They Came to Baghdad

I have been reading all of Christie's mysteries chronologically and this one was a breath of fresh air. It really isn't a mystery as much as a spy novel. The characters are likable and despite a relatively thin plot it is an enjoyable read. The plot revolves around an undercover group who plans to take over the world...which can only be stopped through secret messages and disguised operatives. All the same, I really liked it. It would have been fascinating to be in or read about Bagdad at the time it was written, though from our modern perspective it's quite different.
