[CHAPTER XXII.]

POUBALOV'S REVOLUTION.

Paul's heart seemed to stand still as he reflected on Poubalov's act. The original purpose of the spy in calling upon Strobel and instigating his abduction, was as much a mystery as ever, but it was one that could be explained on the ground of Poubalov's confessed relations with the government with which Strobel had been in conflict. There was nothing personal in that; but here was an element of personal relationship that might lead to worse than complications.

Poubalov in love—no! not that sacred word; infatuated, rather, with Clara Hilman.

What hope could there now be that the spy, having some day accomplished the purpose for which he had crossed the ocean to find Strobel, would set him free? In the very hopelessness of his passion would he not first murder Strobel, and then Clara herself? Paul felt sick with horror as the possibility of these tragedies occurred to his mind. They were more than possible. With Poubalov's character in view, they seemed like certainties. What could be done to avert them? What would Clara say? How revolting, more than terrifying, would be the revelation that this subtle, conscienceless foe had dared to love her!

At first blush Paul felt that he could not tell Clara what he had seen. If there were only something that he himself could do to solve the mystery of Ivan's disappearance, for only Strobel's presence in perfect health could serve to check the spy's villainous course. He held absolute command of the situation as long as he succeeded in keeping Strobel in hiding. As the sense of his helplessness grew upon him, like an insidious vine whose twining tendrils choke the growth of a sapling, Paul wondered that poor Litizki's devotion had not the sooner driven him to madness.

He saw that, with all its evils, the situation must be made clear to Clara. He would continue his observations during the next forenoon, and then report to her.

Poubalov had said that he would call in the evening; Clara, therefore, in the early afternoon went to see Mrs. White. She went with no purpose of accomplishing anything in the mystery, but rather as an act of kindness to report how she had found Lizzie; but as she was about to turn into Ashburton Place, she saw Paul at the foot of the hill and she waited for him to come up. He had just started for Roxbury.

"I have something to tell," he said in answer to her anxious look of inquiry, "but I fear it is nothing that will be helpful, and it will certainly be disagreeable."

"I was going to call on Mrs. White," responded Clara; "suppose you go with me; but you can tell me what you have discovered before we go in."
