The Adventure of Silver Patch

Yesterday morning, the famous throughbred horse, Silver Patch, and his trainer, Oscar Switt, were found dead in the horse's stall at the Cosgrove Stables.

The horse had been poisoned; and the trainer had been hit over the head and stabbed repeatedly with a sharp object.

Silver Patch, so named for the patch of silver hair on his mane, was owned by Sir Reginald Cosgrove, a breeder who also owns four other horses.

Persons routinely questioned by Inspector Gregson of Scotland Yard include Sir Reginald Cosgrove and his petite wife, Hilda Cosgrove; the Cosgrove cook, Mrs. Maggie Doan; Mrs. Doan's husband, house painter Henry Doan; and rival horse breeder Sir Archibald Baxter. Scotland Yard is also looking for one Bobby Jansen, a stable boy who left the Cosgrove's employ unhappily about a month ago.

The only clues discovered at the scene of the crime were some broken pieces of glass from the bottom of a beer bottle, and a pawnbroker's ticket.

Unable to develop a solid lead, Inspector Gregson has come to 221B Baker Street to consult with the master detective.
