Several years ago, I read a really bad mystery. The title was a clear attempt to cash in on a then-bestseller, the plot was ridiculous, the main character had too many "colorful" attributes (grad student AND bike messenger AND nude model for art classes AND lost her virginity to her professor-mother's colleague in a book-lined study - and all this by page 10), and the writing style was inappropriately flowery. It was awful, but it was fun to read.
The Rough Collier is a better-written book, but less memorable and less fun. Peat diggers find a preserved body, assume it's a recently disappeared local man, and a courtier visiting his mother deduces that it's not. So what happened to the missing man? It turns out he was murdered, but I never got interested enough in the characters to care how or by whom. The Rough Collier isn't a bad book, but it's mediocre and dull. I'm not going to look for any other books in the series, and I'm donating it to the Book Corner.
