Following a trail of clues at Aldgate station, Holmes makes a stunning discovery that leads to an unexpected twist in the investigation.

Now convinced that Cadogan West’s death is part of a greater international conspiracy, Holmes asks Mycroft to send him a list of all the foreign spies residing in London.

Soon, the master detective uncovers the most likely suspect but he needs proof — and the only way to get it is by orchestrating a daring break-in.
