I've not read any of her other books. Somehow I doubt that many guys would: I hesitate to use the term romance novel because the writing is infinitely better, but they are all mysteries, in which the female main character winds up with a new love in her life. Oops, I take it back--just remembered she's written one book for children--A Walk in Wolf Wood, or something like that. I've not read that one. But she can make you see places, that's for sure. I'd bet she's been to Greece, and that she really loves the place: three of her mysteries take place there, and in each the character raves about the country, particularly the light.
Interesting, how times change. Her earlier works were post-WWII, and the characters smoke, and the female willingly subjects herself to the wishes of the male.
I enjoyed the Merlin series as well--definitely a different point of view.

Oh, yes; I was wondering earlier: I used the term 'main character'; is the word 'protagonist' appropriate only when you're talking about a play?
