Holmes returns to Woking, not having given up, but having to report that no treaty has turned up yet. Meanwhile, something interesting has happened at Briarbrae: someone tried to break in during the night, into Phelps's sick-room, no less. Phelps surprised him at the window but could not see his face through the hooded cloak that he was wearing. He did, however, see the interloper's knife as he dashed away. This happened the very first night that Phelps felt he could do without the nurse.
