I am not going to start listing mystery novels I have loved because I made a rec list for someone once of my 100 favorites--I think I lost it with a computer crash also! Off the top of my head I think of Dorothy Sayers, Georges Simenon, Eric Ambler, and Janwillem Lincoln van de Wetering as some I read repeatedly. The only ones I have on my Kindle at the moment are a few of Dorothy Sayers and Georges Simenon. But Icelandic is definitely intriguing me!
