Having done this to his complete satisfaction, he sat and smoked and thought again. Three minutes after the time Clement had seen Siwash Mike enter the gluemaker’s, the telephone bell rang in Mr. Neuburg’s room. With one glance at the floor near the door he had just shut and bolted, he rose and answered the ring.

What he heard over the wire gave him apparently a pleasant surprise, for though his curiously impassive face showed no sign, he said, “Eh, but you have been quick, I did not expect you for a day or two.... No, say nothing now.... I will see you this night, about ten o’clock. And now listen——” And in his slightly purring voice he gave a string of directions. They were very guarded, for telephones have eavesdroppers, but quite explicit to understanding ears.

He hung up the telephone, dropped back into his chair again and thought and smoked. But after a perceptible minute this curious, immobile-faced man, allowed himself the luxury of a great laugh. It was a terrible laugh, but a short one. It was perhaps well it was so, for very quickly after there came the scratch at the communicating door, which betokened that Méduse Smythe had returned to her room, and was ready to serve him.

He sprang up at once, and again glancing at the floor by the other communicating door, let Méduse in. The woman said, “I have come back by myself. The girl wished to go for half an hour’s motor drive alone in the Battlefield Park.... No, the Englishman was not with her. She may be going to meet him, but I don’t think so.... The whole thing seemed a sudden thought on her part. Can I do anything?”

“You will,” he smiled at her with his mirthless grin. “This Seadon may be meeting her, but even if he is or isn’t, I want you to go down to the lobby, watch for him coming in, and when he comes in, come up here as swiftly as you can and tell me. No, do not telephone up. Come yourself. I need you....” She made a step to go. “When you join me in this room don’t be surprised at anything. When I say things to you, play up—play up, remember that.”

It seemed only a few minutes before she was back in the room. Mr. Neuburg came through the intercommunicating bathroom at the sound of the key in her door. He looked at her, indicating the necessity for quiet.

“He came in just as I reached the lobby,” she said. “He did not see me. He came up straight to his room, I think.”

Mr. Neuburg caught her by the wrist, and both very stealthily went back to his room. He led her close to the doors that communicated with Clement Seadon’s bathroom. He paused, listened. He could hear no sound from the Englishman’s side of the doors. He looked at her, grinned, and pointed to the floor near their feet.

On the floor was a yellow-painted lead pencil. It was lying alongside a white line Mr. Neuburg had chalked on the floor. The woman Méduse stared down at it, wondering what on earth it all meant.... And as she stared down the pencil began to move.
