Emerson sneezed.

"I beg that you will leave off tickling me," he said irritably. "The region around the chin and jaw is particularly sensitive. For G.o.d's sake, Peabody, stop sniveling; it is only a cut from a bit of flying rock."

"Oh," I said. "But the shot was aimed at you! In heaven's name, what are you doing now? Don't go out there- "

He was crawling toward the entrance.

"The shot was meant as a warning," he said over his shoulder. "We are safe enough- for the moment- unless we try to leave the tomb. Hand me that shut of Walter's, if you please- it is lying across his bed- and my walking stick. Thank you. Now let us see- "

A second shot rewarded his demonstration when he draped the shirt over the stick and extended it out the doorway. Emerson withdrew it. "He is there, among the rocks," he said calmly.

"He? Who?"

"You sound like one of the villagers' donkeys," said Emerson. "Who else could it be? You must have deduced his ident.i.ty by now. I have known it for some time; but his motive still eludes me. What the devil ails the fellow, to seek to win a wife by such means? I would not have thought him capable of the insane pa.s.sion that prompts such acts."

Once- even a few hours earlier- his calm, drawling voice would have driven me wild. Now I was seized by the same icy calm. We had already delayed too long; even if we could escape from this ambush uninjured, Evelyn and her abductor would be out of sight. It was up to Walter now. At least he had only one enemy to face. The other was below, with rifle in his hands.

"There is motive," I said. "I am only now beginning to see.... No, no, it is impossible. From the first I too suspected Lucas. But he was not here. He did not arrive until long after we did, long after the Mummy made its first appearance. He did not know we would stop here-"

"I think it is high time we compared notes," said Emerson, rec.u.mbent before the entrance. "You might give Michael a little water, Peabody; I fear that is all we can do for the poor fellow now, since we dare not strike a light, and your medical supplies are in your sleeping chamber. Then come here and join me."

I did what I could for Michael. It was little enough. He was still breathing, but that was about all I could say. I then crawled to the entrance and lay down flat, next to Emerson, who was peering out across the moonlit plain, his chin propped on his folded arms. "You and I have been at cross purposes since we met,

Peabody," he said. "It is a pity; for we might have prevented this unfortunate business if we had taken the trouble to be civil to one another. You see, I have known for some days that his lordship has been lying. Reis Ha.s.san talked to the reis of the Cleopatra Cleopatra, and pa.s.sed some of the gossip on to me. His lordship's payments to his crew have been princely. By means of exorbitant bribes, he got underway the very day after you left. He was moored downriver, at Minieh, the day you landed here.

"But that is not the important thing. His lordship has a confederate- not a hired native, but a man as dedicated to evil as he is. That confederate is the man who is playing the role of the Mummy. This man's whereabouts, prior to his public appearance here, are unknown. I believe he came here some time ago and set the scene for the drama- bribing Mohammed, introducing the mummy Walter found into an empty tomb. His costume, his role were planned well in advance- probably in Cairo, where, I imagine, young Lord Ellesmere arrived earlier than he led you to believe. Do you have an idea who this confederate might be?"

"No. Lucas must have bribed him well. Of course it could be a friend of Lucas's- one of his companions in vice. I do not know them. But, Emerson, there is one great flaw in your argument. How could they know where to set the scene? We did not plan to stop here - "

"Then Reis Ha.s.san is a liar. He informs me that you laid out your itinerary while still in Cairo, and that he tried several times to dissuade you from it."

"Oh, that. I did mention the possibility of visiting Amarna- along with a number of other sites. But how could Lucas know?"

"From Michael, I imagine. Did he have an opportunity to speak with him before you left Cairo?"

"He did indeed," I said grimly. "And to think that we introduced them, so that Michael might a.s.sist Lucas in the selection of a dragoman ----- Good G.o.d, what a fool I was!"

"You had no reason to suspect any danger. Nor did Michael. His lordship was your friend, Evelyn's relation. It was not until developments here became serious that Michael began to wonder about his harmless indiscretion. He is an intelligent man, and devoted to you body and soul; on the day of his disappearance he asked to speak to you alone - "

"And Lucas heard him! He struck him down and spirited him away."

"Not Lucas, but one of his men. He kept the poor fellow prisoner in one of the caves that are so common in these cliffs, and when we obstinately refused to succ.u.mb to the laudanum he had placed in our wine, he carried Michael here to distract us while his confederate reached Evelyn.

"I must admit that the fellow has imagination; he acts brilliantly and unhesitatingly in emergencies, and makes good use of any fortuitous circ.u.mstances that can be turned to account. My illness was one such lucky accident- lucky for him- but I feel sure he and his confederate had planned some means of detaining you here- damage to the dahabeeyah, or to one of us. At that point in time, his lordship had not determined to commit murder. He hoped to attain his ends by less drastic means, although it seems clear he prepared for the worst, in case it should become necessary. And I was misled. Not until you were attacked this afternoon did I fully realize that Evelyn was the real object of the attentions we have been receiving, and even then I was fool enough to suppose that once she had accepted Walter, his lordship would give up his idiotic and dangerous games."

Emerson extended his stick once again out the entrance. Another shot rang out, followed by the splintering of rock.

"Still there," he said. "I wonder how long he means to keep us here. We are safe so long as we do not confront him. He will have some specious excuse to explain why he failed to rescue Evelyn; I think the fellow is actually vain enough to suppose he can get away with it. Shall we save our skins, Peabody, and sit still?"

"While Evelyn is in the clutches of that monster?" I demanded. "Don't bait me, Emerson; you have no more intention of accepting this than I do. Do you think Walter- "

"I am extremely concerned about Walter," said Emerson; I knew him well enough now to hear the controlled agony under his calm tones. "But at the moment we can do nothing to help him or Evelyn until we understand what is behind this affair. There is some more desperate motive behind his lordship's acts than frustrated love. Think, Peabody; if you have ever used your brain, now is the time."

"I have a faint inkling of the truth," I said, in a stifled voice. "I hate to contemplate it; for if I am right ----- Emerson, you and I have behaved like fools. If I had known what you knew about Lucas's movements; and if you had known what I am about to tell you - "

"Speak, then. That is the trouble with women, even the best of them," Emerson added. "They will indulge in vain cries of 'if only' and 'had I but known.'"

"The criticism is justified," I said; my pride was thoroughly leveled by the magnitude of the disaster. "Listen, men, while I narrate Evelyn's story."

He listened. Only his eyes moved, so intent was he on what I had to say.

"Yes," he said, when I finished. "The clue is there, somewhere. A vast amount of money may be an inducement to violence. But how? I cannot see it, even now. Is it possible that his lordship lied to you about the old man's death? If he still lives, and contemplates restoring Evelyn as his heiress - "

"No, he is dead; one of my acquaintances in Cairo knew of it."

Emerson struck his fist against the floor.

"The conclusion is inescapable, Peabody; in some way we do not comprehend, Evelyn must have control of the fortune his lordship so ardently desires. He has done everything a man could do to induce her to become bis wife. I believed his sole motive was pa.s.sionate love of his cousin. But in this day and age an English girl cannot be forced into marriage, and a forced marriage is the only kind that could come out of this night's work. Nothing the wretch could do now would induce Evelyn to marry him of her own free will. No; it is the lady's money that is being sought, not the lady's person. If we only knew how - "

"I believe I do know," I interrupted. "I told you that before the late Lord Ellesmere died he gathered all Evelyn's belongings and sent them to her. Lucas told me- good heavens, he actually boasted of it- that he was in full control at Ellesmere Castle while the old gentleman lay ill. If Ellesmere had softened toward Evelyn and wished to restore her to favor, Lucas would make certain he did not reach his lawyers in order to make a new will. But he might write a new will- a holograph will, I believe it is called. Knowing Lucas as he did, the poor old man saw only one way to ensure that such a doc.u.ment would survive. He could send it to Evelyn- packed in with her other Possessions. He hoped to escape arousing Lucas's suspicions that way."

"By Gad, Peabody, I think you've got it!" Emerson exclaimed.

"I think so too. Lucas has tried every possible means of getting to those boxes of Evelyn's, or of having them destroyed unopened. He must have missed them in Rome; and when they arrived in Egypt they went into the safekeeping of Baring, who is the most powerful man in the government. He was a friend of Father's, and he knows of Lucas's unsavory reputation; from such a man Lucas had no chance of extracting the precious boxes. Alas; for if he had- "

"Evelyn would not now be in danger," Emerson's quick wits supplied the conclusion. "He may not be certain that such a will exists, but he must have reason to suspect that it does. If he could destroy it he would be safe. Failing that, he pursued Evelyn. As her husband he would have control of her fortune in any case, and he would have a good excuse to take charge of her baggage. But the marriage plan failed as well; thanks to our strenuous efforts, his lordship has now only one means left of gaining his ends . . . . Peabody, you must not blame yourself. How could you possibly have suspected this?"

"I don't blame myself," I said,wiping away the tears that were stealing down my face. "As you say, I could not have suspected. It is the most farfetched scheme I have ever encountered; only a frivolous, amoral man, who had been reading too many wild romances, would think of such a thing. And vain regret is useless. I will not indulge in it. I will get out of here and go after Evelyn, and I will kill his lordship if he has harmed her."

I rose to my knees. Emerson put his hand in the center of my back and pushed me down again.

"I am in complete agreement with your program. But let us try to think of some safer way to do it."

"Can we expect no help from anyone? What of Abdullah? And the crewmen on the boat- surely they heard the shots."

"I have grave suspicions of Abdullah," Emerson said grimly. "You forget, Peabody, that these people are desperately poor."

"And Reis Ha.s.san too? I thought he looked strange the other day when you were questioning him."

"Ha.s.san is one of the few honest men I know. Unfortunately he is also superst.i.tious. He was ashamed to admit to me that he had been terrorized by Mohammed's tales of ghosts and curses. No; he will come, I believe, if he can overcome his fears and persuade his crew. But we cannot count on that. Then there is the crew of his lordship's dahabeeyah to be considered. What if they have been paid to prevent a rescue attempt? No, Peabody, if we are to get out of here in time, it must be by ourselves. And I think we had better set about it."

"But how... ?"

"There are pebbles and rocks on the threshold. When I give the signal, begin rolling them down. Meanwhile, I will creep along the path in the other direction and try to get behind him."

"It is a foolhardy scheme," I said. "He will surely see or hear you."

"From below he has a poor chance of hitting me if I keep low. You must cover any sounds I make by the exuberance of your performance and, if possible, induce him to empty the magazine of his repeater. Come, come, Peabody; if you have any more practical suggestion, I will be happy to hear it. I have never had the inclination to be a hero. But we must do something, and soon."
