Randy Johnson mentions the Rat Patrol novels in his comment on the previous post. There were five of these published by Paperback Library in the Sixties, when the show was still on the air. The first one was by veteran pulp author and paperbacker Norman Daniels, the other four by David King. I don't know anything about King except that he wrote a Western or two under his own name and also wrote at least one Slocum novel as "Jake Logan". I read all the paperbacks when they were new (bought 'em right off the spinner rack -- boy, I miss spinner racks sometimes!) and liked all of them. I've thought about rereading them to see how they hold up, but I have no idea where my copies are and haven't worked up the enthusiasm to search for them. There was also a Whitman juvenile novel based on the series by I.G. (Ivy) Edmonds that I wasn't aware of until I looked up the books on ABE. Edmonds is another author that's mostly a mystery to me. I know she wrote some stuff for the Girl From U.N.C.L.E. digest magazine and a few paperbacks, but that's it.
