“What do you think of that, Holmes?” I had read the account aloud to him, while he finished his breakfast.

“My dear Watson,” said he, as he rose from the table and paced up and down the room, “you are most long-suffering, but if I have told you nothing in the last three days it is because there is nothing to tell. Even now this report from Paris does not help us much.”

“Surely it is final as regards the man's death.”

“The man's death is a mere incident—a trivial episode—in comparison with our real task, which is to trace this document and save a European catastrophe. Only one important thing has happened in the last three days, and that is that nothing has happened. I get reports almost hourly from the Government, and it is certain that nowhere in Europe is there any sign of trouble. Now, if this letter were loose—no, it can't be loose—but if it isn't loose, where can it be? Who has it? Why is it held back? That's the question that beats in my brain like a hammer. Was it, indeed, a coincidence that Lucas should meet his death on the night when the letter disappeared? Did the letter ever reach him? If so, why is it not among his papers? Did this mad wife of his carry it off with her? If so, is it in her house in Paris? How could I search for it without the French police having their suspicions aroused? It is a case, my dear Watson, where the law is as dangerous to us as the criminals are. Every man's hand is against us, and yet the interests at stake are colossal. Should I bring it to a successful conclusion it will certainly represent the crowning glory of my career.

Put on your hat, Watson, and we will stroll down together to Westminster.”
