Gerry Maddren

Gerry Maddren appears to have had a modest but varied publishing career. Confirmed records show the science-fiction story The Alternate Plan in the September 1958 issue of Amazing Science Fiction Stories, and the work remains available through Project Gutenberg.

Later, Maddren moved into mystery fiction with The Case of the Johannisberg Riesling, published in 1988 by Cliffhanger Press. Listings for that edition describe it as the first Jerry Cool novel, set around San Francisco and the Carneros wine district.

Reliable biographical details beyond the published works are hard to verify from readily available sources, so it is safest to remember Maddren primarily through the fiction itself: a writer whose name turns up in mid-century magazine science fiction and, decades later, in an offbeat California mystery.
