The infamous thief Gilly the Ghost has been spotted several times around Trafalgar Square and Sherlock Holmes would like her schemes to be discretely observed. Holmes recruits you and a gang of street urchins: First, you need to find out what Gilly is up to. Then, you have to stop her plan from going ahead. This case is a mini demonstration scenario for Sherlock Holmes Consulting Detective and the new mechanisms in the Baker Street Irregulars set. This is a standalone game. It comes with an excerpt from the address book, map, and newspaper, and does not need any items from the base game.
