It took him only an hour to find Watson on his daily tracks. The man was as regular and unchangeable as a railway engine.
It took him fifteen minutes to enter Watson's study and go through his papers. Finances all in order. Work all in order. Patients doing well. Wife died recently. A shame.
It took him a day to find the right books so that he could point at Watson's wall and suggest that they would fit there nicely.
