'I must go down there, Watson. I must,' said Sherlock Holmes at the breakfast table on Thursday morning. 'Go? Go where?' I asked. 'To Dartmoor -- to King's Pyland.' 'Ah! So that's it,' I said. 'Well, everybody in the country is talking about the case at King's Pyland.' I always know when Holmes is interested in a case. He reads all the newspapers, he walks up and down, up and down the room, and does not speak for hours.
