Death on the Nile by Agatha Christie
Death on the Nile is a classic Poirot mystery. Poirot is on vacation in Egypt, taking a cruise on the Nile - and of course a murder occurs. Happily, Colonel Race is on board too and the two of them take up the investigation.
We've got a lot of people on board the cruise, including a young couple on their honeymoon who are being stalked by the husband's ex-girlfriend, a young society man and his mother, a romance author and her daughter, an elderly kleptomaniac and her travel companions, a couple questionable men, a maid, a doctor - so many that it can get a little confusing on audio. The narrator did a good job with all the voices, but it's still a lot. The characters are all interesting and have their own personalities and motives. And Poirot likes them all, or almost all of them. He gives several people passes on their less serious crimes. It's the "hush, hush" house....
