Holmes deduces the threat from a sailing ship, urgently instructs Openshaw to comply with the demand by placing a decoy paper on the sundial, but tragically, Openshaw drowns near Waterloo Bridge that night, ruled accidental. Shaken yet resolute, Holmes identifies the perpetrators aboard the barque Lone Star, sends them mocking pips, and vows vengeance, though the ship vanishes in Atlantic gales, leaving the case hauntingly unresolved amid a tone of dread, urgency, and futile brilliance.

Holmes places an ad, meets the innocent Baker—who reveals buying the goose from the Alpha Inn's club—then traces the bird through a publican, a Covent Garden salesman, and confronts James Ryder, the hotel attendant who stole the gem, hid it in a wrong goose, and lost it to the market.
