At eleven o'clock next morning my friend and I were walking up the famous yew avenue of Holdernesse Hall. We were ushered through the magnificent Elizabethan doorway and into his Grace's study. There we found Mr. James Wilder, demure and courtly, but with some trace of that wild terror of the night before still lurking in his furtive eyes and in his twitching features.

"You have come to see his Grace? I am sorry; but the fact is that the Duke is far from well. He has been very much upset by the tragic news. We received a telegram from Dr. Huxtable yesterday afternoon, which told us of your discovery."

"I must see the Duke, Mr. Wilder."

"But he is in his room."

"Then I must go to his room."

"I believe he is in his bed."

"I will see him there."

Holmes's cold and inexorable manner showed the secretary that it was useless to argue with him.

"Very good, Mr. Holmes; I will tell him that you are here."

After half an hour's delay the great nobleman appeared. His face was more cadaverous than ever, his shoulders had rounded, and he seemed to me to be an altogether older man than he had been the morning before. He greeted us with a stately courtesy and seated himself at his desk, his red beard streaming down on to the table.
