The two went down to the harbor, and finding the sailor waiting with the boat at the steps, were rowed to the yacht and got on board. Here the two men were all alone. Then, with a preliminary clearing of his voice, Castleton began his story:
“Frank Onslow—better get the worst over at once—just after you went away from Harrogate your wife was tried for murder and acquitted.”
“My God! Fenella tried for murder? Whose murder?”
“That scoundrel De Mürger. It seems he went into her room in the night and attempted violence, so she stabbed him——”
Castleton stopped in amazement, for a look of radiance came over Frank Onslow’s face, as he murmured “Thank God!” Recalled to himself by Castleton’s silence, for he was too amazed to go on, Frank said: “I have a reason, old fellow; I shall tell it to you later, but go on. Tell me all the facts, or let me read the papers. Remember I am as yet quite ignorant of it all and I am full of anxiety!”
Without a word Castleton handed him the papers, and, lighting a fresh cigar, sat down with his back to him, and presently yielded to the sun and fresh air and fell into a doze.
Frank Onslow took the papers, and read carefully from end to end the account of the trial of his wife for the murder of De Mürger. When he had finished he sat with the folded paper in his hand, and his eyes had the same far-away look in them which they had had on that fatal night. The hypnotic trance was on him again.
Presently he rose, and with stealthy steps approached his sleeping friend. Murmuring “Why did I not kill him?” he struck with the folded paper, as though with a dagger, the form before him. Castleton, who had sunk into a pleasant sleep and whose fat face was wreathed with a smile, was annoyed at the rude awakening. “What the devil!” he began angrily, and then stopped as his eyes met the face of his friend and he realized that he was in some sort of trance. He grew very pale as he saw Frank Onslow stab, and stab, and stab again. There was a certain grotesqueness in the affair—the man in such terrible earnest, in his mind committing murder, while his real weapon was but a folded paper. As he stabbed he hissed, “Why did I not kill him? Why did I not kill him?” Then he went through a series of movements as though he were softly pulling an imaginary door shut behind him, and so back to his own chair, where he sat down hiding his face in his hands.
Castleton sat looking at him in amazement, and then murmured to himself:
“They thought it was someone stronger than Fenella whose grasp made those marks on the dead man’s throat.” He suddenly looked round to see that no one but himself had observed what had happened, and then, being satisfied on this point, murmured again:
