This is a delightful little chivalric romance, featuring a thoroughly likable main character, a plot full of juicy court intrigue, and the sorts of neat historical flourishes and turns of phrase you get when a story is written by a true scholar of the period. The story itself is well-constructed, with a satisfying amount of both swashbuckling action and political maneuvering; while its female characters are perhaps not greatly developed (it only passes the Bechdel test in form rather than spirit), they do exercise agency and have bearing on the plot, enough that I was genuinely surprised to learn that it was first published in 1950. If you like this sort of thing, it's an excellent read for a recuperation day or a long plane ride.
