This short story appeared in the February 1950 issue of Adventure Magazine. The author, George C. Appell, was a prolific pulp author found in many magazines and later paperbacks from 1944 to 1957. He mostly wrote westerns but also occasional work for the mystery pulps and general fiction titles like Short Stories and Adventure. This is the second Legion story by him that I’ve posted here.
Desert Trap takes place after WW2 and brings the Legion into the modern age with jeeps and ex-Nazi’s but keeps the desert forts. It’s pretty much a tale of murder and revenge played out in the inferno of the Sahara desert. I’m surprised it featured as the magazine’s cover illustration but I’m glad it did because the cover is awesome.
