Very slowly de Montville rose to his feet, and stood, holding to the back of his chair.

"I am—quite well," he said impressively.

"Very good, sir," said Holmes again, and withdrew, shaking his head dubiously as soon as he was out of the Frenchman's sight.

As for de Montville, he went slowly across to the window and, leaning against the sash, gazed down upon the empty street.

Not until he heard Mordaunt's step outside more than half an hour later did he move, and then very abruptly he returned to the writing-table and seized the pen anew. He was writing with feverish rapidity when Mordaunt entered.

Very quietly Mordaunt came up and looked over his shoulder. "My boy," he said, "I am very sorry, but that is not legible."

His tone was unreservedly kind, and Bertrand jerked up his head as if surprised.

He surveyed the page before him with pursed lips, then flashed a quick look into Mordaunt's face.

"It is true," he admitted, with a rueful smile. "I also am sorry."

"Leave it," Mordaunt said. "You are looking fagged, Yes, I mean it. It will keep."
