“This companion,” Karl queried. “A dark, heavy fellow, was it?”

“No. Rather a pale man, blond. A—” Nikky checked himself.

But Karl was all suavity. “So,” he said, “while Niburg was unconscious the large man took the letter, which was sealed, magically opened it, extracted its contents, replaced them with—this, and then sealed it again!”

The King turned without haste to a drawer in his desk, and opened it. He was smiling. When he faced about again, Nikky saw that he held a revolver in =his hand. Save that the agent had taken a step forward, nothing in the room had changed. And yet; for Nikky everything had changed.

Nikky had been a reckless fool, but he was brave enough. He smiled, a better smile than Karl’s twisted one.

“I have a fancy,” said King Karl, “to manage this matter for myself. Keep back, Kaiser. Now, my friend, you will give me the packet of cigarette papers you carry.”

Resistance would do no good. Nikky brought them out, and Karl’s twisted smile grew broader as he compared them with the ones the envelope had contained.

“You see,” he said, “you show the hand of the novice. You should have thrown these away. But, of course, all your methods are wrong. Why, for instance, have you come here at all? You have my man—but that I shall take up later. We will first have the letter.”

But here Nikky stood firm. Let them find the letter. He would not help them. But again he cursed himself. There had been a thousand hiding-places along the road—but he must bring the incriminating thing with him, and thus condemn himself!

Now commenced a curious scene, curious because one of the actors was Karl of Karnia himself. He seemed curiously loath to bring in assistance, did Karl. Or perhaps the novelty of the affair appealed to him. And Nikky’s resistance to search, with that revolver so close, was short-lived.
