“All right,” he said affably. “I'll see you at the train. I'll walk about a bit.”

He turned and started back up the street again, walking idly. His chagrin was very real. He hated to be fooled, and fooled he had been. Gregory was not the only one who had lost a night's sleep. Then, unexpectedly, he was hailed from the curbstone, and he saw with amazement that it was Dick Livingstone.

“Take you anywhere?” Dick asked. “How's the headache?”

“Better, thanks.” Bassett stared at him. “No, I'm just walking around until train-time. Are you starting out or going home, at this hour?”

“Going home. Well, glad the head's better.”

He drove on, leaving the reporter gazing after him. So Gregory had been lying. He hadn't seen this chap at all. Then why—? He walked on, turning this new phase of the situation over in his mind. Why this elaborate fiction, if Gregory had merely gone in, waited for ten minutes, and come out again?

It wasn't reasonable. It wasn't logical. Something had happened inside the house to convince Gregory that he was right. He had seen somebody, or something. He hadn't needed to lie. He could have said frankly that he had seen no one. But no, he had built up a fabric carefully calculated to throw Bassett off the scent.

He saw Dick stop in front of the house, get out and enter. And coming to a decision, he followed him and rang the doorbell. For a long time no one answered. Then the maid of the afternoon opened the door, her eyes red with crying, and looked at him with hostility.

“Doctor Richard Livingstone?”

“You can't see him.”
