The Hound of the Baskervilles has returned and we need Sherlock to help us solve the puzzle. There is evidence that a hound has learned how to knock over a waste food caddy and a pot of paint. This time the pooch has left a trail which means he or she could be caught red-handed, or should that be white-pawed? If you suspect who it is, please let us know and we'll pass on the details. Anybody seen a white-pawed canine?
