The Phantom was silent for a time. There was a hint of deep thought in the lines around his eyes. His hand passed slowly across his beard, still gritty and tangled from his experience in the tunnel. Suddenly the muscles of his face twitched.

“Anything else in the papers, doctor?”

“Only the usual silly doings of a silly world.”

“I mean in connection with the murder. No new developments?”

“None whatever, except that the search for the Gray Phantom has been renewed with increased vigor. There is an interview with the police commissioner, in which that optimistic soul declares the rascal cannot have left New York and that he will surely be captured within the next few hours.”

The Phantom smiled amusedly, but there was a fog in his mind. Was it possible no one had yet discovered that a second murder had been perpetrated in the Sylvanus Gage house? With his own eyes the Phantom had seen the housekeeper’s face fade into the ashen hue of death, and it seemed incredible that the body had not been found.

“By the way,” remarked Doctor Bimble, as if carrying out the other’s train of thought, “I wonder what has become of Gage’s housekeeper. I walked over there this morning to see if I could do anything for the poor lady. The front door was unlocked, but Mrs. Trippe wasn’t about.”

It required a little effort on the Phantom’s part to keep his voice steady. “H’m. She has had quite a shock. Perhaps she is lying ill and helpless in some part of the house.”

“The same thing occurred to me, and so I looked in every room in the house. The lady was nowhere in sight, however. Naturally she found it unpleasant to live alone in the place after the murder. She may have gone away for a visit.”

“Yes, quite likely.” It was on the Phantom’s tongue to tell what he had seen, but for a reason not quite clear to himself he desisted. Doctor Bimble’s revelation was somewhat staggering, and the disappearance of the housekeeper’s body was a poser that baffled the Phantom’s astuteness. The mystery seemed to grow more tangled and intricate with every passing hour, and he felt that, so far, his progress had been dishearteningly slow. Yet, with the whole city and its environs converted into a vast man trap, what could he do?
