Good mystery, easy to read, but not quite as exciting as I thought it would be. Though it has aged, the mystery is still as unsolvable as I'm sure it ever was. It did not convince me to read more Agatha Christie, though it was good. The killer was in my top three guesses, but I was never firm on any of them as there is little to no evidence in the book to figure out. Maybe upon a second glance, there is some evidence. So I shall take a look.
