Mr. Blake nodded. "We'll find him," said he, "if it takes all night."

"Surely he cannot have sunk lower than this."

"Remembering his get-up I do not think so. Yet who knows? Some mystery lies back of his whole conduct. Dining in your home, with this to come back to! I don't wonder——"

But here a thought struck him. Pausing with his foot on the stair, he turned a flushed countenance towards Mr. Sedgwick. "I've an idea," said he. "Perhaps——" He whispered the rest.

Mr. Sedgwick stared and shook his shoulders. "Possibly," said he, flushing slightly in his turn. Then, as they proceeded up, "I feel like a brute, anyway. A sorry night's business all through, unless the end proves better than the beginning."

"We'll start from the top. Something tells me that we shall find him close under the roof. Can you read the names by such a light?"

"Barely; but I have matches."

And now there might have been witnessed by any chance home-comer the curious sight of two extremely well-dressed men pottering through the attic hall of this decaying old domicile, reading the cards on the doors by means of a lighted match.

And vainly. On none of the cards could be seen the name they sought.

"We're on the wrong track," protested Mr. Blake. "No use keeping this up," but found himself stopped, when about to turn away, by a gesture of Sedgwick's.
