“Cæsar’s ghost! What happened then? Is he dead?”

“Well,” answered Sleuth, “in my mind, at least, there is a doubt at this point. He is supposed to be dead. With two other prisoners, he broke out of Sing Sing in midwinter and tried to escape by crossing the Hudson on the ice. The other two convicts were both recaptured. The trio had separated immediately after getting out of the prison, and neither of the recaptured rascals knew what had become of Clarence Sage. For more than two months detectives sought everywhere for Sage, whose apparent success in avoiding them was both astonishing and perplexing. Eventually the body of a man was recovered from the river, but in such a condition that identification was difficult. There were reasons, however, to believe that the body was that of Clarence Sage. Andrew Sage viewed the remains and decided that it was his recreant son. The body was buried in Rutledge, and the grave is marked by a stone bearing the name of Clarence Sage.”

“Well, then, why do you doubt that he’s dead?”

Piper tapped his forehead. “I believe I’ve got a little gray matter up here,” he said boastfully. “After reading this letter, it took about thirty seconds for me to form a theory in which I have the utmost confidence. My conviction is that Clarence Sage is still alive. I think he did make good his escape and succeeded handsomely in baffling the officers who tried to follow him. The body that was taken from the river and buried under the name of Clarence Sage was that of some other man, as yet unknown. Perhaps it will continue to be unknown. When this identification and burial had taken place, danger for the escaped man was reduced to a minimum. Mind you, I’m not making the assertion that Andrew Sage knew the body was not that of his son, but what would be more natural than for him to identify it as such in order to give Clarence a better chance for freedom? Perhaps, at the time, he really believed it to be the unfortunate young man. Possibly, through some means, he has since learned that his son is alive.”

“If you hadn’t read so much detective stuff, such an improbable idea could not have found lodgment in your crazy garret,” said Hooker. “I understand you’ve even tried to write stories yourself lately. Say, Sleuth, if this matter wasn’t so serious, it would be laughable.”

“Your words,” returned Piper, “betray the narrow limits of your reasoning faculties. I’m not basing my suspicions on mere guesswork, Hooker.”

“Then, for the love of Mike, what do you base them on?”

“One week ago you met a stranger who behaved in a most peculiar manner. Apparently of some education and refinement, this man seemed to be somewhere near the age of Clarence Sage, if Sage still lives. He made inquiries of you concerning the Sages in Oakdale, and when he learned that Fred Sage was approaching he took to his heels and got away. He didn’t dare remain to face Fred in your presence. Why, Hooker—why? Simply because he knew that in his amazement Fred would call him by name and give the whole thing away. What do you think about that?”

For a moment or two Roy shook his head. “I don’t believe it. It can’t be true, Piper. If that’s all you have to base your belief on——”

“Did there seem to be anything especially wrong with Fred last night?”
