And at that the viscount laughed. "I haven't heard anything," he retorted. "I've seen. And I'm like you--I believe what my eyes tell me.

Your eyes told you I was butchered to death at Spion Kop, and you couldn't be convinced I wasn't until you saw me here to-night resurrected. You wouldn't take my written word, and I can't take your spoken word. The evidence to the contrary is too strong."

The colonel was again silent. He lifted his gla.s.s and drained it.

"I'm glad you called," Kneedrock continued. "Not that I needed any further conviction, but--"

"Further conviction?" Darling broke in. "I thought--"

"That you were yourself the only conviction. Oh, no. I knew before you came. I saw before you came. I had already made up my mind to go back without seeing you."

Darling gazed at him in mingled amazement and perplexity.

"I--I don't understand," he faltered. "You--you've seen Nina, perhaps?"

"I've seen Nina."

"And it was she who told you?"

"She hasn't spoken to me. I am going away without so much as a word from her or to her."

The colonel's perplexity waxed greater. "Will you kindly tell me what under Heaven you're driving at? It's all a riddle to me--a d.a.m.ned--"

"I'll not tell you another word," the other answered. "You must know all I do--and more, I dare say. Why should I add anything to the bare fact that I know where the fault lies, and that it is not in you?"

"Because you've said too much to leave it where it is," Darling insisted. "You must say it. You must say what you saw, and where and when you saw it."

But then Kneedrock laughed again in his grim, bitter fashion.

"You're not my superior officer here, remember," he came back. "I obey no commands but my own; and I refuse to submit to dictation."

The red flag of anger overspread Darling's visage.

"I infer that you have been spying," he charged.

"You may infer what you please--even that if it gives you any satisfaction. I shall not presume to dictate to you, either."

At that instant the bandaged hand protruded by chance a bit beyond its sling, and Darling's gaze rested upon it.

"I begin to see," he said more calmly.

The other noted the look and caught the inference. "Oh, this!" he exclaimed, holding it up. "Rather nasty."

"How did you get it?" asked the colonel boldly.

"Man-eater," was the answer. "Vicious beast!"

"You've been in the jungle, then?"

Kneedrock calmly began refilling his pipe. "Didn't Mayhan tell you?" he queried.

"Not a word."

"Ah! Yes, I've been in the jungle, and I stumbled on a she-tiger's lair." It was not intentional, but the manner of the speech gave it a significance aside from the phrasing.

Darling was standing by a table, and as he dropped his eyes musingly they rested on a small object that lay beside the tray of decanters and gla.s.ses. In an instant he was holding it up.

"May I have this?" he asked. It was a .45-caliber bullet, and the blood on it was still damp.

"No," refused Kneedrock flatly.

"I fancied not," rejoined the colonel. "You're keeping it as a souvenir, I suppose."

"I'm keeping it as evidence," the viscount said, lighting his pipe.

Later that night Jack Darling did an utterly unheard of thing. He knocked loudly on the door of his wife's bed-chamber and demanded admittance.

Nina, who had not yet fallen asleep, sat up in alarm, gathered herself together with an effort, and then, strangely enough, admitted her husband without protest. And if there can be a comparison in unheard of things, this was still more utterly unheard of.

She had turned up the reading-lamp, which, being shaded and its glow directed toward a limited area, did little more than make the general darkness of the room visible. Then she sat down on the bed's edge within the glow's circ.u.mference and waited.

Jack Darling didn't sit down. He stood in the shadow biting the ends of his mustache, his hands behind him, and his gaze, which was fixed on Nina, narrowed. She felt in her heart that something momentous was about to transpire; and it would be idle to say she was without suspicion of the underlying cause. For the report brought her by young Andrews had fallen far short of either satisfying or giving adequate relief to her anxieties.

Still she was not prepared for her husband's first and deliberately spoken sentence, which was:

"I have just come from Harry Kneedrock."

Nina wanted to scream then, but she couldn't. Her breath came too short.

And she needed every bit of breath she could draw, because her heart had grown suddenly big in her breast and was pounding fearfully.

She felt, too, that if she opened her mouth it must pop out. It was only by breathing rapidly and keeping her lips tight-closed that she kept it in.

"He arrived in Umballa this evening early," Jack Darling pursued. "He saw you and got an ugly shot in the hand from--this."

He held something up which caught and reflected all the diffused light that had stolen outside the illuminated circle; and she saw it was the Andrews automatic. Still she couldn't have spoken had death threatened her for her silence.

"I found it in the drawing-room. Its magazine lacks a single cartridge.

I've talked to Jowar, and everything fits. But there's something that Kneedrock won't say and that Jowar doesn't know. So I've come to you for it, and you'll tell me. You must."

He waited a moment for her to say something, but she was still mute. Her eyes were all pupils. They appeared like two black holes in a face devoid of any tint of color, for her lips were blanched and her lifted brows were hidden behind her drooping hair.

"I must know what it was that Kneedrock saw," he pressed.

Her hands were gripping the mattress on either side of her--gripping it until her finger-nails doubled and then broke.

"And I must know why he was shot at," he added.
