After that he lighted a very large cigarette, half as big as a cigar, and he lay back in his low comfortable chair, and began to think of the outcome of all this plotting and planning. As is very apt to be the case when a great danger has been escaped, he was in a mood of extreme hopefulness and confidence. Vaguely he felt as if the recent happenings had set him ahead a pace towards his goal, though, of course, they had done nothing of the kind. The danger that would exist so long as Ste. Marie, who knew everything, was alive, seemed in some miraculous fashion to have dwindled to insignificance; in this rebound from fear and despair, difficulties were swept away and the path was clear. The man's mind leapt to his goal, and a little shiver of prospective joy ran over him. Once that goal gained he could defy the world. Let eyes look askance, let tongues wag, he would be safe then—safe for all the rest of his life, and rich, rich, rich!
For he was playing against a feeble old man's life. Day by day he watched the low flame sink lower, as the flame of an exhausted lamp sinks and flickers. It was slow, for the old man had still a little strength left, but the will to live—which was the oil in the lamp—was almost gone and the waiting could not be long now. One day, quite suddenly, the flame would sink down to almost nothing, as at last it does in the spent lamp. It would flicker up and down rapidly for a few moments, and all at once there would be no flame there. Old David would be dead, and a servant would be sent across the river in haste to the Rue du Faubourg St. Honoré. Stewart lay back in his chair and tried to imagine that it was true, that it had already happened, as happen it must before long, and once more the little shiver which was like a shiver of voluptuous delight ran up and down his limbs, and his breath began to come fast and hard.
But Richard Hartley drove at once back to the Rue d'Assas. He was not very much disappointed in having learnt nothing from Stewart, though he was thoroughly angry at that gentleman's hint about Ste. Marie and the unknown lady. He had gone to the Rue du Faubourg because, as he had said, he wished to leave no stone unturned, and, after all, he had thought it quite possible that Stewart could give him some information which would be of value. Hartley firmly believed the elder man to be a rascal, but, of course, he knew nothing definite save the two facts which he had accidentally learnt from Helen Benham, and it had occurred to him that Captain Stewart might have sent Ste. Marie off upon another wild-goose chase such as the expedition to Dinard had been. He would have been sure that the elder man had had something do to with Ste. Marie's disappearance if the latter had not been seen since Stewart's party, but instead of that Ste. Marie had come home, slept, gone out the next morning, returned again, received a visitor, and gone out to lunch. It was all very puzzling and mysterious.
His mind went back to the brief interview with Stewart and dwelt upon it. Little things which had at the time made no impression upon him began to recur and to take on significance. He remembered the elder man's odd and strained manner at the beginning, his sudden and causeless change to ease and a something that was almost like a triumphant excitement, and then his absurd story about Ste. Marie's flirtation with a lady. Hartley thought of these things, he thought also of the fact that Ste. Marie had disappeared immediately after hearing grave accusations against Stewart. Could he have lost his head, rushed across the city at once to confront the middle-aged villain, and then—disappeared from human ken? It would have been very like him to do something rashly impulsive upon reading that note.
Hartley broke into a sudden laugh of sheer amusement when he realised to what a wild and improbable flight his fancy was soaring. He could not quite rid himself of a feeling that Stewart was, in some mysterious fashion, responsible for his friend's vanishing. But he was unlike Ste. Marie; he did not trust his feelings, either good or bad, unless they were backed by excellent evidence, and he had to admit that there was not a single scrap of evidence, in this instance, against Miss Benham's uncle.
The girl's name recalled him to another duty. He must tell her about Ste. Marie. He was by this time halfway up the Boulevard St. Germain, but he gave a new order and the fiacre turned back to the Rue de l'Université. The footman at the door said that mademoiselle was not in the drawing-room, as it was only four o'clock, but that he thought she was in the house. So Hartley sent up his name and went in to wait.
Miss Benham came down looking a little pale and anxious.
"I've been with grandfather," she explained. "He had some sort of sinking spell last night, and we were very much frightened. He's much better, but—well he couldn't have many such spells and live. I'm afraid he grows a good deal weaker, day by day, now. He sees hardly any one outside the family, except Baron de Vries." She sat down with a little sigh of fatigue and smiled up at her visitor.
"I'm glad you've come," said she. "You'll cheer me up and I rather need it. What are you looking so solemn about, though? You won't cheer me up if you look like that."
"Well, you see," said Hartley, "I came at this impossible hour to bring you some bad news. I'm sorry.
