The Secret Files of Sherlock Holmes — June Thomson

This collection of stories, allegedly written by Doctor Watson, includes the tragic tale of Lord Deerswood's unwanted legacy, the account of the jealous contortionist, the affair of the beautiful housekeeper, the deadly doings of the costumed Russian, the Aladdin's Cave episode, and the extraordinary circumstances surrounding the deadly Sumatran rats. The discovery of these Sherlock Holmes cases - one of which reunites Holmes with brother Mycroft - represents a treasure trove for Baker Street devotees.
