“They’re frightened,” he decided; “they have grown suspicious. They never knew at what minute they would be pounced on. Their plot was clear enough. What they wanted to do was to palm me off as the Crown Prince of Budavia and put me on the throne when the King dies, as he is going to, if he has not already.”

“What rot!” exclaimed O’Hara. “Have you gone clean daft? What would be their object? How could they hope to do it?”

“I don’t know anything about their object,” Grey continued, calmly; “that’s still a puzzle to me; but they might hope for a lot with me in the condition I was in a few days ago. I apparently did their bidding to their utmost satisfaction.”

“It’s very improbable,” the Irishman insisted; “you’ll never be able to make any one believe it.”

“Won’t I?” the American demanded. “Well, then, wait and see. I’ve learned a lot since I saw you last. As much as I’ve told you is very plain. I have witnesses to prove it. And the other proofs—my God! What do you suppose has become of that box at the Gare du Nord? I sent Lutz for the check or receipt last night, and he never brought it. And this ring!” he went on, talking more to himself than to his companion, “it was in that box. Of course it was. And—” He ceased speaking—his thoughts were coming now too rapidly for words—and stood with lips pressed and eyelids drawn, gazing through his lashes into space.

He was satisfied that someone—he suspected it was Lutz—had got the box from the railway station, had rifled it, had abstracted the ring, had made so bold as to wear it. Yes, when Lutz had come in answer to his summons of the previous evening, he was wearing it even then. It must have been too large for him. He had been nervous, his hands had been twitching, and it had dropped from his finger, and—but no; could it be possible? Was it—was it Lutz who had returned in the early morning with intent to smother him? Was it he with whom he had wrestled? Was it from his hand that he had stripped this heirloom of the Budavian Court? And Lindenwald’s assurance that it bore the von Einhard arms? What could that mean, other than that Lindenwald was in league with Lutz and striving to shield him? And now their flight....

“Will you kindly tell me whether you are subject to these attacks?” asked O’Hara, interrupting his train of thought. “If I’m to be your lieutenant and serve in your campaign, it strikes me that I should have your full and entire confidence, and yet you are keeping something from me.”

“I’ll tell you everything after dinner,” Grey consented. “We’ll have a council of war and we’ll map out a plan of action.”

When O’Hara had run away to dress, promising to meet Grey and the Fraülein in a private room of the Café Riche at seven-thirty and dine with them, the American’s thoughts reverted to his resolution to see Hope Van Tuyl at all hazards. The disappearance of Lindenwald and the others, however, had again somewhat altered the situation. It was now more than ever necessary that he retain his freedom in order to track and run down the fugitives, and he recognised the risk he took in going to a hotel patronised largely by Americans and sending up a card bearing his real name. Once more his judgment was in the ascendency—wisdom had gained a slight advantage over the little blind god.

Sitting down at his table Grey took up a pen and wrote:
