Its line in the clue was, "You know my methods Watson. Three Sevens lead to thirteen." 100 paces west of the entrance of the graveyard, there were graves of three Severns. In the direction of the headstones, thirteen nameless travellers were buried, and near their graves, there was a pile of stones, near which, the lead pipe cinch, that had the painting, was kept.
After John Silver had fled to California after smuggling the painting of the shepherdess, he started living in Ramos Sanchez's house. After getting an idea from the picture that was painted above the shepherdess' painting, Silver bought seven parrots with "pretty yellow heads" and seven cages. He then began teaching them their individual riddles.
