I don't think I have listed this author on this site, yet, although she is not new to me. Jane Haddam-her protagonist is Gregor Demarkian who gets labeled "the Armenian-American Hercule Poirot" which he hates. He's a former FBI Behavioural Science Agent. Not officially working for anybody, but because of who he is everbody knows him and asks him for help, which means he gets involved in all sorts of fascinating situations. A wonderful character. The cover calls it "a Gregor Demarkian Holiday Mystery." I thought I had read a couple that were not set during a holiday but it may have been that the characters are so well drawn and the mysteries so well crafted that the holiday is just a setting and not the most important part. The one I just finished was Precious Blood, taking place during Easter in the overwhelmingly Catholic city of Colchester, NY
