[These notes were made in 1990:]. Sulu, Scotty and Chekov are "disappeared" to various spots in their own cultural past: Sulu to Japan as a junior samurai, Chekov to WWII Russia, and Scotty to Jacobite Scotland. There each pursues dilemmas of loyalty and courage. Meanwhile, in the ST "present," Kirk pursues and eventually discovers the cause of their disappearance - a whimsical and intractable alien god-type - who lets them all go, also on a whim. I felt this one could have been focused a bit better - the dilemmas in the past were not sufficiently parallel, and did not have sufficiently pointed relevance to the main plot. Writing wasn't bad, though.
