Holmes sends Watson a telegram at about 10:45 AM to invite him to Boscombe Valley, if he has a couple of days to spare for the mystery. For once, Watson is hesitant to neglect work, and his wife has to convince him to go. She says that Anstruther would take his medical practice for him. It is unclear if Anstruther is the same as Jackson, who was the neighbour doctor in CROO. Leaving breakfast, Watson soon packs a bag and meets Holmes at the train station at 11:15 AM. Holmes is glad to see him, and he didn't already purchase both their tickets, so I guess he didn't assume Watson would come. At least he was aware that 30 minutes is not much notice, though it is more notice than he gives Watson in other cases. They ride the train together and discuss the case.
