GUILT. ATONEMENT. REVENGE. Klara Walldeen was orphaned as a child and brought up by her grandparents on a remote Swedish island. She is now a political aide in Brussels - and she has just seen something she shouldn't: something people will kill to keep hidden. On the other side of the world, an old spy hides from his past. Once, he was a man of action, so dedicated to the cause that he abandoned his baby daughter to keep his cover. Now, alone and far from home, only his daily swims keep the ghosts at bay. Only the Swimmer can save Klara. But time is running out...
