Vanished? (Stockholm Sleuth, #1)

She: a very hot 30 something Swedish woman. He: a native of Berlin, on vacation in rural Sweden, seeking solace for his broken heart. They meet. He finds her irresistible. But before their relationship can get off the ground, she vanishes mysteriously, having apparently been abducted. So Martin sets out to rescue Liv from her captors, with the aid of two Swedish detectives in a race against time – and across Sweden. In so doing, Martin and his intrepid detective duo put their very lives on the line.

VANISHED? is the first book in the Stockholm Sleuth Series and where we meet the two private investigators, Elin and Lars. If you like fast action and surprising twists, then you'll love Christer Tholin's Swedish crime novels.
