I did not at once answer. I was gathering my papers together.

"And in the meantime," he proceeded, touching my bag, "you had better leave these here. We will lock them up in the safe at once. It is better than carrying them about London."

It certainly seemed so. I half laid down the bag on the table, but at that moment from the outer room a most peculiar sound caught my ears—a faint cackling cough! I think I concealed my start. I turned away as if considering Fagg's suggestion, which, to confess the truth, I had been on the very point of agreeing to. For it would have been a great relief to me to know that the papers were in safe custody. But now a flash of lurid light seemed to have transformed everything.

"I thank you," I replied. "I should be glad to be free from the responsibility of the charge, but I dare not let these out of my own hands till the agreement is formally signed."

The younger man's face darkened. He assumed a bullying tone.

"I don't know how it strikes you, Mr. Bluestone," he said, "but it seems to me that this young gentleman is going rather too far. Do you think your employers will be pleased to hear of your insulting us, sir?"

But the elder man smiled condescendingly, though with a touch of superciliousness. It was very well done. He waved his hand.

"Stay, my dear Mr. Fagg; we can well afford to make allowance. You will telegraph at once, no doubt, Herr Schmidt, and—let me see—yes, we shall receive the duplicates of Nos. 7 and 13 by first post on Thursday morning."

I bowed.

"Exactly," I replied, as I lifted the now locked bag. "And you may expect me at the same hour on Thursday morning."
