"But we haven't a trail to follow; I believe we'll find that leopard back in his cage."

"Good heavens, man, he couldn't get through the solid wall!"

"But he did."

Finnerty blinked his eyes in unison with his rapid thoughts. A suspicion lingered in his mind that the animal had really slipped from the cave without Swinton seeing him—perhaps through his attention having been taken up by Mahadua. Indeed it was the only reasonable explanation of his astounding disappearance. With boyish diffidence he asked: "Did you and Mahadua do anything; that is, did he take up your attention with—well, he's a garrulous old cuss, especially on spirits."

Swinton in candour related what had occurred, and when he told of the rupee-gun ceremony the major, with a start, exclaimed: "Ah!"

"I know what you mean by that, major," Swinton said, with a little laugh, "but I never took my eyes off that hole in the wall."

But Finnerty shook his head. "Do you know what they call the leopard in every mess in India?—'The Artful Dodger.'" Then he added hastily: "We'll settle your theory first, captain. On our way back to have some breakfast we'll look in at the zoo, and if there's a black leopard there with a wound it will be the one we're after; if there is one without a wound it will mean that we shot a jungle beast last night; if the cage is empty the brute either slipped your vigilance or is, as Mahadua says, a spirit."

The word leopard being familiar to the servant, he knew what the sahibs were discussing, and contributed: "Our eyes were always on the door, sahib, and if a spirit took the leopard through the walls he would lead him to Kohima, for it is said that all his kills were made through the aid of one he acquired there."

"Come on!" Finnerty said. "We're in a fit condition of mystification to almost accept the little man's thesis."

A strange attendant was at the teakwood gate, but when the major explained that they simply wanted a look at the animals, being sahibs, he swung the gate for their entrance, closing it from the inside to stand near them. The heavily barred cage was empty, and there was no movement in the den behind to which a small door gave entrance.
