"Gentlemen," he said, "I have no impressions to impart. My mind is numbed. I had never hitherto appreciated the genius of Philip Gibbs...."

In the car Paul talked exclusively to Jules Thessaly, who had accompanied him upon his tour. Yvonne was silent. When first he had seen her awaiting him upon the platform his eyes had lighted up in that ardent way which she loved, and he had pressed her hands very hard in greeting. But thereafter he had become absorbed again in his giant dreams, and now as they sped through the London streets homeward, he bent forward, one hand resting upon Thessaly's knee, wrapped up in the companionship of his memories.

"That chateau, Thessaly, holds a secret which if it could be divulged to the world would revolutionise theology."

"Of what chateau do you speak?" asked Bassett.

"On my way to the French front I was entertained for a night at a wonderful old chateau. The devouring war had passed it by, and it stood like a dignified grand seigneur looking sorrowfully over the countryside. In order to understand how the sight of the place affected me you must know that as a boy I was several times visited by a certain dream. I last dreamed this dream during the time that I was at Oxford but I have never forgotten it. I used to find myself in a spacious salon, its appointments and fashion those of Louis Treize, with ghostly moonlight pouring in at lofty church-like windows and painting distorted shadowgraphs of heraldic devices upon the floor. My costume was that of a Cavalier and I held a long sword in my hand. I was conscious of pain and great weakness. Creeping stealthily from recess to recess, window to window, I would approach the double doors at the end of the salon. There I would pause, my heart throbbing fiercely, and press my ear to the gaily painted panels. A murmur of conversation would seem to proceed from the room beyond, but forced onward by some urgent necessity, the nature of which I could never recall upon awakening, I would suddenly throw the doors widely open and hurl myself into a small ante-room. A fire of logs blazed in the open hearth, and some six or eight musketeers lounged about the place, hats, baldrics, swords and cloaks lying discarded upon tables, chairs and where not. All sprang to their feet as I entered, and one, a huge red fellow, snatched up his sword and stood before a low door on the right of the room which I sought to approach. We crossed blades ... and with their metallic clash sounding in my ears I invariably awoke. I have spoken of this to you, Yvonne?"

Paul glanced rapidly at Yvonne but proceeded immediately without waiting for a reply. "As Thessaly and I were conducted to our rooms on the night of which I am speaking, I found myself traversing the salon of my dreams!"

"Most extraordinary," muttered Bassett. "Nothing about the aspect of the other rooms of the chateau had struck you as familiar?"

"Nothing; except that I was glad to be there. I cannot make clear to you the almost sorrowful veneration with which I entered the gate. It was like that of a wayward son who returns, broken, to the home upon which he has brought sorrow, to find himself welcomed by his first confessor, old, feeble, lonely, but filled with sweet compassion. I ascribed this emotion to the atmosphere of a stately home abandoned by its owners. But the salon revealed the truth to me. Heavy plush curtains were drawn across the windows, but the flames of three candles in a silver candelabra carried by the servant created just such a half-light as I remembered. I paused, questioning the accuracy of my recollections, but it was all real, unmistakable. We passed through the doorway at the end of the salon—and there was my guardroom! A modern stove had taken the place of the old open hearth, and the furniture was totally different, but I knew the room. The servant crossed before me to a door which I could not recall having noticed in my dream. As he opened it I looked to the right; and where the other door had been before which I had many times crossed swords with the red musketeer I saw a blank wall."

"It was no more than a very remarkable coincidence after all?" said Bassett.

"On the contrary. I called to the man, a bent old fellow, his face furrowed with age and heavy with care. 'Have you been long in the service of the family?' I asked him. His eyes glistened tearfully. 'Forty-five years, monsieur,' he answered. 'Then perhaps you can tell me if there was ever a door opening on the right, yonder, beside that armchair?'
