Robert raced off. Winter, who had not interfered hitherto, because Furneaux always had a valid excuse for his indiscretions, made as if he would follow and restrain the younger Fenley; but Furneaux caught his eye and winked. That sufficed. The Superintendent contented himself with gazing after Robert Fenley, who ran along the avenue until clear of the Quarry Wood, when he, too, plunged through the line of elms and was lost to sight.

Hilton watched his impetuous brother with a brooding underlook. He still held in his hand a leather portfolio bulging with papers, some of which he had placed there when Winter opened the door of the railway coach in St. Pancras station. The footman offered to relieve him of it, but was swept aside with a gesture.

"I have never known Robert so excited and erratic in his movements as he has been today," he said at last. "I hope he will not engage in a vulgar quarrel with this Mr. Trenholme, especially in Miss Manning's presence."

Apparently he could not quite control his voice, in which a sense of unctuous amusement revealed itself. Furneaux could not resist such an opportunity. He had pierced Robert's thick skin; now he undertook a more delicate operation.

"That would be doubly unfortunate," he said, chuckling quietly. "If I am any judge of men, Mr. Robert Fenley would meet more than his match in our artist friend, while he would certainly undo all the good effect of an earlier and most serious and convincing conversation with the young lady."

Hilton swung around on him.

"When did my brother return from London?" he asked.

"Shortly before five o'clock. He and Miss Manning had tea together, and afterward strolled in the gardens. I don't wonder at any artist wishing to sketch Miss Manning? Do you? If I may be allowed to say it, I have never seen a more graceful and charming girl."

"May I inquire if you have made any progress in the particular inquiry for which I brought you here?"

Hilton Fenley spoke savagely. He meant to be offensive, since the innuendo was unmistakable. Apparently Furneaux's remarks had achieved some hypodermic effect.
