"Possibly those traces you speak of were not made at the time you specify. They may have been made since, or they may have been made before. Perhaps the Curator was curious and tried his hand at a little detective work on his own account."
"He hadn't the chance. Every portion of the building has been very thoroughly guarded since first we entered it. He may have gone up prior to the shooting. That is open to dispute; but if he had done so, why did he not inform us of the fact when he showed us the key? The Curator is the soul of honor. He would hardly deceive us in so important a matter."
The quick glance which this elicited from the Inspector awoke no corresponding flash in the eye of the imperturbable detective. He continued to shake his head over the small object he was twirling thoughtfully about between his thumb and finger, and only from his general seriousness could the Inspector gather that his mind was no more at rest than his fingers. Was this why his remark took the form of a question?
"Where was the Curator when you forced open that door behind the tapestry? Was he anywhere in the building?"
"No, sir; he has not been there to-day. He was ill last night, and he is ill to-day. He sent us his excuses. If he had been in the building, I doubt whether I would have given the order to burst open the door. I would simply have requested him to use his key. And he would have done so and kept his own counsel. I do not know as I can say as much for any of his subordinates. Happily, no spying eye was about at that time; and Stevens will be sure to see that he is not watched at his work if he has to lock the door upon the whole bunch of directors."
"This is to be a secret investigation, then?"
"I would so advise."
"With every reporter headed off, and anyone likely to report to a reporter headed off also?"
"Do not you advise this?"
"I do. Anything more?"
