A thousand times, with a heart full of anguish, he had sought to reason away the dread that Mabel Manderson had known too much of what had been intended against her husband's life. That she knew all the truth after the thing was done, he could not doubt; her unforgettable collapse in his presence when the question about Marlowe was suddenly and bluntly put had swept away his last hope that there was no love between the pair, and had seemed to him, moreover, to speak of dread of discovery. In any case, she knew the truth after reading what he had left with her; and it was certain that no public suspicion had been cast upon Marlowe since. She had destroyed his manuscript, then, and taken him at his word to keep the secret that threatened her lover's life. But it was the monstrous thought that she might have known murder was brewing, and guiltily kept silence, that haunted Trent's mind. She might have suspected, have guessed something; was it conceivable that she was aware of the whole plot, that she connived? He could never forget that his first suspicion of Marlowe's motive in the crime had been roused by the fact that his escape was made through the lady's room. At that time, when he had not yet seen her, he had been ready enough to entertain the idea of her equal guilt and her cooeperation. He had figured to himself some passionate _hysterique_, merciless as a tiger in her hate and her love, a zealous abettor, perhaps even the ruling spirit in the crime. Then he had seen her, had spoken with her, had helped her in her weakness; and such suspicions, since their first meeting, had seemed the vilest of infamy. He had seen her eyes and her mouth; he had breathed the woman's atmosphere. Trent was one of those who fancy they can scent true wickedness in the air. In her presence he had felt an inward certainty of her ultimate goodness of heart; and it was nothing against this, that she had abandoned herself a moment, that day on the cliff, to the sentiment of relief at the ending of her bondage, of her years of starved sympathy and unquickened motherhood. That she had turned to Marlowe in her destitution he believed; that she had any knowledge of his deadly purpose he did not believe.
