“We earned a living at this time by my exhibiting poor Tonga at fairs and other such places as the black cannibal. He would eat raw meat and dance his war-dance: so we always had a hatful of pennies after a day’s work. I still heard all the news from Pondicherry Lodge, and for some years there was no news to hear, except that they were hunting for the treasure. At last, however, came what we had waited for so long. The treasure had been found. It was up at the top of the house, in Mr. Bartholomew Sholto’s chemical laboratory. I came at once and had a look at the place, but I could not see how with my wooden leg I was to make my way up to it. I learned, however, about a trap-door in the roof, and also about Mr. Sholto’s supper-hour. It seemed to me that I could manage the thing easily through Tonga. I brought him out with me with a long rope wound round his waist. He could climb like a cat, and he soon made his way through the roof, but, as ill luck would have it, Bartholomew Sholto was still in the room, to his cost. Tonga thought he had done something very clever in killing him, for when I came up by the rope I found him strutting about as proud as a peacock. Very much surprised was he when I made at him with the rope’s end and cursed him for a little blood-thirsty imp. I took the treasure-box and let it down, and then slid down myself, having first left the sign of the four upon the table, to show that the jewels had come back at last to those who had most right to them. Tonga then pulled up the rope, closed the window, and made off the way that he had come.

“I don’t know that I have anything else to tell you. I had heard a waterman speak of the speed of Smith’s launch the Aurora, so I thought she would be a handy craft for our escape. I engaged with old Smith, and was to give him a big sum if he got us safe to our ship. He knew, no doubt, that there was some screw loose, but he was not in our secrets. All this is the truth, and if I tell it to you, gentlemen, it is not to amuse you,—for you have not done me a very good turn,—but it is because I believe the best defence I can make is just to hold back nothing, but let all the world know how badly I have myself been served by Major Sholto, and how innocent I am of the death of his son.”

“A very remarkable account,” said Sherlock Holmes. “A fitting wind-up to an extremely interesting case. There is nothing at all new to me in the latter part of your narrative, except that you brought your own rope. That I did not know. By the way, I had hoped that Tonga had lost all his darts; yet he managed to shoot one at us in the boat.”

“He had lost them all, sir, except the one which was in his blow-pipe at the time.”

“Ah, of course,” said Holmes. “I had not thought of that.”

“Is there any other point which you would like to ask about?” asked the convict, affably.
