Alexander Michael Stewart (born 25 July 1958) is a British writer. His best known work is fiction written under the pseudonym Sandy Mitchell—Warhammer and Warhammer 40,000 novels, including the Ciaphas Cain series.
A full-time writer since the mid-1980s, the majority of his work (as Sandy Mitchell) has been tie-in fiction for Games Workshop's Warhammer fantasy and Warhammer 40,000 science fiction lines, as well as a novelisation of episodes from the high tech thriller series Bugs, for which he also worked as a scriptwriter under his real name.
He has also contributed some Warhammer roleplaying game material (including Scourge the Heretic, the first tie-in book to the Dark Heresy roleplaying game) as well as a number of short stories and magazine articles.
He lives in the North Essex village of Earls Colne, with his wife and daughter.
As a member of the Midnight Rose Collective he edited the Temps and EuroTemps collections of short stories with Neil Gaiman.
In the Warhammer Universe, as ISFDB catalogues it, Sandy Mitchell is the sole author of Ciaphas Cain and Dark Heresy series (both listed completely here).
