This contains three stories in which interstellar medic Calhoun and his cute furry alien sidekick Murgatroyd visit far flung planets and foil evil plots or dispel foolish delusions involving major medical crises. They are straightforward space adventures with a touch of comedy and just enough space-tech stuff to reassure. The story is the thing. I suspect they’re the kind of stories that were killed by television, supplanted in the lives of young readers by the likes of Star Trek and Doctor Who. I mourn their passing.

On the basis of the cover and the blurb, I was expecting a museum piece, but actually the book is great fun. My sorrow at its being out of print since 1966 was mollified when I discovered that Leinster wrote a total of eight Super-Medic stories, and in 2001 all eight were collected into an omnibus, Med Ship, edited by Eric Flint. Lots of bits of Calhoun and Murgatroyd can be found online by straightforward googling.. ( )
