Query: Couldn't finish it.

I was all set to enjoy a classic mystery. I couldn't do it. The setting was the usual sojourn in the country with innumerable suspects. The characters were stock. I couldn't keep them straight, and I had no interest in doing so. Maybe I would have enjoyed the book if I could have stuck it out to the end, but it wasn't worth it.
