“I have sent a report from Grimpen to Princetown as to the death of Selden. I think I can promise that none of you will be troubled in the matter. And I have also communicated with my faithful Cartwright, who would certainly have pined away at the door of my hut, as a dog does at his master’s grave, if I had not set his mind at rest about my safety.”

“What is the next move?”

“To see Sir Henry. Ah, here he is!”

“Good-morning, Holmes,” said the baronet. “You look like a general who is planning a battle with his chief of the staff.”

“That is the exact situation. Watson was asking for orders.”

“And so do I.”

“Very good. You are engaged, as I understand, to dine with our friends the Stapletons tonight.”

“I hope that you will come also. They are very hospitable people, and I am sure that they would be very glad to see you.”

“I fear that Watson and I must go to London.”

“To London?”

“Yes, I think that we should be more useful there at the present juncture.”

The baronet’s face perceptibly lengthened.

“I hoped that you were going to see me through this business. The Hall and the moor are not very pleasant places when one is alone.”

“My dear fellow, you must trust me implicitly and do exactly what I tell you. You can tell your friends that we should have been happy to have come with you, but that urgent business required us to be in town. We hope very soon to return to Devonshire. Will you remember to give them that message?”

“If you insist upon it.”

“There is no alternative, I assure you.”

I saw by the baronet’s clouded brow that he was deeply hurt by what he regarded as our desertion.

“When do you desire to go?” he asked coldly.

“Immediately after breakfast. We will drive in to Coombe Tracey, but Watson will leave his things as a pledge that he will come back to you. Watson, you will send a note to Stapleton to tell him that you regret that you cannot come.”

“I have a good mind to go to London with you,” said the baronet. “Why should I stay here alone?”

“Because it is your post of duty. Because you gave me your word that you would do as you were told, and I tell you to stay.”

“All right, then, I’ll stay.”

“One more direction! I wish you to drive to Merripit House. Send back your trap, however, and let them know that you intend to walk home.”

“To walk across the moor?”

“Yes.”

“But that is the very thing which you have so often cautioned me not to do.”
