When the Countess of Morcar's priceless blue carbuncle is stolen, a reformed thief is charged with the crime.

But a strange thing happens. Holmes tells Watson about Commissionaire Peterson's report of seeing a little knot of roughs assault a man carrying a Christmas goose home for the family. They all ran, leaving both the goose and the hat. No one could locate the man, so Peterson took possession - only for his wife to find Morcar's fabulous blue jewel inside the goose while preparing it! 

Can Sherlock Holmes sort this all out?
