particularly associated with puzzle-style crime novels and with the character Sir Clinton Driffield.

Stewart died in 1947, but his books have continued to interest readers who enjoy traditional detective stories with intricate plots and a distinctly analytical touch. He is also remembered in science-fiction reference works, reflecting the range of his writing beyond straightforward crime fiction.
