'Your ladyship now sees that you fell into a natural error,' continued Kelly, who was anxious to smooth Lady Oxford's path, 'in consequence of which you took a natural revenge. May I ask how you secured the means of revenge? How, in a word, you came to know of the hidden Plot within the Plot?'

Her ladyship's answer fairly startled Mr. Kelly. It was not given at once. She still played with the cards, and overturned another. It was the knave of clubs.

'The cards tell you,' she said with a bitter smile.

Mr. Kelly leaned back in his chair open-mouthed. 'Scrope?' he asked.

'Scrope,' replied her ladyship. 'I received a humble letter from him praying that I would forgive his odious ingratitude, and, by way of peace-offering, bidding me tell my Lord Oxford--'

'Who had already withdrawn,' said George. 'I think I understand,' Lady Oxford's look of humiliation had enlightened him, 'and I think your ladyship understands with me. Mr. Scrope is a sort of a gentleman, and would prefer to do his dirty work without appearing as a spy. He has made use of your ladyship. He sends you the Plot and spurs you to disclose it with his ballad. He would have disclosed it himself, I doubt not, had not your ladyship served his turn. But Mr. Scrope has his refinements, and, besides that he spares himself, would take a particular pleasure in compassing my ruin at the same time that he outwitted you.'

Little wonder that Lady Oxford broke in upon Mr. Kelly's reasonings. It must have been sufficiently galling for her to reflect that in exacting her revenge she had been the mere instrument of a man she had tossed aside.

'It is both of us that he has ruined, not you alone,' she cried.

Certainly, Mr. Scrope was a person to reckon with, and had killed quite a covey of birds with one stone.

'Are you sure?' asked Kelly. 'Are you sure of that?'
