Spencer at once suspected the man’s motives, not without fair cause. They were, he thought, as plain to him as they were hidden from the girl. Bower counterfeited the genuine surprise on Helen’s face with admirable skill; but, to the startled onlooker, peering beneath the actor’s mask, his stagy artifice was laid bare.

And Spencer was quite helpless, a condition that irritated him almost beyond control. He had absolutely no grounds for interference. He could only glower angrily and in silence at a meeting he could not prevent. Conjecture might run riot as to the causes which had given this sinister bend to an idyl, but perforce he must remain dumb.

From one point of view, it was lucky that Helen’s self appointed “godfather” was in a position not to misjudge her; from another, it would have been better for Spencer’s peace of mind were he left in ignorance of the trap that was apparently being laid for her. Perhaps Fate had planned this thing—having lately smiled on the American, she may have determined to plague him somewhat. At any rate, in that instant the whole trend of his purpose took a new turn. From a general belief that he would never again set eyes on one in whose fortunes he felt a transient interest, his intent swerved to a fixed resolve to protect her from Bower. It would have puzzled him to assign a motive for his dislike of the man. But the feeling was there, strong and active. It even gave him a certain satisfaction to remember that he was hostile to Bower before he had seen him.

Indeed, he nearly yielded to the momentary impulse that bade him hasten to the booking office and secure a ticket for St. Moritz forthwith. He dismissed the notion as quixotic and unnecessary. Bower’s attitude in not pressing his company on Miss Wynton at this initial stage of the journey revealed a subtlety that demanded equal restraint on Spencer’s part. Helen herself was so far from suspecting the truth that Bower would be compelled to keep up the pretense of a casual rencontre. Nevertheless, Spencer’s chivalric nature was stirred to the depths. The conversation overheard in the Embankment Hotel had given him a knowledge of the characteristics of two women that would have amazed both of them were they told of it. He was able to measure too the exact extent of Bower’s acquaintance with Helen, while he was confident that the relationship between Bower and Millicent Jaques had gone a great deal further than might be inferred from the actress’s curt statement that he was one whom she “wished to avoid.” These two extremes could be reconciled only by a most unfavorable estimate of Bower, and that the American conceded without argument.

Of course, there remained the possibility that Bower was really a traveler that day by idle chance; but Spencer blew aside this alternative with the first whiff of smoke from the cigar he lit mechanically as soon as the train left the station.

“No,” he said, in grim self communing, “the skunk found out somehow that she was going abroad, and planned to accompany her. I could see it in the smirk on his face as soon as he discovered her whereabouts on the platform. If he means to summer at Maloja, I guess my thousand dollars was expended to no good purpose, and the quicker I put up another thousand to pull things straight the happier I shall be. And let me tell you, mother, that if I get Helen through this business well and happy, I shall quit fooling round as godfather, or stage uncle, or any other sort of soft-hearted idiot. Meanwhile, Bower has jumped my claim.”

His glance happened to fall on an official with the legend “Ticket Inspector” on the collar of his coat. He remembered that this man, or some other closely resembling him, had visited the carriage in which Bower traveled.

“Say,” he cried, hailing him on the spur of the moment, “when does the next train leave for St. Moritz?”

“At two-twenty from Charing Cross, sir. But the Engadine Express is the best one. Did you miss it?”

“No. I just blew in here to see a friend off, and the trip kind of appealed to me. Did you notice a reserved compartment for a Mr. Mark Bower?”
