"Are you? Why is that?" "I shall probably tell you in a day or two." The Father took his cup again. He did not press Guildea for an immediate explanation, but when they had both finished their tea he said: "Well, has the sea-air had the desired effect?" "No," said Guildea. The Father brushed some crumbs from the front of his cassock and sat up higher in his chair. "Your visitor is still here?" he asked, and his blue eyes became almost ungentle and piercing as he gazed at his friend. "Yes," answered Guildea, calmly. "How do you know it, when did you know it--when you looked into the dining-room just now?" "No. Not until I came into this room. It welcomed me here." "Welcomed you! In what way?" "Simply by being here, by making me feel that it is here, as I might feel that a man was if I came into the room when it was dark." He spoke quietly, with perfect composure in his usual dry manner. "Very well," the Father said, "I shall not try to contend against your sensation, or to explain it away. Naturally, I am in amazement." "So am I. Never has anything in my life surprised me so much. Murchison, of course I cannot expect you to believe more than that I honestly suppose--imagine, if you like--that there is some intruder here, of what kind I am totally unaware. I cannot expect you to believe that there really is anything. If you were in my place, I in yours, I should certainly consider you the victim of some nervous delusion. I could not do otherwise. But--wait. Don't condemn me as a hysteria patient, or as a madman, for two or three days. I feel convinced that--unless I am indeed unwell, a mental invalid, which I don't think is possible--I shall be able very shortly to give you some proof that there is a newcomer in my house." "You don't tell me what kind of proof?" "Not yet. Things must go a little farther first. But, perhaps even to-morrow I may be able to explain myself more fully. In the meanwhile, I'll say this, that if, eventually, I can't bring any kind of proof that I'm not dreaming I'll let you take me to any doctor you like, and I'll resolutely try to adopt your present view--that I'm suffering from an absurd delusion. That is your view of course?" Father Murchison was silent for a moment. Then he said, rather doubtfully: "It ought to be." "But isn't it?" asked Guildea, surprised. "Well, you know, your manner is enormously convincing. Still, of course, I doubt. How can I do otherwise? The whole thing must be fancy." The Father spoke as if he were trying to recoil from a mental position he was being forced to take up. "It must be fancy," he repeated. "I'll convince you by more than my manner, or I'll not try to convince you at all," said Guildea. When they parted that evening, he said, "I'll write to you in a day or two probably. I think the proof I am going to give you has been accumulating during my absence. But I shall soon know."
