For two detectives who hardly have two nickels to rub together, a call from one of the world's richest men is not an everyday event. An insignificant piece of art by a recently deceased artist seemingly vanished from a billionaire's personal collection, and he wants Abe and Duff to figure out where it went and why it was taken. To complicate matters, just after the picture was stolen, an anonymous Internet rumor claimed the drawing contained a secret code pointing to the location of a hidden treasure. The world of modern art is a long way from their usual beat of adulterers, legal research, and the occasional murder, but the case is too intriguing to pass. If they're lucky, they'll be able to draw out the truth before they get painted in a bad light.
