The terror of the irresistible impulse now never left Olva. He had told Bunning in a moment of uncontrol--what might he not do now at any time? At one instant to be absolutely silent seemed the only resource, at the next to rush out and take part in all the life about him. Were he silent he was tortured by the silence, if he flung himself amongst his fellow men every hour threatened self-betrayal. What, moreover, was happening in the house in Rocket Road? Craven was only waiting for certainty and at any moment some chance might give him what he needed. What did Mrs. Craven know? Margaret . . . Margaret . . . Margaret---Olva took the thought of her in his hand and held it like a sword, against the forces that were crowding in upon him. The afternoon of November 5 was thick with fog so that the shops were lighted early and every room was dim and unreal, and a sulphurous smell weighted the air. After "Hall" Olva came back to his room and found Bunning, his white face peering out of the foggy mist like a dull moon from clouds, waiting for him. All day there had hung about Olva heavy depression. It had seemed so ugly and sinister a world--the fog had been crowded with faces and terror, and the dreadful overpowering impression of unreality that had been increasing with every day now took from his companions all life and made of them grinning masks. He remembered Margaret's cry, "It is like walking in a dream," and echoed it. Surely it _was_ a dream! He would wake one happy morning and find that he had invited Craven and Carfax to breakfast, and he would hear them, whilst he dressed, talking together in the outer room, and, later, he would pass Bunning in the Court without knowing him. He would be introduced one day to Margaret Craven and find the house in which she lived a charming comfortable place, full of light and air, with a croquet lawn at the back of it, and Mrs. Craven, a nice ordinary middle-aged woman, stout possibly and fond of gossip. And instead of being President of the Wolves and a person of importance in the College he would be once again his old self, knowing nobody, scornful of the whole world and of the next world as well. And this brought him up with a terrible awakening. No, that old reality could never be real again, for that old reality meant a world without God. God had come and had turned the world into a nightmare . . . or was it only his rebellion against God that had so made it? But the nightmare was there, the awful uncertainty of every word, of every step, because with the slightest movement he might provoke the shadow to new action, if anything so grave, so stern, so silent as that Pursuit could be termed action, and . . . it was odd how certainly he knew it . . . so kind. Bunning's face brought him to the sudden necessity of treating the nightmare as reality, for the moment at any rate. The staring spectacles piteously appealed to him-- "I can't stand it--I can't stand it."
