Where does alan find a place for David to get well? why is this risky? How long is David recuperating?

Alan knocked on the door of the first house they came to in Balquidder, which was risky for him since some members of the town belonged to an opposing clan. Luckily the house belonged to a Maclaren, who had followed the Stewarts in 1746. David was given a bed and a doctor was quickly ordered. David rested at the Maclaren house for nearly a month.
