Sherlock Holmes Investigates. The Affair of the Captive Mothers - Sherlock Holmes Investigates, #7

After much debate, both internal, and with certain persons involved, Dr. Watson has decided to publish an account which may give rise to considerable discussion, but which must, by the virtue of being factual, reduce some of the gossip and speculation concerning his family by marriage. Involvement in a shipwreck, capture by savage pygmies, and by Borneo pirates, is paired with a more domestic account of enslavement within the walls of a certain Institution in the city of London.
Some followers of the great detective, Sherlock Holmes, are not yet aware of the remarkable circumstances surrounding the family of Dr. Watson's wife, Mary. The understandable impulse to maintain silence on certain private matters must be weighed against the need to disclose the true course of events.
