"My friend says that there were ninety-three stones, all rubies and sapphires; they were of exquisite lustre and extraordinary size. Possibly they might have been worth anything from a hundred and seventy thousand pounds to a quarter of a million."

I opened my eyes on hearing this. Were the men telling me the truth? I asked myself, or were they trying to interest me in the case by exaggerating the value of the treasure?

"What you say is almost incomprehensible," I continued. "I trust you will forgive me, but can you substantiate what you say?"

"When we say that we are willing to pay your expenses in advance if you will try to find the man, I think we are giving you very good proof of our bona fides," he remarked. "I am afraid we cannot give you any other, seeing as I have said, that we are both poor men. If you are prepared to take up our case, we shall be under a life-long gratitude to you, but if you cannot, we must endeavour to find some one else who will undertake the task."

"It is impossible for me to decide now whether I can take it up or not," I said, leaning back in my chair and looking at them both as I spoke. "I must have time to think it over; there are a hundred and one things to be considered before I can give you a direct reply."

There was silence for a few moments, and then Kitwater, who had been holding his usual mysterious communications with his friend, said—

"When do you think you will be able to let us have an answer?"

"That depends upon a variety of circumstances," I replied. "It is a matter difficult to average. In the first place there is no knowing where the man is at present: he may be in London; he may be in America; he may be in any other portion of the globe. It might cost five hundred pounds to find him, it might cost five thousand. You must see for yourselves how uncertain it all is."

"In that case we should be prepared to give security for the first-named amount, or pay you half in advance," Kitwater replied. "I hope you do not think, Mr. Fairfax, that we are endeavouring to play you false? You can see for yourself that our injuries are permanent, and, as far as they go, are at least evidence concerning the truth of our story. You can also see for yourself how this man has behaved towards us. He has robbed us of all we hold valuable, and to his act of treachery we owe the mutilations we have suffered. Can you wonder that we are anxious to find him?"

"I do not wonder at that at all," I said. "My only feeling is that I must regard it as an entirely business matter."
