He wanted to know the object of my inquiries, but I managed to satisfy his curiosity without telling him too much, for there is no reason why we should take anyone into our confidence. To-morrow morning I shall find my way to Coombe Tracey, and if I can see this Mrs. Laura Lyons, of equivocal reputation, a long step will have been made towards clearing one incident in this chain of mysteries. I am certainly developing the wisdom of the serpent, for when Mortimer pressed his questions to an inconvenient extent I asked him casually to what type Frankland’s skull belonged, and so heard nothing but craniology for the rest of our drive. I have not lived for years with Sherlock Holmes for nothing.

I have only one other incident to record upon this tempestuous and melancholy day. This was my conversation with Barrymore just now, which gives me one more strong card which I can play in due time.

Mortimer had stayed to dinner, and he and the baronet played écarté afterwards. The butler brought me my coffee into the library, and I took the chance to ask him a few questions.

“Well,” said I, “has this precious relation of yours departed, or is he still lurking out yonder?”

“I don’t know, sir. I hope to Heaven that he has gone, for he has brought nothing but trouble here! I’ve not heard of him since I left out food for him last, and that was three days ago.”

“Did you see him then?”

“No, sir, but the food was gone when next I went that way.”

“Then he was certainly there?”

“So you would think, sir, unless it was the other man who took it.”

I sat with my coffee-cup halfway to my lips and stared at Barrymore.

“You know that there is another man then?”

“Yes, sir; there is another man upon the moor.”

“Have you seen him?”

“No, sir.”

“How do you know of him then?”

“Selden told me of him, sir, a week ago or more. He’s in hiding, too, but he’s not a convict as far as I can make out. I don’t like it, Dr. Watson - I tell you straight, sir, that I don’t like it.” He spoke with a sudden passion of earnestness.

“Now, listen to me, Barrymore! I have no interest in this matter but that of your master. I have come here with no object except to help him. Tell me, frankly, what it is that you don’t like.”

Barrymore hesitated for a moment, as if he regretted his outburst or found it difficult to express his own feelings in words.

“It’s all these goings-on, sir,” he cried at last, waving his hand towards the rain-lashed window which faced the moor. “There’s foul play somewhere, and there’s black villainy brewing, to that I’ll swear! Very glad I should be, sir, to see Sir Henry on his way back to London again!”

“But what is it that alarms you?”

“Look at Sir Charles’s death! That was bad enough, for all that the coroner said. Look at the noises on the moor at night. There’s not a man would cross it after sundown if he was paid for it. Look at this stranger hiding out yonder, and watching and waiting! What’s he waiting for? What does it mean? It means no good to anyone of the name of Baskerville, and very glad I shall be to be quit of it all on the day that Sir Henry’s new servants are ready to take over the Hall.”

“But about this stranger,” said I. “Can you tell me anything about him? What did Selden say? Did he find out where he hid, or what he was doing?”

“He saw him once or twice, but he is a deep one and gives nothing away. At first he thought that he was the police, but soon he found that he had some lay of his own. A kind of gentleman he was, as far as he could see, but what he was doing he could not make out.”

“And where did he say that he lived?”
