The Dogs of Riga

A raft adrift in Swedish waters holds a grisly cargo: two dead Latvians who have been horribly tortured. Arriving to investigate from Riga is an enigmatic police major, who disappears after reporting back to headquarters. When the major dies, Wallander goes to Riga and meets his widow, Baiba. Together, they become embroiled in a search for files that may document high-level corruption.
