"Hush, mother! I'm goin' out with Hackler in my boat. He's the man from Dartmoor, on the lookout for the escaped prisoner. I'm rowin' him out to the tramp; she's put back again." She smiled; she knew all about it. "Tell him not to stir out of that room until I comes home. He'll sleep a good while. He must not come out, not even in here--you understand, mother?" "Yes, but who is he?" "He's the man Hackler's after; the man who strangled the bloodhound. He knows our Bill. He's a gentleman; he'll do what he can for him when he's proved his innocence. He is----" "Come on, Brack; don't be all day," called Hackler. "I'll see to him, lad, never fear; he's safe with me," said his mother. "Comin'," said Brack as he went out and joined him. CHAPTER VII A CRITICAL MOMENT "Brack, as I remarked before, you are a smart fellow. Were you putting me off the scent when you said the man I am looking for went off in the tramp?" said Hackler. "I never said he were the man; I said there were a man went off with the boat's crew to the tramp." "I gave a description of him." "It seemed like him to me," said Brack. They reached the harbor; Brack pulled in his boat; Hackler stepped in and was rowed toward the tramp. The dirty looking steamer was farther out than anticipated, and Brack took his time; his practiced eyes discerned something invisible to Hackler. "Steam up," said Carl. "Most likely she'll be going in an hour or two." "I wonder what she put back for?" said Hackler half to himself. "Short o' coal," grinned Brack. "Shut up and don't be a fool," growled Carl. Brack could see the steamer as he looked sideways over his shoulder. A humorous smile stole over his face. "She's movin'," he thought. There was a stir at the stern of the tramp, the screw revolved, she was steaming away, and Carl Hackler was too late. When he recognized this he lost his temper; he had taken his journey for nothing. Catching sight of Brack's face, he fancied he detected laughter there; this did not improve matters. "Confound you, I believe you knew she was going!" he said angrily. "Not until the screw turned," said Brack. Hackler stood up in the boat and waved; some one on the tramp answered the signal but she continued on her way. "D----n the fellow, why doesn't he stop!" raged Carl. "Looks suspicious, but he doesn't know who you are. If he did he'd be sure to slow down," said Brack. Carl turned round quickly; he had an idea he was being chaffed and didn't like it. He stumbled, barked his leg on the seat, fell forward, and sprawled in the bottom of the boat. He did not know a sudden spurt by Brack caused this. He floundered about, smothered his rage as best he could, then ordered Brack to row him back. "Hope yer not hurt," said Brack sympathetically. No answer was vouchsafed to this polite inquiry. "Looks as though he might be aboard that tramp," said Brack. "They got off pretty sudden; perhaps you were recognized."
