The Hundred Year old man by Jonas Jonasson

Escaping through his bedroom window, into the flowerbed, Allan makes his getaway.  And so begins his picaresque and unlikely journey involving criminals, several murders, a suitcase full of cash and incompetent police.  As his escapades unfold, Allan's earlier life is revealed.  A life which remarkably, he played a key role behind scenes in some of the momentous events of the 20th century.
