"Nothing? I don't understand. They must have heard that they had been there anyhow."

"They discovered nothing. You do not understand the significance of this. I do! It means that I was mistaken for one thing. Their disappearance has more in it than the usual significance. Evil may have come to them, but not the ordinary sort of evil. Listen! You say that the police have disappointed you in having discovered nothing. That is no longer extraordinary to me. The police, or those who stand behind them, are interested in this case, and in the withholding of information concerning it."

"You are talking riddles to me, Spencer," Duncombe declared. "Do you mean that the police in Paris may become the hired tools of malefactors?"

"Not altogether that," Spencer said, waving aside a dish presented before him by the head waiter himself with a gesture of approval. "Not necessarily malefactors. But there are other powers to be taken into consideration, and most unaccountably your two friends are in deeper water than your story led me to expect. Now, not another question, please, until you have tried that sauce. Absolute silence, if you please, for at least three or four minutes."

Duncombe obeyed with an ill grace. He had little curiosity as to its flavor, and a very small appetite at all with the conversation in its present position. He waited for the stipulated time, however, and then leaned once more across the table.

"Spencer!"

"First I must have your judgment upon the sauce. Did you find enough mussels?"

"Damn the sauce!" Duncombe answered. "Forgive me, Spencer, but this affair is, after all, a serious one to me. You say that your two scouts, as you call them, discovered nothing. Well, they had only one evening at it. Will they try again in other directions? Can I engage them to work for me? Money is absolutely no object."

Spencer shook his head.

"Duncombe," he said, "you're going to think me a poor sort of friend, but the truth is best. You must not count upon me any more. I cannot lift even my little finger to help you. I can only give you advice if you want it."
