Plot hole: Holmes asks what had frightened Sir Charles enough to make him run away from the house. But when Dr. Mortimer described the scene, he only mentioned that at one point the prints did not show heel imprints. It is an easy deduction that sir Charles had been running, but the doctor did not say anything about the direction of the footprints.
