The lights on the Egyptian sh.o.r.e were faintly visible when the last group of stragglers on deck broke up. I had long since prevailed upon Karamaneh to retire, and now, utterly sick at heart, I sought my own stateroom, mechanically undressed, and turned in.

It may, or may not be singular that I had neglected all precautions since the night of the tragedy; I was not even conscious of a desire to visit retribution upon our hidden enemy; in some strange fashion I took it for granted that there would be no further attempts upon Karamaneh, Aziz, or myself. I had not troubled to confirm Smith's surmise respecting the closing of the portholes; but I know now for a fact that, whereas they had been closed from the time of our leaving the Straits of Messina, to-night, in sight of the Egyptian coast, the regulation was relaxed again. I cannot say if this is usual, but that it occurred on this ship is a fact to which I can testify--a fact to which my attention was to be drawn dramatically.

The night was steamingly hot, and because I welcomed the circ.u.mstance that my own port was widely opened, I reflected that those on the lower decks might be open also. A faint sense of danger stirred within me; indeed, I sat upright and was about to spring out of my berth when that occurred which induced me to change my mind.

All pa.s.sengers had long since retired, and a midnight silence descended upon the ship, for we were not yet close enough to port for any unusual activities to have commenced.

Clearly outlined in the open porthole there suddenly arose that same grotesque silhouette which I had seen once before.

Prompted by I know not what, I lay still and simulated heavy breathing; for it was evident to me that I must be partly visible to the watcher, so bright was the night. For ten--twenty--thirty seconds he studied me in absolute silence, that gaunt thing so like a mummy; and, with my eyes partly closed, I watched him, breathing heavily all the time. Then, making no more noise than a cat, he moved away across the deck, and I could judge of his height by the fact that his small, swathed head remained visible almost to the time that he pa.s.sed to the end of the white boat which swung opposite my stateroom.

In a moment I slipped quietly to the floor, crossed, and peered out of the porthole; so that at last I had a clear view of the sinister mummy-man. He was crouching under the bow of the boat, and attaching to the white rails, below, a contrivance of a kind with which I was not entirely unfamiliar. This was a thin ladder of silken rope, having bamboo rungs, with two metal hooks for attaching it to any suitable object.

The one thus engaged was, as Karamaneh had declared, almost superhumanly thin. His loins were swathed in a sort of linen garment, and his head so bound about, turban fashion, that only his gleaming eyes remained visible. The bare limbs and body were of a dusky yellow color, and, at sight of him, I experienced a sudden nausea.

My pistol was in my cabin-trunk, and to have found it in the dark, without making a good deal of noise, would have been impossible.

Doubting how I should act, I stood watching the man with the swathed head whilst he threw the end of the ladder over the side, crept past the bow of the boat, and swung his gaunt body over the rail, exhibiting the agility of an ape. One quick glance fore and aft he gave, then began to swarm down the ladder: in which instant I knew his mission.

With a choking cry, which forced itself unwilled from my lips, I tore at the door, threw it open, and sprang across the deck. Plans, I had none, and since I carried no instrument wherewith to sever the ladder, the murderer might indeed have carried out his design for all that I could have done to prevent him, were it not that another took a hand in the game....

At the moment that the mummy-man--his head now on a level with the deck--perceived me, he stopped dead. Coincident with his stopping, the crack of a pistol shot sounded--from immediately beyond the boat.

Uttering a sort of sobbing sound, the creature fell--then clutched, with straining yellow fingers, at the rails, and, seemingly by dint of a great effort, swarmed along aft some twenty feet, with incredible swiftness and agility, and clambered onto the deck.

A second shot cracked sharply; and a voice (G.o.d! was I mad!) cried: "Hold him, Petrie!"

Rigid with fearful astonishment I stood, as out from the boat above me leaped a figure attired solely in shirt and trousers. The newcomer leaped away in the wake of the mummy-man--who had vanished around the corner by the smoke-room. Over his shoulder he cried back at me:

"The bishop's stateroom! See that no one enters!"

I clutched at my head--which seemed to be fiery hot; I realized in my own person the sensation of one who knows himself mad.

For the man who pursued the mummy was Nayland Smith!

I stood in the bishop's state-room, Nayland Smith, his gaunt face wet with perspiration, beside me, handling certain odd looking objects which littered the place, and lay about amid the discarded garments of the absent cleric.

"Pneumatic pads!" he snapped. "The man was a walking air-cushion!" He gingerly fingered two strange rubber appliances. "For distending the cheeks," he muttered, dropping them disgustedly on the floor. "His hands and wrists betrayed him, Petrie. He wore his cuff unusually long but he could not entirely hide his bony wrists. To have watched him, whilst remaining myself unseen, was next to impossible; hence my device of tossing a dummy overboard, calculated to float for less than ten minutes! It actually floated nearly fifteen, as a matter of fact, and I had some horrible moments!"

"Smith!" I said--"how could you submit me..."

He clapped his hands on my shoulders.

"My dear old chap--there was no other way, believe me. From that boat I could see right into his stateroom, but, once in, I dare not leave it--except late at night, stealthily! The second spotted me one night and I thought the game was up, but evidently he didn't report it."

"But you might have confided..."

"Impossible! I'll admit I nearly fell to the temptation that first night; for I could see into your room as well as into his!" He slapped me boisterously on the back, but his gray eyes were suspiciously moist.

"Dear old Petrie! Thank G.o.d for our friends! But you'd be the first to admit, old man, that you're a dead rotten actor! Your portrayal of grief for the loss of a valued chum would not have convinced a soul on board!

"Therefore I made use of Stacey, whose callous att.i.tude was less remarkable. Gad, Petrie! I nearly bagged our man the first night!

The elaborate plan--Marconi message to get you out of the way, and so forth--had miscarried, and he knew the porthole trick would be useless once we got into the open sea. He took a big chance. He discarded his clerical guise and peeped into your room--you remember?--but you were awake, and I made no move when he slipped back to his own cabin; I wanted to take him red-handed."

"Have you any idea..."

"Who he is? No more than where he is! Probably some creature of Dr.

Fu-Manchu specially chosen for the purpose; obviously a man of culture, and probably of thug ancestry. I hit him--in the shoulder; but even then he ran like a hare. We've searched the ship, without result. He may have gone overboard and chanced the swim to sh.o.r.e..."

We stepped out onto the deck. Around us was that unforgettable scene--Port Said by night. The ship was barely moving through the gla.s.sy water, now. Smith took my arm and we walked forward. Above us was the mighty peace of Egypt's sky ablaze with splendor; around and about us moved the unique turmoil of the clearing-house of the Near East.

"I would give much to know the real ident.i.ty of the bishop of Damascus,"

muttered Smith.

He stopped abruptly, snapping his teeth together and grasping my arm as in a vise. Hard upon his words had followed the rattling clangor as the great anchor was let go; but horribly intermingled with the metallic roar there came to us such a fearful, inarticulate shrieking as to chill one's heart.

The anchor plunged into the water of the harbor; the shrieking ceased.

Smith turned to me, and his face was tragic in the light of the arc lamp swung hard by.

"We shall never know," he whispered. "G.o.d forgive him--he must be in b.l.o.o.d.y tatters now. Petrie, the poor fool was hiding in the chainlocker!"

A little hand stole into mine. I turned quickly. Karamaneh stood beside me. I placed my arm about her shoulders, drawing her close; and I blush to relate that all else was forgotten.

For a moment, heedless of the fearful turmoil forward, Nayland Smith stood looking at us. Then he turned, with his rare smile, and walked aft.

"Perhaps you're right, Petrie!" he said.
