Publisher's Synopsis
"In the west end of London, an apparently crazed individual is on the loose, breaking into art galleries and private homes to slash valuable paintings of women. Despite Scotland Yard's best efforts, the criminal remains at large and continues on his destructive path. When Joanna and the Watsons are called in to solve the mystery, they soon discover that although the canvases have been slashed, their backings remain pristine, with no cuts or scratches. The criminal, it seems, is no mere vandal-he's searching for something hidden behind the portraits.
