The Barking Emporium — Philip Van Wulven

The great detective uncovers a convoluted conspiracy to conceal the cause of two fires, one of which results in the death of an elderly couple. Dr Watson records the fine details which lead to the exposure of the villains.
While engaged by a certain farmer to investigate a conflagration and possible arson, Sherlock Holmes and Dr Watson follow a trail of clues back and forth through London, out into the countryside, and up the Chiltern Hills.
Inspector Lestrade of the Metropolitan Constabulary is pleased with the results of their enquiries, and some commercial plans may be impeded.
