Martin sees a painting which he thinks may be a great missing masterpiece. What follows is a tense but hilarious rollercoaster ride as he attempts to discover the picture's origins and to acquire it by fair means or foul - well mostly foul, actually. Pacy and very funny (I laughed to the bottom of my boots) - it reads like a farce and keeps you guessing (and cringing) right until the last page. The stuff about art is pretty interesting too.
