“The biggest thing for years,” said Holmes. “We have two hours before we need think of starting. I think we might employ it in getting some dinner, and then, Lestrade, we will take the London fog out of your throat by giving you a breath of the pure night air of Dartmoor. Never been there? Ah, well, I don’t suppose you will forget your first visit.”
