Dad, Bess, and I are all set for London when Ned's Shakespeare professor asks us to do a simple favor: to take a look at his townhouse while we're there, since he can't seem to locate the housekeeper and fears something's wrong. Sounds easy enough, so I take the key. <P> Eager to cross the favor off our list, we stop by 53 Banbury Square shortly after we land. And let's just say things in the townhouse aren't quite tip-top. And the key? Well, it unlocks a Pandora's box of serious trouble.
