Above, the liquid orange sky; beneath, this sweet, subdued ecstasy of bells.

"_Alma Redemptoris Mater_," whispered Percy, his eyes wet with tears.

"_Gentle Mother of the Redeemer--the open door of the sky, star of the sea--have mercy on sinners. _The Angel of the Lord announced it to Mary, and she conceived of the Holy Ghost_.... Pour, therefore, Lord, Thy grace into our hearts. Let us, who know Christ's incarnation, rise through passion and cross to the glory of Resurrection--through the same Christ our Lord."

Another bell clanged sharply close at hand, calling him down to earth, and wrong, and labour and grief; and he turned to see the motionless volor itself one blaze of brilliant internal light, and the two priests following the German Cardinal across the gangway.

It was the rear compartment that the men had taken; and when he had seen that the old man was comfortable, still without a word he passed out again into the central passage to see the last of Rome.

The exit-door had now been snapped, and as Percy stood at the opposite window looking out at the high wall that would presently sink beneath him, throughout the whole of the delicate frame began to run the vibration of the electric engine. There was the murmur of talking somewhere, a heavy step shook the floor, a bell clanged again, twice, and a sweet wind-chord sounded. Again it sounded; the vibration ceased, and the edge of the high wall against the tawny sky on which he had fixed his eyes sank suddenly like a dropped bar, and he staggered a little in his place. A moment later the dome rose again, and itself sank, the city, a fringe of towers and a mass of dark roofs, pricked with light, span like a whirlpool; the jewelled stars themselves sprang this way and that; and with one more long cry the marvellous machine righted itself, beat with its wings, and settled down, with the note of the flying air passing through rising shrillness into vibrant silence, to its long voyage to the north.

Further and further sank the city behind; it was a patch now: greyness on black. The sky seemed to grow more huge and all-containing as the earth relapsed into darkness; it glowed like a vast dome of wonderful glass, darkening even as it glowed; and as Percy dropped his eyes once more round the extreme edge of the car the city was but a line and a bubble--a line and a swelling--a line, and nothingness.

He drew a long breath, and went back to his friends.

"Tell me again," said the old Cardinal, when the two were settled down opposite to one another, and the chaplains were gone to another compartment. "Who is this man?"

"This man? He was secretary to Oliver Brand, one of our politicians. He fetched me to old Mrs. Brand's death bed, and lost his place in consequence. He is in journalism now. He is perfectly honest. No, he is not a Catholic, though he longs to be one. That is why they confided in him."

"And they?"

"I know nothing of them, except that they are a desperate set. They have enough faith to act, but not enough to be patient.... I suppose they thought this man would sympathise. But unfortunately he has a conscience, and he also sees that any attempt of this kind would be the last straw on the back of toleration. Eminence, do you realise how violent the feeling is against us?"

The old man shook his head lamentably.

"Do I not?" he murmured. "And my Germans are in it? Are you sure?"

"Eminence, it is a vast plot. It has been simmering for months. There have been meetings every week. They have kept the secret marvellously.

Your Germans only delayed that the blow might be more complete. And now, to-morrow---" Percy drew back with a despairing gesture.

"And the Holy Father?"

"I went to him as soon as mass was over. He withdrew all opposition, and sent for you. It is our one chance, Eminence."

"And you think our plan will hinder it?"

"I have no idea, but I can think of nothing else. I shall go straight to the Archbishop and tell him all. We arrive, I believe, at three o'clock, and you in Berlin about seven, I suppose, by German time. The function is fixed for eleven. By eleven, then, we shall have done all that is possible. The Government will know, and they will know, too, that we are innocent in Rome. I imagine they will cause it to be announced that the Cardinal-Protector and the Archbishop, with his coadjutors, will be present in the sacristies. They will double every guard; they will parade volors overhead--and then--well! in God's hands be the rest."

"Do you think the conspirators will attempt it?"

"I have no idea," said Percy shortly.

"I understand they have alternative plans."

"Just so. If all is clear, they intend dropping the explosive from above; if not, at least three men have offered to sacrifice themselves by taking it into the Abbey themselves.... And you, Eminence?"

The old man eyed him steadily.

"My programme is yours," he said. "Eminence, have you considered the effect in either case? If nothing happens---"

"If nothing happens we shall be accused of a fraud, of seeking to advertise ourselves. If anything happens--well, we shall all go before God together. Pray God it may be the second," he added passionately.

"It will be at least easier to bear," observed the old man.

"I beg your pardon, Eminence. I should not have said that."

There fell a silence between the two, in which no sound was heard but the faint untiring vibration of the screw, and the sudden cough of a man in the next compartment. Percy leaned his head wearily on his hand, and stared from the window.

The earth was now dark beneath them--an immense emptiness; above, the huge engulfing sky was still faintly luminous, and through the high frosty mist through which they moved stars glimmered now and again, as the car swayed and tacked across the wind.

"It will be cold among the Alps," murmured Percy. Then he broke off.

"And I have not one shred of evidence," he said; "nothing but the word of a man."

"And you are sure?"

"I am sure."

"Eminence," said the German suddenly, staring straight into his face, "the likeness is extraordinary."

Percy smiled listlessly. He was tired of bearing that.

"What do you make of it?" persisted the other.

"I have been asked that before," said Percy. "I have no views."

"It seems to me that God means something," murmured the German heavily, still staring at him.

"Well, Eminence?"

"A kind of antithesis--a reverse of the medal. I do not know."

Again there was silence. A chaplain looked in through the glazed door, a homely, blue-eyed German, and was waved away once more.

"Eminence," said the old man abruptly, "there is surely more to speak of. Plans to be made."

Percy shook his head.

"There are no plans to be made," he said. "We know nothing but the fact--no names--nothing. We--we are like children in a tiger's cage. And one of us has just made a gesture in the tiger's face."

"I suppose we shall communicate with one another?"

"If we are in existence."

It was curious how Percy took the lead. He had worn his scarlet for about three months, and his companion for twelve years; yet it was the younger who dictated plans and arranged. He was scarcely conscious of its strangeness, however. Ever since the shocking news of the morning, when a new mine had been sprung under the shaking Church, and he had watched the stately ceremonial, the gorgeous splendour, the dignified, tranquil movements of the Pope and his court, with a secret that burned his heart and brain--above all, since that quick interview in which old plans had been reversed and a startling decision formed, and a blessing given and received, and a farewell looked not uttered--all done in half-an-hour--his whole nature had concentrated itself into one keen tense force, like a coiled spring. He felt power tingling to his finger-tips--power and the dulness of an immense despair. Every prop had been cut, every brace severed; he, the City of Rome, the Catholic Church, the very supernatural itself, seemed to hang now on one single thing--the Finger of God. And if that failed--well, nothing would ever matter any more....
