'The Patrician Lady', a priceless painting, is coming from France on loan to Parnell's London gallery but, at its unveiling, there is an explosion and gun-shots, suggesting a robbery although it is all over in seconds. The painting is still in place but the name 'Zarchetti' is stamped on the back of the canvas, suggesting a switch. Since the real painting is presumed stolen, Parnell's girlfriend Bernice, a talented forger, makes several copies of the original which are palmed off as the original and offered to interested parties. But did 'The Patrician Lady' really leave the gallery?
