"The windows," Garth said, "or the fireplace?"
Marvin shook his head.
"The windows were scarcely open, and a fire burned in the fireplace. And, mind you, this was before Mr. Alsop had seen the woman. I mean, he had not suggested the vision to me. The same thing happened last night. That figure came searching and disappeared in the same impossible way. I knew I wasn't dreaming then. I spoke of it to Mr. Alsop. It frightens me. I want an explanation of that."
"Catch your enemies and you'll catch your ghost," Garth said drily. "I'd like a shot at both."
"What you want," the inspector said to Alsop and Marvin, "is protection for yourselves and your distinguished guests. What the police want is to catch these fellows red-handed. We'll try to fit the two things. Don't lose your nerve. Go ahead with your conference, and trust Garth to find out how your veiled woman gets in and out of the house and through locked doors. I should say if we find her we should have the brains of the conspiracy. There may be no danger for you to-night. We've only Brown's post card to go on. That looks serious, and I'll do my best to protect you. But you must give me every chance to nab these birds. This sort of thing's getting too bold. There's too much foreign propaganda in this country. It would please me to throw the fear of Uncle Sam into such people."
