"But, Smith, I saw you drink some port."

"I regret to contradict you, Petrie, but you must be aware that the state of my liver--due to a long residence in Burma--does not permit me to indulge in the luxury of port. My share of the '45 now reposes amid the moss in the tulip-bowl, which you may remember decorated the dining table! Not desiring to appear churlish, by means of a simple feat of legerdemain I drank your health and future happiness in claret!

"For G.o.d's sake what is going on, Smith? Some one climbed from your window."

"I climbed from my window!"

"What!" I said dazedly--"it was you! But what does it all mean?

Karamaneh----"

"It is for her I fear, Petrie, now. We have not a moment to waste!"

He made for the door.

"Sir Lionel must be warned at all cost!" I cried.

"Impossible!" snapped Smith.

"What do you mean?"

"Sir Lionel has disappeared!"

CHAPTER x.x.xVI

THE DUNGEON

We were out in the corridor now, Smith showing the way with the light of his electric pocket-lamp. My mind was clear enough, but I felt as weak as a child.

"You look positively ghastly, old man," rapped Smith, "which is no matter for wonder. I have yet to learn how it happened that you are not lying insensible, or dead, as a result of the drugged wine. When I heard some one moving in your room, it never occurred to me that it was _you_."

"Smith," I said--"the house seems as still as death."

"You, Karamaneh, and myself are the only occupants of the east wing.

h.o.m.opoulo saw to that."

"Then he----"

"He is a member of the Si-Fan, a creature of Dr. Fu-Manchu--yes, beyond all doubt! Sir Lionel is unfortunate--as ever--in his choice of servants. I blame my own stupidity entirely, Petrie; and I pray that my enlightenment has not come too late."

"What does it all mean?--what have you learnt?"

"Mind these three steps," warned Smith, glancing back. "I found my mind persistently dwelling upon the matter of that weird rapping, Petrie, and I recollected the situation of Sir Lionel's room, on the southeast front. A brief inspection revealed the fact that, by means of a kindly branch of ivy, I could reach the roof of the east tower from my window."

"Well?"

"One may walk from there along the roof of the southeast front, and by lying face downwards at the point where it projects above the main entrance look into Sir Lionel's room!"

"I saw you go!"

"I feared that some one was watching me, but that it was you I had never supposed. Neither Barton nor his man are in that room, Petrie!

They have been spirited away! This is Karamaneh's door."

He grasped me by the arm, at the same time directing the light upon a closed door before which we stood. I raised my fist and beat upon the panels; then, every muscle tensed and my heart throbbing wildly, I listened for the girl's voice.

Not a sound broke that deathly stillness except the beating of my own heart, which, I thought, must surely be audible to my companion.

Frantically I hurled myself against the stubborn oak, but Smith thrust me back.

"Useless, Petrie!" he said--"useless. This room is in the base of the east tower, yours is above it and mine at the top. The corridors approaching the three floors deceive one, but the fact remains. I have no positive evidence, but I would wager all I possess that there is a stair in the thickness of the wall, and hidden doors in the paneling of the three apartments. The Yellow group has somehow obtained possession of a plan of the historic secret pa.s.sages and chambers of Graywater Park. h.o.m.opoulo is the spy in the household; and Sir Lionel, with his man Kennedy, was removed directly the invitation to us had been posted. The group will know by now that we have escaped them, but Karamaneh ..."

"Smith!" I groaned, "Smith! What can we do? What has befallen her? ..."

"This way!" he snapped. "We are not beaten yet!"

"We must arouse the servants!"

"Why? It would be sheer waste of priceless time. There are only three men who actually sleep in the house (excepting h.o.m.opoulo) and these are in the northwest wing. No, Petrie; we must rely upon ourselves."

He was racing recklessly along the tortuous corridors and up the oddly placed stairways of that old-world building. My anguish had reinforced the atropine which I had employed as an antidote to the opiate in the wine, and now my blood, that had coursed sluggishly, leapt through my veins like fire and I burned with a pa.s.sionate anger.

Into a large and untidy bedroom we burst. Books and papers littered about the floor; curios, ranging from mummied cats and ibises to Turkish yataghans and Zulu a.s.segais, surrounded the place in riotous disorder. Beyond doubt this was the apartment of Sir Lionel Barton.

A lamp burned upon a table near to the disordered bed, and a discolored Greek statuette of Orpheus lay overturned on the carpet close beside it.

"h.o.m.opoulo was on the point of leaving this room at the moment that I peered in at the window," said Smith, breathing heavily. "From here there is another entrance to the secret pa.s.sages. Have your pistol ready."

He stepped across the disordered room to a little alcove near the foot of the bed, directing the ray of the pocket-lamp upon the small, square paneling.

"Ah!" he cried, a note of triumph in his voice--"he has left the door ajar! A visit of inspection was not antic.i.p.ated to-night, Petrie!

Thank G.o.d for an Indian liver and a suspicious mind."

He disappeared into a yawning cavity which now I perceived to exist in the wall. I hurried after him, and found myself upon roughly fashioned stone steps in a very low and narrow descending pa.s.sage. Over his shoulder--

"Note the direction," said Smith breathlessly. "We shall presently find ourselves at the base of the east tower."

Down we went and down, the ray of the electric lamp always showing more steps ahead, until at last these terminated in a level, arched pa.s.sage, curving sharply to the right. Two paces more brought us to a doorway, less, than four feet high, approached by two wide steps. A blackened door, having a most c.u.mbersome and complicated lock, showed in the recess.

Nayland Smith bent and examined the mechanism intently.

"Freshly oiled!" he commented. "You know into whose room it opens?"

Well enough I knew, and, detecting that faint, haunting perfume which spoke of the dainty personality of Karamaneh, my anger blazed up anew. Came a faint sound of metal grating upon metal, and Smith pulled open the door, which turned outward upon the steps, and bent further forward, sweeping the ray of light about the room beyond.

"Empty, of course!" he muttered. "Now for the base of these d.a.m.ned nocturnal operations."

He descended the steps and began to flash the light all about the arched pa.s.sageway wherein we stood.

"The present dining-room of Graywater Park lies almost due south of this spot," he mused. "Suppose we try back."
