"My son was," said Tortue calmly.

"And what sort of answer is that? 'Tis lucky for you Cap'en Roberts isn't aboard this shed. He wouldn't have understood that language, not he--and he wouldn't have troubled you for an explanation neither. Here's a fine thing, lads! If a man dies, his father, what's been lying in the lap of luxury at home, is to have his share. That's a nice new rule for gentlemen adventurers, and not content with his share, wants to set up for cap'en. I have a good mind to learn you modesty, Peter, just as Roberts would have learnt you."

He was talking quite smoothly, with a grin all over his face, but I never saw a man that looked so dangerous. Peter Tortue, however, was in no way discomposed.

"Why, you blundering fool," he answered, "where would you ha' been but for me? No, I wasn't on the Sierra Leone River with you, or you wouldn't be eating your hearts and your pockets empty upon Tresco. No, I am not your captain, or you wouldn't never have lost track of Cullen Mayle at Wapping."

There were four faces now alertly watching Peter Tortue, and the fourth was mine. It was not merely that my life hung upon his predominance, but there was the best of chances now that I might get to the bottom of the mystery of their watching.

"You talk of Roberts," he continued, "well you're not the only man that knew Roberts, and would Roberts have let Cullen Mayle slip through his fingers--at Wapping too? Good Lord, it makes me sick to look at you, George Glen!" and he turned to Roper, "Who was it found the track for you; was it him or me?" he cried. "Who was it found the nigger and sailed from the port o' London to Penzance, ay, and would ha' found out the nigger's message if he hadn't had the sickness on him. Was it him or was it me? Why the nigger knowed you all! Would he ha' sailed to Penzance on that boat if he had seen a face on board that he had known? not he."

"That's true," said Roper.

"Who brought you all to Tresco, eh? Who hindered you from rushing the house, ay, hindered you in the face of your captain, and a deal you'ld ha' found if you had rushed the house. A lot he knows, your captain. P'raps he thought Adam Mayle was the man to leave a polite note on his mantelshelf, telling us where to look. Who told you to wait for Cullen Mayle?"

"We have waited," answered Glen. "How long are we to wait? Where is Cullen Mayle?"

Peter Tortue threw up his hands.
