The continuing adventures of Marty Gold, the thirtyish, single, Jewish pharmacist on Manhattan's West Side. This time Marty is looking forward to attending a convention of jazz enthusiasts in Washington, D.C. The only fly in the ointment is Mase O'Dwyer, a thirteen-year-old pain-in-the-neck freaked out on magic tricks, which he performs badly, who cons Marty into schlepping him along so that he can take in a magic convention also being held in the nation's capital. Mase continues to con lots of people, eventually conning himself into getting kidnaped. And, as it turns out, Marty's Jewish sense of guilt spurs him on to track down the criminal. While it isn't exactly done with mirrors, the scheme does involve some magic, more than a little unscupulousness, and quite a bit of danger -- especially to Marty Gold!
