These are interesting stories in their way. The puzzles are ingenious, and as you would expect that means the solutions are sometimes a bit contrived (this happens in a lot of mystery stories, to be fair). The writing style creaks somewhat, a hundred years after they were written, but that doesn't get in the way of enjoyment. I do find myself re-reading these tales, so yes, they are appealing.
Enjoyed this book very much but unfortunately this files in only the original volume one when you download the Palm (pdb) version. Would love to read the rest of the book.
Keith Laumer is not new to science fiction and was an old pro who had written some of the best and most humorous science fiction adventures stories ever written. His best works are from before 1970 but wrote some interesting works until his passing in 1990.
Greylorn is a fun romp but if you want to read his best, try the Retief stories as well as Time Trap, Dinosaur Beach and Earthblood,
good good good............
