Lord Ellingham remained silent for a moment, looking from one visitor to another. It was very clear to Viner that some train of thought had been aroused in him and that he was closely pursuing it. He fixed his gaze at last on the old lawyer. "Mr. Pawle," he said quietly, "have you any proof--undoubted proof--that Mr. Ashton did possess papers relating to my long-missing uncle?" "Yes," answered Mr. Pawle, "I have!" He pulled out the bundle of letters which he and Viner had unearthed from the Japanese cabinet. "This! It is a packet of letters written by the seventh Countess of Ellingham to her elder son, the Lord Marketstoke we are talking of, when he was a boy at Eton. Your Lordship will probably recognize your grandmother's handwriting." Lord Ellingham bent over the letter which Mr. Pawle spread before him. "Yes," he said, "I know the writing quite well. And--these were in Mr. Ashton's possession?" "We have just found them--Mr. Viner and I--in a cabinet in his house," replied Mr. Pawle. "They are the only papers we have so far been able to bring to light. But as I have said, we are convinced there were others--much more important ones!--in his possession, probably in his pocketbook." Lord Ellingham handed the letters back. "You think that this Mr. Ashton was in possession of a secret relating to the missing man--my uncle, Lord Marketstoke?" he asked. "I am convinced of it!" declared Mr. Pawle. Lord Ellingham glanced shrewdly at his visitors. "I should like to know what it was!" he said. "Your lordship feels as I do," remarked Mr. Pawle. "But now I should like to ask a question which arises out of this visit. As we approached your lordship's door, just now, we saw, leaving it, two men. One of them, my friend Mr. Viner immediately recognized. He does not know who the man is--" "Which of the two men do you mean!" interrupted Lord Ellingham. "I may as well say that they had just left me." "The clean-shaven man," answered Viner. "Whom Mr. Viner knows for a fact," continued Mr. Pawle, "to have been in Ashton's company only an hour or so before Ashton's murder!" Lord Ellingham looked at Viner in obvious surprise. "But you do not know who he is?" he exclaimed. "No," replied Viner, "I don't. But there is no doubt of the truth of what Mr. Pawle has just said. This man was certainly with Mr. Ashton at a tavern in Notting Hill from about nine-thirty to ten-thirty on the evening of Ashton's death. In fact, they left the tavern together." The young nobleman suddenly pulled open a drawer in his desk, produced a box of cigarettes and silently offered it to his visitors. He lighted a cigarette himself, and for a moment smoked in silence--it seemed to Viner that his youthful face had grown unusually grave and thoughtful.
