Mr. Playmore's last prophetic words were vividly present to my mind. He had declared, in the most positive manner, that Dexter would persist in misleading me, and would show no signs of astonishment when I repeated what Lady Clarinda had told me of Mrs. Beauly. I resolved to put the lawyer's prophecy--so far as the question of astonishment was concerned--to the sharpest attainable test. I said not a word to Miserrimus Dexter in the way of preface or preparation: I burst on him with my news as abruptly as possible.
"The person you saw in the corridor was not Mrs. Beauly," I said. "It was the maid, dressed in her mistress's cloak and hat. Mrs. Beauly herself was not in the house at all. Mrs. Beauly herself was dancing at a masked ball in Edinburgh. There is what the maid told Lady Clarinda; and there is what Lady Clarinda told me."
In the absorbing interest of the moment, I poured out those words one after another as fast as they would pass my lips. Miserrimus Dexter completely falsified the lawyer's prediction. He shuddered under the shock. His eyes opened wide with amazement. "Say it again!" he cried. "I can't take it all in at once. You stun me."
I was more than contented with this result--I triumphed in my victory. For once, I had really some reason to feel satisfied with myself. I had taken the Christian and merciful side in my discussion with Mr. Playmore; and I had won my reward. I could sit in the same room with Miserrimus Dexter, and feel the blessed conviction that I was not breathing the same air with a poisoner. Was it not worth the visit to Edinburgh to have made sure of that?
In repeating, at his own desire, what I had already said to him, I took care to add the details which made Lady Clarinda's narrative coherent and credible. He listened throughout with breathless attention--here and there repeating the words after me, to impress them the more surely and the more deeply on his mind.
"What is to be said? what is to be done?" he asked, with a look of blank despair. "I can't disbelieve it. From first to last, strange as it is, it sounds true."
(How would Mr. Playmore have felt if he had heard those words? I did him the justice to believe that he would have felt heartily ashamed of himself.) "There is nothing to be said," I rejoined, "except that Mrs. Beauly is innocent, and that you and I have done her a grievous wrong. Don't you agree with me?"
