“Yes, I have indeed,” she answered, becoming suddenly grave, as she thought of the all pervading murk and the blackened vista of chimney stacks. Then, as they gained the broad end of the pond, and she climbed lightly over the fence on to the road that ran along the top of the sluice—“What an awfully picturesque old place Heath Hover looks from here, Uncle Seward. By the way, it’s a curious name. What does it come from?”

“Ah—ah! An enquiring mind? I suppose that goes on all fours with the love of old stones—eh? Heath I take it is after the surroundings. When you get up beyond these woods you’re on heathery slopes, which glow red in summer, so I suppose they called it after that; the other in local parlance is something coldish or damp, and this house is situated that way in all conscience. So there you are.”

“How ripping, I would like to see that same red glow.”

“Well, and you will,” he answered. “But you’ll have to wait for it, like for everything else. And summer’s none too near just now.”

They were halfway down the path from the sluice by now. Melian had halted to take in the view, her eyes wide open and fairly revelling in it. Mervyn did not fail to notice that one foot rested on the largish round stone which covered something—which constituted the tombstone of—something. And then, whether it was that the stone was slippery with the frost, her footing suddenly failed, and she would have fallen, had he not caught her in a firm grasp.

“Steady up, child,” he laughed, as he set her on her feet again. “Why you haven’t got your ice legs even yet, although we’ve walked down that long frozen pond.”

She laughed too. But the coincidence struck him. Why on earth should that have been the one stone of all those around, on which she should have chanced to trip? It was significant. Further, as they resumed their way, he noticed that the stone had been displaced, though ever so little. Even that circumstance sent an uneasy chill through him. It had been firm enough before. Could the frost have loosened it? Or—could any other agency? And then came the sound of approaching footsteps on the road above.

“Good-day, sir,” and the passing man saluted, respectfully enough. “Sharp, middlin’ weather, this, sir?”

“It is,” he answered, with a genial nod, and the man passed on.

“You remember what I told you about being under police surveillance,” he said as they entered the house—old Judy could be dimly heard grumbling at her ancient proprietor through the back of the kitchen door.
