“Since my reason for suppressing that information was all a fantasy, why did you never make any use of it? When I began to realize that I had been wrong about you, I explained your silence to myself by saying that you could not bring yourself to do a thing that would put a rope round a man’s neck, whatever he might have done. I can quite understand that feeling. Was that what it was? Another possibility I thought of was that you knew of something that was by way of justifying or excusing Marlowe’s act. Or I thought you might have a simple horror, quite apart from humanitarian scruples, of appearing publicly in connection with a murder trial. Many important witnesses in such cases have to be practically forced into giving their evidence. They feel there is defilement even in the shadow of the scaffold.” Mrs. Manderson tapped her lips with the envelope without quite concealing a smile. “You didn’t think of another possibility, I suppose, Mr. Trent,” she said. “No.” He looked puzzled. “I mean the possibility of your having been wrong about Mr. Marlowe as well as about me. No, no; you needn’t tell me that the chain of evidence is complete. I know it is. But evidence of what? Of Mr. Marlowe having impersonated my husband that night, and having escaped by way of my window, and built up an alibi. I have read your dispatch again and again, Mr. Trent, and I don’t see that those things can be doubted.” Trent gazed at her with narrowed eyes. He said nothing to fill the brief pause that followed. Mrs. Manderson smoothed her skirt with a preoccupied air, as one collecting her ideas. “I did not make any use of the facts found out by you,” she slowly said at last, “because it seemed to me very likely that they would be fatal to Mr. Marlowe.” “I agree with you,” Trent remarked in a colourless tone. “And,” pursued the lady, looking up at him with a mild reasonableness in her eyes, “as I knew that he was innocent I was not going to expose him to that risk.” There was another little pause. Trent rubbed his chin, with an affectation of turning over the idea. Inwardly he was telling himself, somewhat feebly, that this was very right and proper; that it was quite feminine, and that he liked her to be feminine. It was permitted to her—more than permitted—to set her loyal belief in the character of a friend above the clearest demonstrations of the intellect. Nevertheless, it chafed him. He would have had her declaration of faith a little less positive in form. It was too irrational to say she “knew”. In fact (he put it to himself bluntly), it was quite unlike her. If to be unreasonable when reason led to the unpleasant was a specially feminine trait, and if Mrs. Manderson had it, she was accustomed to wrap it up better than any woman he had known.
