"You are not afraid to speak out ?" "I--I don't know," said Dick.
"Then you confess that you do know who fired at your father ?" "I did not confess," said Dick slowly.

"I cannot say.

I only think I know." "Then who was it ?" No answer.
"Dick, I command you to speak," cried Mr Marston, catching his arm and holding him tightly.
"I don't know," said Dick.
"You do know, cried Mr Marston angrily, and I will have an answer.

No man's life is safe, and these proceedings must be stopped." For answer Dick wrested himself free.
"I don't know for certain," he said determinedly, "and I'm not going to say who it is I suspect, when I may be wrong." "But if the person suspected is innocent, he can very well prove it.
Ah, here is Tom Tallington! Come, Tom, my lad, you can help me here with your old companion." "No," cried Dick angrily, "don't ask him." "I shall ask him," said Mr Marston firmly.

"Look here, Tom; our friend Dick here either knows or suspects who it was that fired that shot; and if he knows that, he can tell who fired the other shots, and perhaps did all the other mischief." "Do you know, Dick ?" cried Tom excitedly.
"I don't know for certain, I only suspect," said Dick sadly.
"And I want him to speak out, my lad, while he persists in trying to hide it." "He won't," said Tom.
