"Ask him," returned the officer; and he pointed to a quiet-looking man in black a few steps away.
Horace Kelsey at once stepped up to the person indicated, Ralph beside him.
"We are interested in these prisoners," he said. "Will you tell me why they have been arrested?"
"I am not at liberty to say much just now——" began the man in black.
"Are they not the Westville post office robbers?" questioned Horace, eagerly.
"Ah! What do you know of that case?" and the quiet-looking man became interested at once.
Ralph told him what he knew in a few brief, well-chosen words. The man smiled.
"You have hit it on the head," he said. "They are the guilty parties. I am a post office detective, and have just run them down."
"And is Percy Paget as guilty as the rest?"
"He was drawn into the scheme by this Brady, who is a very smart fellow. Brady also drew in the other man, who was formerly a horse dealer in this city."
