I love magpies. They are so neat. Just had to say that.
This is a very, very clever book. What is more important it isn't impressed by its own cleverness. It's the reason I'm not that big of an Ian McEwan fan. He is never unaware of his own talent and ability and never lets you forget that.
Horowitz's clever book doesn't do that. It is so clever but not insulting. If you like British murder mysteries, this is a wonderful book.
