Killing commendatore

When a thirty-something portrait painter is abandoned by his wife, he holes up in the mountain home of a famous artist. The days drift by, spent painting, listening to music and drinking whiskey in the evenings. But then he discovers a strange painting in the attic and unintentionally begins a journey of self-discovery that involves a mysterious ringing bell, a precocious thirteen-year old girl, a Nazi assassination and a haunted underworld.
