It is an open secret that the credit of this smart capture belongs entirely to the well-known Scotland Yard officials, Messrs. Lestrade and Gregson. The man was apprehended, it appears, in the rooms of a certain Mr. Sherlock Holmes, who has himself, as an amateur, shown some talent in the detective line, and who, with such instructors, may hope in time to attain to some degree of their skill. It is expected that a testimonial of some sort will be presented to the two officers as a fitting recognition of their services.
