Nigel had a sudden inspiration.

"You are seeking to bribe Maggie!" he exclaimed.

"That is not true," was the dignified reply.

"Then please explain," Nigel persisted.

Prince Shan rose to his feet. He walked to the heavy silk curtains which led into his own bedchamber, pushed them apart, and looked for a moment at the familiar objects in the room. Then he came back, glancing on his way at the ebony cabinet.

"One does not repeat one's mistakes," he said slowly, "and although you and I, Lord Dorminster, breathe the common air of the greater world, my instinct tells me that of certain things which have pa.s.sed between your cousin and myself it is better that no mention ever be made. I wish to tell you this, however. There is in existence a doc.u.ment, my signature to which would, without a doubt, have a serious influence upon the destinies of this country. That doc.u.ment, unsigned, would be one of my marriage gifts to Lady Maggie--and as you know I have not yet had her answer. However, if you wish it, I will go to the Prime Minister."

Li Wen came silently in. He spoke to his master for a few minutes in Chinese. A faint smile parted the latter's lips.

"You can tell the person at the telephone that I will call within the next few minutes," he directed. "You will not object," he added, turning courteously to Nigel, "if I stop for a moment, on the way to Downing Street, at a small private hospital? An acquaintance of mine lies sick there and desires urgently to see me."

"I am entirely at your service," Nigel a.s.sured him.

Prince Shan, with many apologies, left Nigel alone in the car outside a tall, grey house in John Street, and, preceded by the white-capped nurse who had opened the door, climbed the stairs to the first floor of the celebrated nursing home, where, after a moment's delay, he was shown into a large and airy apartment. Immelan was in bed, looking very ill indeed. He was pale, and his china-blue eyes, curiously protruding, were filled with an expression of haunting fear. A puzzled doctor was standing by the bedside. A nurse, who was smoothing the bedclothes, glanced around at Prince Shan's entrance. The invalid started convulsively, and, clutching the pillows with his right hand, turned towards his visitor.

"So you've come!" he exclaimed. "Stay where yon are! Don't go!

Doctor--nurse--leave us alone for a moment."

The nurse went at once. The doctor hesitated.

"My patient is a good deal exhausted," he said. "There are no dangerous symptoms at present, but--"

"I will promise not to distress him," Prince Shan interrupted. "I am myself somewhat pressed for time, and it is probable that your patient will insist upon speaking to me in private."

The doctor followed the nurse from the room. Prince Shan stood looking down upon the figure of quondam a.s.sociate. There was a leaven of mild wonder in his clear eyes, a faintly contemptuous smile about the corners of his lips.

"So you are afraid of death, my friend," he observed, "afraid of the death you planned so skilfully for me."

"It is a lie!" Immelan declared excitedly. "Sen Lu was never killed by my orders. Listen! You have nothing against me. My death can do you no good. It is you who have been at fault. You--Prince Shan--the great diplomatist of the world--are gambling away your future and the future of a mighty empire for a woman's sake. You have treated me badly enough.

Spare my life. Call in the doctor here and tell him what to do. He can find nothing in my system. He is helpless."

The smile upon the Prince's lips became vaguer, his expression more bland and indeterminate.

"My dear Immelan," he murmured, "you are without doubt delirious.

Compose yourself, I beg."

A light that was almost tragic shone in the man's face. He sat up with a sudden access of strength.

"For the love of G.o.d, don't torture me!" he groaned. "The pains grow worse, hour by hour. If I die, the whole world shall know by whose hand."

The expression on Prince Shan's face remained unchanged. In his eyes, however, there was a little glint of something which seemed almost like foreknowledge,

"When you die," he p.r.o.nounced calmly, "it will be by your own hand--not mine."

For some reason or other, Immelan accepted these measured words of prophecy as a total reprieve. The relief in his face was almost piteous.

He seized his visitor's hand and would have fawned upon it. Prince Shan withdrew himself a little farther from the bed.

"Immelan," he said, "during my stay in England I have studied you and your methods, I have listened to all you have had to say and to propose, I have weighed the advantages and the disadvantages of the scheme you have outlined to me, and I only arrived at my decision after the most serious and unbia.s.sed reflection. Your scheme itself was bold and almost splendid, but, as you yourself well know at the back of your mind, it would lay the seeds of a world tumult. I have studied history, Immelan, perhaps a little more deeply than you, and I do not believe in conquests. For the restoration to China of such lands as belong geographically and rightly to the Chinese Empire, I have my own plans.

You, it seems to me, would make a cat's-paw of all Asia to gratify your hatred of England."

"A cat's-paw!" Immelan gasped. "Australia, New Zealand and India for j.a.pan, new lands for her teeming population; Thibet for you, all Manchuria, and the control of the Siberian Railway!"

"These are dazzling propositions," Prince Shan admitted, "and yet--what about the other side of the Pacific?"

"America would be powerless," Immelan insisted.

"So you said before, in 1917," was the dry reminder. "I did not come here, however, to talk world politics with you. Those things for the moment are finished. I came in answer to your summons."

Immelan raised himself a little in the bed.

"You meant what you said?" he demanded, with hoa.r.s.e anxiety. "There was no poison? Swear that?"

Prince Shan moved towards the door. His backward glance was coldly contemptuous.

"What I said, I meant," he replied. "Extract such comfort from it as you may."

He left the room, closing the door softly behind him. Immelan stared after him, hollow-eyed and anxious. Already the cold fears were seizing upon him once more.

Prince Shan rejoined Nigel, and the two men drove off to Downing Street.

The former was silent for the first few minutes. Then he turned slightly towards his companion.

"The man Immelan is a coward," he declared. "It is he whom I have just visited."

Nigel shrugged his shoulders.

"So many men are brave enough in a fight," he remarked, "who lose their nerve on a sick bed."

"Bravery in battle," Prince Shan p.r.o.nounced, "is the lowest form of courage. The blood is stirred by the excitement of slaughter as by alcohol. With Immelan I shall have no more dealings."

"Speaking politically as well as personally?" Nigel enquired.

The other smiled.

"I think I might go so far as to agree," he acquiesced, "but in a sense, there are conditions. You shall hear what they are. I will speak before you to the Prime Minister. See, up above is the sign of my departure."

Out of a little bank of white, fleecy clouds which hung down, here and there, from the blue sky, came the _Black Dragon_, her engines purring softly, her movements slow and graceful. Both men watched her for a moment in silence.

"At six o'clock to-morrow morning I start," Prince Shan announced. "My pilot tells me that the weather conditions are wonderful, all the way from here to Pekin. We shall be there on Wednesday."

"You travel alone?" Nigel enquired.

"I have pa.s.sengers," was the quiet reply. "I am taking the English chaplain to your Church in Pekin."

The eyes of the two men met.
