Until then he had been conscious of no especial emotion, and his course had been taken instinctively rather than with a definite purpose of effecting his escape; but instead of breathing free now that he was where for a time at least he could mingle with the passers unsuspected, a great fear came upon him. Throughout all the long journey he had nursed his awful purpose calmly and steadfastly, never for an instant wavering; now he seemed still to feel the handle of the dagger in his palm, he saw the blade flash as he poised it over Poubalov's heart, and he heard again the loud gasp with which the spy fell under the blow. Litizki trembled. His throat was parched, his skin hot, but dry as the dust on the pavement. He glanced furtively up and down the avenue, as if to see the policeman who would presently arrest him.

Litizki had paused, unable to walk without staggering, when he dropped so completely from heroism to trepidation. He grasped a trolley post for support and was dimly conscious that two or three girls who were passing laughed at him for being helplessly drunk. Half unconsciously he felt in his pocket and drew forth the revolver with which he had intended to kill the spy. Should he not end his misery then and there, and cheat the hangman? He looked down at the tiny barrel, so large in its tragic possibilities, and with the thought that he had but to exercise a steady hand upon himself as he had upon Poubalov in order to plunge into oblivion, he began to recover. The grated cover of a sewer basin was at his feet and he dropped the weapon upon it. It rebounded a very little and then slipped through the grating, out of sight and out of reach. Litizki instantly wondered why he had done that.

"That was unreasonable. The revolver was not evidence," he muttered, and then a wild joy surged in his heart as he reflected that he had accomplished his purpose.

"That was no crime in the light of reason," he argued. "The necessities of the situation demanded it, and though the law will say otherwise, I am content."

He was almost himself again now, and it flashed upon him that his work, after all, was but half done. There was one other step to be taken before his heroic deed could be of service to her whom he worshiped, and to his benefactor whom he idolized. Strobel must be freed, but how? Certainly not by standing there at the curb in plain view, waiting to be arrested. No; whatever be his ultimate fate, he must effect at least a temporary escape.

Once more steadied by a purpose to strive for, Litizki crossed the avenue and walked on in the same general direction until he came to Washington Street. His delay at the curb had been brief as measured by the watch. With every step he took his brain grew clearer. He saw the folly of going to Poubalov's lodging-house in Bulfinch Place for the purpose of releasing Strobel. His conviction that Strobel was confined there had not been shaken by any of the events since his failure to expose Poubalov's secret. News of the murder would undoubtedly be taken to that house before he could get there. The release must be effected by some other hand than his own; but what matter? He had made the release possible. Miss Hilman would ever give him credit for it, and that was enough, as undoubtedly she would tell Strobel how it came to pass.

His plan of operation was fully formed when he reached Washington Street. He boarded the first Chelsea ferry car that came along, and set himself to thinking of it. When the conductor touched his shoulder to remind him of his fare, he started violently as if the avenging hand of law had been laid upon him. There was a recurrence of the dreadful fear that had momentarily possessed him, and again he shook as if with an ague. He felt an almost irresistible impulse to jump from the car and run; and when at last he left it, near the far end of Hanover Street, he had not yet recovered. With great difficulty he dragged his steps through the crowded streets of the North End until he came to the house where Vargovitch lived. As he climbed the stairs, he felt his courage return; and when Vargovitch bade him enter, he was again the somber, depressed figure with which all his acquaintances were familiar.

"Vargovitch," he said directly but with averted eyes, "I leave the country to-morrow, never to return. Do not ask me why. You will know soon enough after I have gone. See, I have so much money," and he emptied the contents of his purse upon the table. "It is enough for the present, perhaps, but I shall some day need more, and I leave behind me accounts and stock, to say nothing of business good will, that are of value. I want you to help me realize upon them."

Vargovitch looked sternly at his friend.

"That mad head of yours," he responded, "has led you at last to difficulty from which there is no exit. I will ask no questions, Litizki, but I will not be concerned in your affair. You should not have come here."
