It is the spring of 1912 and Dr. Watson has decided to retire from practice. In order to rekindle his old friendship with Sherlock Holmes, Watson travels to Sussex for a short holiday. But within hours of his arrival, Watson finds himself drawn into a series of terrible events, surrounding the apparent death of Holmes’s brother, Mycroft, the mysterious kidnapping of a London safe-maker and the murderous attack upon a seaman.
All these events are interrelated and Sherlock Holmes has to discover what lies at the root of it all, be it in London or Rome. The adventure continues in Russia in the companion to this volume, Sherlock Holmes & the Bolshevik Plot.
