The Phantom glanced at the grisly contents of the cabinets. A serio-comic grin wrinkled his face. “Aren’t you a bit hasty, doctor? I am not dead yet, you know.”

“True—quite true. But a man like you leads a precarious existence. If he doesn’t break his neck in some rash adventure the electric chair is always a menacing possibility. The chances are that I shall outlive you by a score of years. Promise that you will give the matter due consideration.”

The Phantom blinked his eyes. Doctor Bimble seemed amiable enough, yet the man was scarcely human. His whole being was wrapped up in his science and his entire world was composed of anthropological specimens and fine-spun theories.

“You wish me to make arrangements to have my body turned over to you after my death?”

“Precisely, Mr. Vanardy. That is what my friend and neighbor, Sylvanus Gage, did. An inferior personality, yet he had his points of interest. I am obliged to you for hastening his demise.”

A tremulous gasp sounded in the room. The Phantom turned, and his brow clouded as he noticed the expression of anguish that had crossed Helen’s face at the doctor’s words.

“You’re mistaken, Bimble,” he declared sharply; “I didn’t kill Gage. If I had done so, I should scarcely be here at the present moment.”

Doctor Bimble shrugged his shoulders. “The matter is of little consequence, my dear sir. Whether or not you killed Gage is not of the slightest interest to me. However,” with a significant glance at Vanardy’s mud-streaked clothing and begrimed features, “I am strongly of the opinion that you did. The only thing that perplexes me is that you are taking the trouble to deny it. Did I hear you say that you came here through the tunnel?”

“I did.” As he spoke the two words, the Phantom felt Helen’s eyes searching his face.

“Enough.” The anthropologist made a gesture expressive of finality. “Your admission that you came through the tunnel is an admission that you killed Gage. I perceive you do not follow me. Well, then, the circumstances of the crime prove conclusively that it was committed by someone who was aware of the existence of the tunnel. What the foolish newspapers refer to as astounding and miraculous is simplicity itself. The murderer entered Gage’s bedchamber by way of the underground passage and made his escape by the same route. Nothing could be simpler.”
