His friends, when they had time to take stock of him, were rather shocked at his lorn appearance, and did their best to keep him up to the mark. Not altogether without success: but, when the two men were smoking alone later, Dunning became dull again. Suddenly he said, 'Gayton, I believe that alchemist man knows it was I who got his paper rejected.' Gayton whistled. 'What makes you think that?' he said. Dunning told of his conversation with the Museum assistant, and Gayton could only agree that the guess seemed likely to be correct. 'Not that I care much,' Dunning went on, 'only it might be a nuisance if we were to meet. He's a bad-tempered party, I imagine.' Conversation dropped again; Gayton became more and more strongly impressed with the desolateness that came over Dunning's face and bearing, and finally--though with a considerable effort--he asked him point-blank whether something serious was not bothering him. Dunning gave an exclamation of relief. 'I was perishing to get it off my mind,' he said. 'Do you know anything about a man named John Harrington?' Gayton was thoroughly startled, and at the moment could only ask why. Then the complete story of Dunning's experiences came out--what had happened in the tramcar, in his own house, and in the street, the troubling of spirit that had crept over him, and still held him; and he ended with the question he had begun with. Gayton was at a loss how to answer him. To tell the story of Harrington's end would perhaps be right; only, Dunning was in a nervous state, the story was a grim one, and he could not help asking himself whether there were not a connecting link between these two cases, in the person of Karswell. It was a difficult concession for a scientific man, but it could be eased by the phrase 'hypnotic suggestion'. In the end he decided that his answer tonight should be guarded; he would talk the situation over with his wife. So he said that he had known Harrington at Cambridge, and believed he had died suddenly in 1889, adding a few details about the man and his published work. He did talk over the matter with Mrs Gayton, and, as he had anticipated, she leapt at once to the conclusion which had been hovering before him. It was she who reminded him of the surviving brother, Henry Harrington, and she also who suggested that he might be got hold of by means of their hosts of the day before. 'He might be a hopeless crank,' objected Gayton. 'That could be ascertained from the Bennetts, who knew him,' Mrs Gayton retorted; and she undertook to see the Bennetts the very next day.
It is not necessary to tell in further detail the steps by which Henry Harrington and Dunning were brought together.
