The Adventure of the Kidnapped Infant

The two-month-old daughter of the Duke and Duchess of Crescentshire has been kidnapped. Nanny Ann Whiston, who was taking the baby for a walk in the Park, says that a man accosted her, grabbed the baby from its carriage and disappeared in the direction of the Chemist.

After five days, the Duke and Duchess have still not heard from the kidnapper. The Duke, who wanted a son and was quite disappointed when he learned that his first born was a girl, has done nothing more about the kidnapping than to draw it to the attention of Scotland Yard.

Based on the description provided by Nanny Whiston, Scotland Yard has identified three chief suspects from its file of known kidnap specialists. The suspects are Anton Aldred, Jeremy Bridges, and Bill "Stonewall" Jackson. Aldred and Bridges kidnap strictly for ransom money, whilst Jackson specialises in selling babies on the black market.

Completely distraught over the strange disappearance of her daughter, the Duchess of Crescentshire has come to 221B Baker Street for help.
