“I shouldn’t wonder if we were, Mr Mervyn,” rejoined the inspector, again rather drily.

“Couldn’t we trace his footmarks back?” suggested the doctor. “It would show the direction he had come from, and then we could make enquiries. Eh, Nashby?”

“The very thing I was going to do,” answered the latter.

But the plan, though good, was difficult of execution. The footmarks were almost obliterated by the more recent snowfall, in places quite so. And they led from nowhere direct. They zigzagged and twisted, as though their perpetrator were wandering at random and round and round, then lost themselves altogether in a sort of small ravine. But the very incoherency of their course suggested a reason for the stranger plunging into the peril he had done. Clearly he had got lost in the thick woods and had welcomed this long, broad stretch of open, and apparently strong ice, as a way out.

“Now I would suggest an adjournment for lunch,” said Mervyn. “We can take up the trail afterwards where we left it.”

“That’s not half a bad idea,” assented the doctor heartily. “Thanks very much, Mr Mervyn. I’d been about a bit before I started for here, and after a drive through this invigorating air, it seems a long while ago since breakfast time.”

Inspector Nashby raised no objection. A stalwart police officer, even though on an interesting case, and prospectively a case for advancement, is not proof against the pangs of deferred appetite on a crisp, keen, frosty day. But even while discussing good cheer in an impromptu way in Mervyn’s kitchen—for they left the living-room in silent possession of the dead—Nashby kept his eyes about him and his perceptions at full cock. For Nashby had his theories already forming. The doctor as yet had formed none.

While thus engaged, they missed the fact that the sun-bright day had overclouded. They were awakened to it, however, by the discovery that it had begun to snow again. More than begun indeed, for the snow was coming down, not merely in flakes, but almost in slabs. A little more of it and they would hardly be able to get back to Clancehurst. The Inspector jumped to his feet.

“Heavens!” he ejaculated, going to the window. “Why, this’ll cover up all and any footprints there may be to find beyond where we left off.”

“Shouldn’t wonder if it did. Well, it can’t be helped,” said Mervyn coolly. He had by now quite got behind the policeman’s suspicions, and was taking rather a half-hearted delight in teasing that worthy. “Have another whisky and soda, inspector?”
