This novel is really much more of a love story than a mystery, as Dorothy L Sayers herself acknowledged. But for readers who followed the story of Peter Wimsey and Harriet Vane through the three previous novels which featured both characters, it is a most satisfying love story and a welcome culmination to the years of Peter's patient courtship and Harriet's determined resistance. Tbere's enough of a mystery to make it worthy of being called a mystery novel, but no more than that. Apart from the love story and the mystery, Busman's Honeymoon is an interesting reflection of the era in which it was written, with its depiction of English attitudes to class and race (not critical, but descriptive and not the less interesting for that). There's a lot of French in it, which is ok for me because I am reasonably fluent in that language, but it must be a trial for readers who are not. I know how they feel, because there's a bit of Latin in there as well, the meaning of which I can only guess at. (I have an old edition of Busman's Honeymoon - probably printed in the 1970s - with no translations or notes: possibly more recent editions translate the bits which aren't in English?) Anyway, even if it could be considered pretentious by today's standards, I love the French and the Latin...and the poetry with which each chapter starts and which characters quote with abandon. They don't write mysteries like this anymore, more's the pity!
