"He is dead," said Paul; "but this is no time for words. The assassin is among yon crowd, and his name is Ivan Russakoff."

The name of the spy acted like magic upon Zabern. He shouted some order, and in a moment more ten uhlans trotting forward with couched lances scattered the crowd; the object of these troopers was to secure the Troitzka Gate, and so prevent the assassin from making his escape by this exit. Like precautions were promptly taken with the rest of the city gates. The remainder of his forces Zabern skilfully disposed around the suburb of Russograd, forming them into a cordon through which no one could break without detection.

Meanwhile, in answer to his summons, fresh detachments of troops arrived together with a numerous corps of police; and to both he briefly explained the object of the muster.

Zabern was well aware that, owing to the hostility with which Polish authority was viewed in this quarter, he would have considerable difficulty in inducing the Muscovites to surrender the spy, whose act in slaying a government official would be certain to enlist their sympathies. Every dweller in Russograd would take a pride in concealing the felon. Hence the marshal was necessitated to make his arrangements with almost the same care as if conducting a siege. For a few hours Russograd was to become subject to martial law,—no new experience for this riotous faubourg.

"Remember, Russakoff must be taken alive; his dead body is of no use to me," said Zabern. "But as to the rest, don't hesitate to shoot if there should be any resistance. Nikita," he added, addressing his orderly, "dismount, and assist Katina in conveying the body to the palace. Captain Woodville, here is a horse at your service. You will accompany us?"

Zabern's elaborate precautions failed to secure the person of the spy.

Though all the streets of Russograd were traversed by the military, and every individual subjected to scrutiny; though private dwelling and public building were explored by keen-eyed police; and though the marshal and his staff formed a sort of inquisitorial tribunal and interrogated and cross-examined during the whole night, yet no one answering to the description of Russakoff could be found.

Still the marshal continued the search, encouraged by the statement alike of the sentinels at the city gates as of the members composing the military cordon, that the spy had not passed outwards.

"So, Nariskin," he said at seven next morning, and addressing a patriarchal, long-bearded individual who carried himself with some show of authority, "so, Nariskin, another government official murdered in your ghetto! A pretty guard your night-watch keep!"

Nariskin, chief of the ward council that directed the affairs of Russograd, became voluble in attesting his grief,—his indignation,—his horror, that anything so—so—
