It's a delicious thought: somewhere, tucked away in a closet, or a store room near you, is something hugely valuable. A vase, an old coin, or even a picture, which could propel you to the front pages, or bankroll you through retirement, if only you can find it. The central character in the new comic novel "Headlong' makes such a discovery: a long lost masterpiece by the Flemish artist Breughel. He realizes the painting will make him a national hero if he can get it into a big museum, and probably quite rich too. The only problem: he finds it in his neighbours house. The resulting moral and artistic dilemmas spin increasingly out of control.
