Undermajordomo Minor by Patrick deWitt

Lucien (Lucy) Minor is the resident odd duck in the bucolic hamlet of Bury. Friendless and loveless, young and aimless, he is a compulsive liar and a melancholy weakling. When Lucy accepts employment assisting the majordomo of the remote, forbidding castle of the Baron Von Aux he meets thieves, madmen, aristocrats, and a puppy. He also meets Klara, a delicate beauty who is, unfortunately, already involved with an exceptionally handsome partisan soldier. Thus begins a tale of polite theft, bitter heartbreak, domestic mystery and cold-blooded murder in which every aspect of human behaviour is laid bare for our hero to observe.
