Pansy the poodle and her human friend Avery have solved mysteries all over the worldfrom foiling a jewel thief in Los Angeles to tracking down a talking monkey in New York. But their newest adventure may be the most important one yet. They have been summoned to Buckingham Palace by Queen Elizabeth herself to find Lily, one of her beloved Corgi puppies. As the two sleuths follow clues around London, they visit its most famous sights, from Big Ben to the Tower of London, to Selfridges Department Store. They learn what English people call hotdogs (bangers) and what they call policemen (bobbies). They even ride on the top of a double-decker bus. In the end, using their usual ingenuity and brainpower, Pansy and Avery solve the mystery, catch the dog thief, and return Lily to the Palace. The Queen throws a royal celebration and Pansy is once again reminded of the importance of friendship, forgiveness, and love.
