Jane and the Canterbury Tale, by Stephanie Barron
I've read some of these Jane Austen mysteries before, and they're kind of fun. This one has Miss Austen visiting her brother Edward. They attend the wedding reception of a local couple, the bride being a very young widow. But the next morning, her first husband shows up newly murdered and Jane has a complicated mystery on her hands.
This was an OK book, but to be honest I probably wouldn't have bothered to read the whole thing if I hadn't happened to have a terrible sneezy allergy attack for half of yesterday (poor me, I couldn't taste the pie properly!). I couldn't breathe and my head was completely stuffed up, so a brain-candy mystery was about all that I could handle.
The Regency slang and everyday detail is fun (very much like Georgette Heyer), and Barron makes strenuous efforts to fit the murder into the spaces between the lines of Jane Austen's documented life. So it won't drive you to drink or anything, it just wasn't that wonderful a mystery.
I did learn about mameluke sleeves, though, and what a hideous fashion they were.
