The occasion is Queen Victoria's Diamond Jubilee Celebration, where Professor Herringbone's Gobi Desert dinosaur bones are to be displayed; the scenes are London Bridge, Piccadilly Circus, Trafalgar Square, and other London landmarks; and the all-canine cast is done up in proper Victorian attire. The plot has the bones mysteriously disappearing from the London docks and the Detective of London--pausing only for kippered herring here, cucumber sandwiches there, and a tasty snack of fish and chips--quickly fingering an Oxford scientist with ""some odd theory that dogs are all descended from wolves."" ""I need the bones to prove my theory,"" exclaims Dr. S. S. Beagle (why not H.M.S.?); but the Holmesian hero, assuring him that ""your theory will have its day,"" persuades him to return the skeletons--""just in the nick of time"" for the celebration. A gassy 2% solution of spoofy Victoriana.
