“That is a bad sign.”

“On the contrary, I have noticed that when he is off the trail he generally says so. It is when he is on a scent and is not quite absolutely sure yet that it is the right one that he is most taciturn. Now, my dear fellow, we can’t help matters by making ourselves nervous about them, so let me implore you to go to bed and so be fresh for whatever may await us to-morrow.”

I was able at last to persuade my companion to take my advice, though I knew from his excited manner that there was not much hope of sleep for him. Indeed, his mood was infectious, for I lay tossing half the night myself, brooding over this strange problem, and inventing a hundred theories, each of which was more impossible than the last. Why had Holmes remained at Woking? Why had he asked Miss Harrison to remain in the sick-room all day? Why had he been so careful not to inform the people at Briarbrae that he intended to remain near them? I cudgelled my brains until I fell asleep in the endeavour to find some explanation which would cover all these facts.

It was seven o’clock when I awoke, and I set off at once for Phelps’s room, to find him haggard and spent after a sleepless night. His first question was whether Holmes had arrived yet.

“He’ll be here when he promised,” said I, “and not an instant sooner or later.”

And my words were true, for shortly after eight a hansom dashed up to the door and our friend got out of it. Standing in the window we saw that his left hand was swathed in a bandage and that his face was very grim and pale. He entered the house, but it was some little time before he came upstairs.

“He looks like a beaten man,” cried Phelps.

I was forced to confess that he was right. “After all,” said I, “the clue of the matter lies probably here in town.”

Phelps gave a groan.

“I don’t know how it is,” said he, “but I had hoped for so much from his return. But surely his hand was not tied up like that yesterday. What can be the matter?”
