This is one of Christie's spy thrillers which are never my favourite but I definitely preferred this one to They Came To Baghdad, which I read a few months ago. I read it in two days but still wouldn't describe it as a particularly gripping. It discusses a vague new world order conspiracy like a few of her other thrillers and I didn't find that very intriguing. There are some good plot twists and interesting characters and her writing is as good as usual but it's not one I'll remember.
