Ake Edwardson's SAIL OF STONE and ROOM NO. 10, originally published by Norstedts and selling over 5 million copies worldwide in 21 countries, to Bob Bender at Simon & Schuster, in a very nice deal, for publication in 2011 and beyond, by Peter Riva at International Transactions (world English).Penguin US have recently published the first in the DCI Erik Winter series, Death Angels and will publish The Shadow Woman in September, which I believe is book two in the series. Cover and blurb aren't available at the moment.
Both titles: Sail of Stone and Room No. 10 are Erik Winter books. Looking at Ake Edwardson's website (in Swedish) Sail of Stone is the sixth in the series and possibly Room No. 10 is the seventh.
