He went to the corner of Bowdoin Street, and back on the other side to a point directly opposite Poubalov's windows.

As he walked, one deep-toned stroke rang out from a neighboring church tower.

If that was the hour Poubalov had set for putting a bullet into his heart, he had let it pass without taking action.

Paul kept his eyes upon the curtained windows behind which the chandelier light still glowed, and longed to be back at his peephole, watching the spy. Yet there was nothing that he could do if he were there. He had seen the one great incident in Poubalov's career come to its climax upon the awful verge of tragedy; and he felt that as the spy's life trembled in the balance, the weight had been thrown into the scale for prolonging it by his impulsive jump from the chair on which he had been viewing the scene.

Not that Poubalov was hesitating; his was the nerve to pull the trigger with the precision and steadiness of a marksman when the appointed time came; but the shock of irrelevant circumstances had been just what was needed to release the morbid pressure of gloomy contemplation from the brain, and restore it to its normal activity.

Thus Paul reflected, with his eyes upon the lighted windows. A party of roysterers swung into the place, singing discordantly. One of them fell at the corner of Bowdoin Street, and his companions helped him up with drunken jeers and laughter. Paul had turned his head to watch them, and when he looked again at the lodging-house across the way, all the windows were dark. Poubalov had gone to bed.

As faithful as the unfortunate Litizki to his task, Paul sat up all that night. When drowsiness overcame him, he bathed his face and head with water, or walked gently about the room. He smoked all the cigarettes in his possession, for the sake of having something to do, and when his stock was exhausted, he went to a neighboring "all-night" restaurant and bought a handful of cigars. He listened through the hours for any suggestive sound from the front room, but, beyond an occasional deep breath, he heard nothing.

Poubalov slept well.

It was not until the day, reckoning by the light, was well advanced, that the spy rose and dressed. While he was still busy with his toilet, a messenger called and left a note for Paul with word to the scrub-woman who was already at work, that it was to be delivered at once. It was from Clara.
