A walker found the key caught between stones below the guesthouse. Corrosion obscured its number. When Tessa showed it to the owner, he produced a replacement-key receipt bearing the name of a guest who died the following winter.
The receipt included a small sketch of the lost key's bow. The guest had been embarrassed about dropping it and insisted on paying for a replacement, although the owner said the lock was already due to be changed. He had kept the receipt because the guest enclosed a thank-you note afterward.
Tessa contacted the family through the guesthouse's old correspondence. They recognized the sketch as the work of a man who drew everything he could not describe clearly. His granddaughter had inherited the habit and sent back a drawing of the recovered key.
The original remained with the guesthouse archive. The family wanted the sketch and the note, not a corroded object that no longer opened anything. Tessa had expected the key's mystery to end at a lock. Instead, it ended in a recognizable way of looking, passed from one person to another after the door itself had changed.
