Anthony frowned. “Seems rather rotten to me.”

“To interview her? Not necessarily, at all. She might have something to say that she’d very much like published. She knows that the uncompromising fact about that ten thousand pounds is going to be talked about pretty hard if there’s any question of Mrs. Vane’s death not being an accident; naturally she’d like an opportunity of putting an indirect answer of her own forward.”

“I never thought of that,” Anthony confessed, his frown disappearing.

“Nor did I, till this minute,” Roger said candidly. “Still, it’s true enough. And there’s a little job for you, Anthony. I shan’t want you with me while I’m talking to Moresby; it’s going to be difficult enough to get anything out of him in any case, but your presence would probably dry him up altogether. So you might stroll along the cliffs, locate the Vanes’ house, and see if you can discover unobtrusively any information as to the girl’s movements or where I might be likely to catch her—outside the house, of course, if possible. What about that?”

“Yes, I could do that for you. And meet you later on?”

“Yes; just stroll back along the top of the cliffs again and I shall be sure to run into you. Well, there’s the sea not three hundred yards ahead, and nothing but nice, open downs along the top of the cliffs up there. We turn off to the right, I suppose, and you go straight along while I make for the edge just over there. I expect I shall be through in something under an hour. So long!”

As Anthony made his way leisurely over the springy turf in the direction in which he judged his objective to lie, he pondered with no little interest over the object of their journey down to this charming part of the world and its possible outcome. There was in his make-up none of that eager curiosity regarding his fellow-creatures, their minds and the passions which sway them that had led Roger, after the way had once been opened to him, to explore the vast field of criminology with all its intense and absorbing interest for the student of the human animal. Indeed the notion of nosing out hidden facts and secret horrors (“like a bally policeman,” as he had contemptuously phrased it to Roger over their lunch on the train) had at first actually repelled him; it was not until Roger had been at considerable pains to point out the moral duty which every living person owes to the dead that his eyes were opened to any wider conception of the idea. And even then, though admitting that there must be detectives just as much as there must be hangmen, he was quite firm in his gratitude to Providence that he at any rate was not one of them; nor could Roger, expatiating on the glories of a clever piece of deductive reasoning, the exquisite satisfaction of logical proof, the ardour of the chase with a human quarry (but none the less a quarry that in ninety-nine cases out of a hundred deserved not a jot of mercy) at the end of it, move him an inch from this position.

It was this state of mind which had caused him to receive with ominous disapproval Roger’s pointed information about the girl cousin and her ten thousand pounds. A girl, to Anthony’s mind, should not be mentioned in the same breath as the word murder. Girls were things apart. Murder concerned men; not girls. Girls might be and very often were murdered, but not by other girls. If it were distasteful to hunt down a man suspected of murder, how impossible would it not be to harry a wretched girl in the same circumstances?

As his thoughts progressed with his steps, an idea began to form in Anthony’s mind. He would not only seek out the whereabouts of Miss Cross, as Roger had asked him; he would contrive to speak to her for a minute or two and, if possible, drop a veiled warning as to the things that might be expected to happen—that were, in fact, even now happening—together with an equally veiled hint that at any rate he, Anthony Walton, was prepared to extend to her any help within his power, should she wish to accept it. After all, that was the least a chap could do. It was the only decent thing. Ten to one she wouldn’t need anything of the sort, but the offer—yes, of course it was the only decent thing to do. Girls were weak, helpless things. Let them know they’ve got a man behind them (even a perfect stranger if the case is serious enough to warrant it) and it makes all the difference in the world to ’em. Naturally!

In the glow of this resolution Anthony had unconsciously directed his steps toward the sea, so that he was now striding along the very edge of the cliffs. Coming to his senses with a jerk, he pulled up short and looked inland. Not five hundred yards to his right there stood, in a large fenced area which evidently stretched to the road half-a-mile away, a big red house. As the landlord of the inn had said, there was no mistaking it. Anthony gazed at it for a few moments without moving; now that he was face to face with it, the task of penetrating its purlieus and demanding speech with an unknown lady in order to warn her against dangers which quite probably did not exist at all, suddenly took on a somewhat formidable aspect.
