“If you only knew what I know now!” muttered Piper, as he turned down Willow Street.

[CHAPTER XII—DREAD.]

Much to his disappointment, Billy Piper was not permitted to see Roy Hooker. At the door Roy’s mother, who was plainly in a deeply distressed and anxious state of mind, told him that the doctor had given orders that Roy was not to be disturbed and had administered a mild opiate to quiet the unfortunate lad, who had grown fearfully excited when questioned concerning the cause of his injury.

“It’s a dreadful thing, Billy Piper,—a dreadful thing!” she exclaimed. “I don’t know why any one should hurt my poor boy like that. Some one must have done it. It was a wicked thing—a wicked, wicked thing! What if he never recovers? What if he is always wrong in his head? He doesn’t seem to remember anything, and maybe he never will.”

“It can’t be as bad as that, Mrs. Hooker,” said Billy, in an effort to cheer her up. “We—I talked with the doctor a short time ago, and he seems to think Roy will come round all right very soon. Don’t you think he fell, or something, and hurt himself that way?”

“How could he fall and hurt his face and the back of his head at the same time? I’m sure some one struck him, and it was a wicked blow. But we’ll find out who it was; such things always come out in time. You know all the boys, Billy Piper. Do you know anything about it? Have you heard anything?”

“Of course not, Mrs. Hooker,” answered Piper, feeling cheap and mean and miserable. “Do you think I wouldn’t tell you if I knew anything?”

“Not unless—— Oh, but of course you weren’t concerned in it. But perhaps you can find out, Billy. Roy says you’re a real wonder at finding out anything you want to know, and we all remember how you and Roy caught one of those bank robbers. Roy gave you all the credit. He said that you tracked the man, and that you even knew all about Fred Sage’s brother being alive before any one else was aware of it. Now, if you can do things like that, why can’t you find out who hurt my boy? The scoundrel who did it should be punished. Won’t you try to find out the truth and tell us about it?” Entreating him thus, she placed her hand on his shoulder, and it was with the greatest difficulty that he refrained from shrinking beneath her touch.

“I’ll do all I can,” he promised in a low tone. “I’m awful sorry this happened, Mrs. Hooker, but, believe me, I can’t really think any one hurt Roy maliciously and with deliberate design. It must have been an accident.”

“If it was that, wouldn’t the person who did it come forward and own up?”
