She looked at him sadly in her first experience of masculine incomprehension of woman’s exaltation of sacrifice in love, but she did not speak. He continued. “But we must think of what’s to be done.” He walked up and down the room again, considering this question with compressed brows. He stopped, struck by a thought, and looked at her. “The police have been trying to find out from Thalassa whether you went back to Flint House that night, but he will not tell them anything. So they suspect him also.”
She roused at that. “Oh, they must not!” she cried in distress. “Poor Thalassa! He must tell them the truth.”
“The question is—what is the truth?” It flashed through his mind as he spoke that his interrogation was the echo of one put to him by his father before he left Cornwall.
“The truth is, that Thalassa and I left the house together that night before it happened. Oh, cannot they believe that? Cannot it be proved?”
“I could tell them when you left,” he said in a low tone.
“You!” she cried, looking at him with a kind of fear. “How do you know?”
“Because I saw you. I was standing outside, close to the house.”
“Why were you there?” she put in quickly.
He was slower in answering. “I had gone to see your father—about you. I was standing there, thinking … waiting, when the front door opened, and you and Thalassa came out. I was surprised to see you, but it seemed to me an opportunity—a final chance—to speak to you again. I started after you, Sisily, once more to ask you to consider my love for you, but you and Thalassa were swallowed up in the darkness of the moors before I could reach you. I followed with the intention of overtaking you, but I got lost on the moors instead, and was wandering about in the blackness for nearly half an hour before I found my way back to Flint House again.”
“Could you not tell them—the police—that?” she asked, a little wistfully.
