"Of what nature?" the captain asked swiftly.

"It is my opinion," Crawshay said deliberately, "that the result of the whole accumulated work of the German Secret Service, compiled since the beginning of the war by means of Secret Service agents, criminals, and patriotic Germans and Austrians resident in the States, is upon this ship."

"Hell!" the purser murmured, without reproof from his chief.

"It was believed," Crawshay continued, "that these documents, together with a letter of vital importance, were on the steamer which conveyed the personnel of the late German Ambassador to Europe. The steamer was delayed at Halifax and a more or less complete search was made. I was present on behalf of the English Embassy, but I did not join personally in the search. You have all heard that the seals of a tin chest belonging to a neutral country had been tampered with. The chiefs of my department, and the head of the American Secret Service, firmly believe that the missing papers are in that chest and will be discovered when the chest is opened in London. That is not a belief which I share."

"And your reasons, Mr. Crawshay?" the captain asked.

"First, because Hobson and I were decoyed to Chicago by a bogus telegram, evidently with the idea that we should find it impossible to catch or search this steamer. Secondly, because there is on board just the one man whom I believe capable of conceiving and carrying out a task as difficult as this one would be."

"Who is he?" the captain demanded.

"A very inoffensive, well-mannered and exceedingly well-informed individual who is travelling in this steamer under, I believe, his own name—Mr. Jocelyn Thew."

"Jocelyn Thew!" the captain murmured.

"Thew!" the purser repeated.
