They were barely asleep, when another knock sounded.
“Don’t bother lighting a lamp, Henry. The professor is gone,” came Doctor Bogart’s voice.
“You mean—he died already, Doc?” asked Henry huskily.
“No, I mean he pulled out. Opened a window in the bedroom and left it open. Took all his clothes.”
“My goodness, Doc! Why, the man must be out of his head!”
“I wouldn’t swear to that, Henry—but he is out of my house.”
“Should we make a search for him—do you think—I hope you do not?”
“No, I don’t believe that would do any good, Henry. I just thought you’d like to know about it. Good-night.”
“Good-night, Doc.”
Doctor Bogart closed the door and Henry sank back.
