Nora, who had clearly noticed the same symptoms, nodded approvingly. Alsop flushed and glanced at Marvin. The secretary knocked the ashes from his cigarette. The trembling of his fingers was more apparent.
"You should tell that by all means, Mr. Alsop," he said in a low voice. "That's what I want to find out. If I don't get some explanation of that I'll doubt my sanity."
Alsop cleared his throat.
"A ghost story," he said with an attempt at a laugh. "Fact is, Marvin and I and some of the servants are haunted by a veiled woman."
Nora came closer. The inspector turned back to the fire a little contemptuously. But Garth had no doubt that this hard-headed business man was serious.
"Go on," he said softly. "You think this ghost is connected with a dangerous conspiracy against you?"
"I can only tell you facts and let you judge," Alsop answered. "I daresay you know about my house on the river near the city line. It is lonely for that neighbourhood, and very old. I've always heard stories about a ghost, a veiled woman on the upper floor—some connection with the suicide of a beautiful girl long ago. You know the sort of thing. It's always told about old houses. The point is, I saw that veiled woman last night, and she gave me rather too much evidence of spirituality."
"Why do you connect a ghost with anarchists?" the inspector demanded.
"Because," Alsop answered, perfectly seriously, "I believe the thing was after my papers."
Garth laughed outright.
