"And he'd come through here!" she exclaimed. "How dangerous!—with those things in his pocket!"

"Oh, but he'd think nothing of it!" answered Neale. "He was used to walking at night—he knew every yard of this neighbourhood. Besides, he'd know very well that nobody would know what he had on him. What I'd like to know is—supposing my theory's right, and that he was taking these jewels to Ellersdeane, how did anybody get to know that he had them? For the Chestermarkes didn't know they'd been given to him, and I didn't—nobody at the bank knew."

A sudden turn in the path brought them to the edge of the wood, and they emerged on a broad plateau of rough grass, from beneath which a wide expanse of landscape stretched away, bathed just then in floods of moonlight. Neale paused and waved his stick towards the shadowy distances and over the low levels which lay between.

"Ellersdeane Hollow!" he said.

Betty paused too, looking silently around. She saw an undulating, broken stretch of country, half-heath, half-covert, covering a square mile or so of land, houseless, solitary. In its midst rose a curiously shaped eminence or promontory, at the highest point of which some ruin or other lifted gaunt, shapeless walls against the moonlit sky. Far down beneath it, in a depression amongst the heath-clad undulations, a fire glowed red in the gloom. And on the further side of this solitude, amidst groves and plantations, the moonlight shone on the roofs and gables of half-hidden houses. Over everything hung a deep silence.

"A wild and lonely scene!" she said.

Neale raised his stick again and began to point.

"All this in front of us is called Ellersdeane Hollow," he remarked. "It's not just one depression, you see—it's a tract of unenclosed land. It's dangerous to cross, except by the paths—it's honeycombed all over with disused lead-mines—some of the old shafts are a tremendous depth. All the same, you see, there's some tinker chap, or some gipsies, camped out down there and got a fire. That old ruin, up on the crag there, is called Ellersdeane Tower—one of Lord Ellersdeane's ancestors built it for an observatory—this path'll lead us right beneath it."

"Is this the path he would have taken if he'd gone to Ellersdeane on Saturday night?" asked Betty.

"Precisely—straight ahead, past the Tower," answered Neale. "And there is Ellersdeane itself, right away in the distance, amongst its trees. There!—where the moonlight catches it. Now let your eye follow that far line of wood, over the tops of the trees about Ellersdeane village—do you see where the moonlight shines on another high roof? That's Gabriel Chestermarke's place—the Warren."
