A Necessary Action — Per Wahloo

From Per Wahlöö -- co-author with his wife, Maj Sjöwall, of the internationally bestselling Martin Beck series of mysteries -- comes a suspense novel about a former German soldier wanted for questioning about a murder in Spain.

Willi Mohr--former German soldier, starving artist, enigmatic drifter--is arrested by the police and subjected to a lengthy and perplexing interrogation. Unwillingly, he is drawn back to the previous year he spent in Spain, the mysterious death of a Norwegian couple he shared a house with and his tireless attempts to discover how they died. As the interrogation intensifies, Mohr realizes that his own secret activities have implicated him in a dangerous political situation. Exhausted, at the end of his money, worn down by the police, he takes decisive action that leads to a profound personal release.
