"There," he thought, as he contemplated his finished work, "if our spy is not more observing and suspicious than I think he is, I shall be able to take a look at him occasionally."

Having carefully cleaned up the slight litter he had made, he locked the door of his room and went to make his report to Clara.

He told her frankly that he believed Litizki had been mistaken about the little front room. "But," he added, "I have taken the back room for a week, and I shall be surprised if I do not make some discovery before my time is up."

Intent upon being on the ground, where he could watch every movement of Poubalov, he hurried back to Bulfinch Place, and sat himself down to pass time with books until the spy should come in.

All day long Clara heeded her uncle's injunction to rest, but that was because there was nothing she could do. Moreover, she expected Poubalov, and she was more than anxious to be at home to receive him. He came about five o'clock. The young ladies were refreshing themselves with tea, and Louise, who never ceased to be amazed at her cousin's proceedings, almost gasped when she saw Clara greet him cordially and hasten to get a cup for him.

One would not have expected Poubalov to show fatigue, if he ever felt it, but if he were not weary on this occasion, something had occurred to disturb him. His eyes were heavy, his accent harder to understand than usual, and it was not until several minutes had passed, and he had drank freely of tea, that he spoke with anything like his customary masterful confidence. Clara led the conversation at the start. After the first greetings she referred to the episode in the car, saying:

"I should have thought you would suffer as I did from the shock of that terrible assault. It was dreadful to look at, and how much more dreadful to be the intended victim."

"You are mistaken, Miss Hilman," responded the spy; "the very shock of the blow convinced me that I was unharmed. There was therefore no more occasion for alarm on my part than as if a book had fallen from the rack upon my head."

"But, really, I supposed the worst had happened," insisted Clara, "for you not only fell but you gasped——"

"Naturally. To put it roughly, the fellow knocked the breath out of me."
