At the constant repetition of the threats he merely laughed: it was not the individual he feared, but the concerted whole. In his lightning trips he did not fail to notice the signs of the growing White menace, and so he said to Bela Kun, "Kill! Kill! Kill!" setting a good example. Yet his day was to come, and Szamuelly had a hint of it one morning when he received a letter addressed to him at the Batthyany Palace. He slit open the envelope. Inside was a plain post card on which were written six words only: Szamuelly shall die. THE WHITE KNIGHT Szamuelly felt a surge of murderous hate toward the sender, and sent for Gunzi. When the detective arrived Szamuelly handed over the card to the other. "Look, Comrade Gunzi, look! Here is another message which I have to-day received through the post." The detective took and inspected it with a quizzical eye. "He seems certain of himself," he muttered calmly. Szamuelly smashed his fist down upon the table before him. "Do you think I sent for you to hear that?" he shouted furiously, but to the acute ears of the detective there was an undercurrent of fear in the voice of the other. "Well, what do you want of me?" he asked coolly. "Is there still no trace of the braggart?" Gunzi shook his head, and his lips tightened. "Not yet, comrade. He is as elusive as a will-o'-the-wisp, yet I shall trace him in the end. At Aszod, had not Gonnard fled to Budapest, I should have arrested the White Knight, and by now he would be but a memory." "Bah, child's talk! Did you not arrest him here, in Budapest itself; did you not actually imprison him in a cell underneath Parliament House, and did not you and the fools on the Council let him free against my advice? I should have hanged that man whether he had been the White Knight or not." Gunzi bit his lip. "Who could have foreseen that the White Knight had such a cunning trick up his sleeve? That day in the Hapsburg Palace I would have sworn an oath it was not he." "Even now I do not understand. I cannot get Korvin-Klein to talk. Was it or was it not the White Knight who appeared before us that morning?" "It was. My men trailed him for a time, and then--he disappeared entirely. They reported to me. I hurried to the room where I had arrested him the night before and there I found a message from him thanking me for my help in his escape." "Yes, yes. All that I know. But what of his scars, the difference in his expression, in the man himself?" Gunzi shrugged his shoulders. "The White Knight could most easily tell you that. Myself, I have only a theory." "And that?" "I believe that the White Knight's scars were nothing but grease-paint. During the night he wiped them off." "Good God!" Even into Szamuelly's unwilling eyes there crept a glow of admiration, till suddenly he remembered the message he had just received, and shivered. "Gunzi, you must catch him soon. I begin to feel nervous."
