The Baker Street peculiars

"It's a lovely day in 1930s London, right up until a giant stone lion comes to life and starts wrecking the city! It seems like the perfect case for the world's most famous detective, Sherlock Holmes. Of course, Sherlock Holmes doesn't actually exist; he is a fictional character created by Mrs. Hudson, who has been the real Baker Street detective all along, writing Holmes' adventures under the pen name of John Watson and running around the city in disguise. With an overwhelmed caseload she'll need the help of a precocious bunch of young detectives-in-training to solve the mystery of the living statues."--Provided by publisher.
