"And who is that?" she enquired.

"Jocelyn Thew."

"And why do you single him out?"

"Because," Crawshay told her patiently, "we had evidence in America to show that he was working with our enemies. It is true that he has not been associated to any extent with the German espionage system in America, but he has been well-known always as a reckless adventurer, ready to sell his life in any doubtful cause, so long as it promised excitement and profit. It was known to us that he had come into touch with a certain man in Washington who has been looking after the interests of his country in America. It was to shadow Jocelyn Thew that I came on this steamer. His friends cleverly fooled Hobson and me, and landed us in Chicago too late, as they thought, to catch the boat. That is why I made that somewhat melodramatic journey after you on the seaplane. Do please consider this matter reasonably, Miss Beverley. It was perfectly easy for him to slip across and place these things in your luggage as soon as he found that his original scheme was likely to go wrong. You were the one person on the steamer whom he reckoned would be safe from suspicion. You were part of his plot from the very first, and no more than that."

"I cannot believe this," she said slowly.

Crawshay's face darkened.

"It is no business of mine, Miss Beverley," he declared, "but if you will forgive my saying so, you must be infatuated by this man. The evidence is perfectly clear. You are a prominent citizeness of a great country, and you have been made an accessory to an act of treason against that country. Yet, with plain facts in my hands, it seems impossible for me to shake your faith in this person. What is the reason of it? What hold had he upon you that he should have induced you to leave your work and your home and betray your country?"

"He has no hold upon me at all," she replied indignantly. "Since you are so persistent, I will tell you the truth. I once saw him do a splendid thing, a deed which saved me from great unhappiness."

"There we have it then at last!" Crawshay exclaimed eagerly. "You are under obligations to him."

"I certainly am," she acknowledged.
