I am amused to find myself reading an American, well, two American detective novels published in Great Britain as one paperback. You see, when someone in here said how great the Harry Bosch books by Michael Connelly are, and Steph seconded that by saying she just loved Harry, I immediately went to ThriftBooks and ordered the first six in the series, and these two were available this way. Yep, published in Great Britain! They call it a Bumper Omnibus Edition, and it is really, really fat and unwieldy, but I find I don't really mind all that much. Connelly is a good writer, and these books just sail right along.
So now I have two terrific detective heroes: Harry Hole (Jo Nesbo) and Harry Bosch. Even though he is in translation from the Norwegian, I think Nesbo is the better writer, but both can turn out dazzling plots.
Oh, the books are The Concrete Blonde and The Last Coyote.
