Oh man I love Christmas mysteries. You need a little sour with your sweet in that season where things tend to overwhelm.
I read one every year, and the Poirot is really a good one, but I don't know about the website, haven't looked at it.
I want the big English manor, the snowstorm, the mystery afoot to go with the holiday jollity, for some reason I just love it. I think it's the same thing as A Christmas Carol, there we have ghosts with warnings and death intruding into the happy season.
They're not all cloyingly saccharine and painfully full of puns. Think of Charlotte MacLeod's (sp) Rest Ye Merry, charming wonderful thing.
Think of Simon Brett's The Christmas Crimes at Puzzel Manor, I love that thing dearly, I know a lot of people don't because he doesn't solve the last puzzle but it becomes a challenge: author versus reader. Just love that thing.
Barnes and Noble has brought out The Big Book of Christmas Mysteries and what a tome it is, in paperback, 654 large inviting pages, and what authors, Mary Higgins Clark, Agatha Christie, Ellery Queen, Colin Dexter, Peter Lovesey, the usual regulars Ed McBain, Ellis Peters, Ellery Queen, John D. MacDonald, Rex Stout, Robert Barnard, Mary Roberts Rhinehart, Damon Runyon, Thomas HARDY!!, O Henry and not the one you're thinking of, Robert Louis Stevenson, Isaac Asimov, Ngaio Marsh, Cyril Hare, and MANY many more new authors I have never heard of but whom those of you who love mysteries, regardless of which kind of mystery, would know.
I'm going to start with A Wreath for Marley, by Max Allan Collins, whom I never heard of. I think this book has something for everybody's taste, and who knows, one might discover a "new" or old author one likes. It's a lovely book and there's a little intro and bio for each author. Lovingly done.
ho ho ho!
