A very patient man was that inspector in the cab, for it was a weary time before I rejoined him. His face clouded over when I showed him the empty box.

“There goes the reward!” said he, gloomily. “Where there is no money there is no pay. This night’s work would have been worth a tenner each to Sam Brown and me if the treasure had been there.”

“Mr. Thaddeus Sholto is a rich man,” I said. “He will see that you are rewarded, treasure or no.”

The inspector shook his head despondently, however. “It’s a bad job,” he repeated; “and so Mr. Athelney Jones will think.”

His forecast proved to be correct, for the detective looked blank enough when I got to Baker Street and showed him the empty box. They had only just arrived, Holmes, the prisoner, and he, for they had changed their plans so far as to report themselves at a station upon the way. My companion lounged in his arm-chair with his usual listless expression, while Small sat stolidly opposite to him with his wooden leg cocked over his sound one. As I exhibited the empty box he leaned back in his chair and laughed aloud.

“This is your doing, Small,” said Athelney Jones, angrily.

“Yes, I have put it away where you shall never lay hand upon it,” he cried, exultantly. “It is my treasure; and if I can’t have the loot I’ll take darned good care that no one else does. I tell you that no living man has any right to it, unless it is three men who are in the Andaman convict-barracks and myself. I know now that I cannot have the use of it, and I know that they cannot. I have acted all through for them as much as for myself. It’s been the sign of four with us always. Well I know that they would have had me do just what I have done, and throw the treasure into the Thames rather than let it go to kith or kin of Sholto or of Morstan. It was not to make them rich that we did for Achmet. You’ll find the treasure where the key is, and where little Tonga is. When I saw that your launch must catch us, I put the loot away in a safe place. There are no rupees for you this journey.”

“You are deceiving us, Small,” said Athelney Jones, sternly. “If you had wished to throw the treasure into the Thames it would have been easier for you to have thrown box and all.”

“Easier for me to throw, and easier for you to recover,” he answered, with a shrewd, sidelong look. “The man that was clever enough to hunt me down is clever enough to pick an iron box from the bottom of a river. Now that they are scattered over five miles or so, it may be a harder job. It went to my heart to do it, though. I was half mad when you came up with us. However, there’s no good grieving over it. I’ve had ups in my life, and I’ve had downs, but I’ve learned not to cry over spilled milk.”
