"You say that Chaldea holds a letter which inveigled my husband to his death?" demanded Lady Agnes coolly.
"Yes. And she wants five thousand pounds for it."
"Why doesn"t she give it to the police?"
"One thousand pounds is not enough for the letter. It is worth more--to some people," and Silver raised his pale eyes again.
"To me, I presume you mean;" then when he bowed, she continued her examination. "The five thousand pounds you intimate is on account, yet you say that Chaldea will deliver the letter for that sum."
"To me," rejoined the ex-secretary impudently. "And when it is in my possession, I can give it to you for twenty thousand pounds."
Lady Agnes laughed in his face. "I am too good a business woman to make such a bargain," she said with a shrug.
"Well, you know best," replied Silver, imitating her shrug.
"I know nothing; I am quite in the dark as to the reason for your blackmailing, Mr. Silver."
"That is a nasty word, Lady Agnes."
"It is the only word which seems to suit the situation. Why should I give twenty-five thousand pounds for this letter?"
"Its production will place the police on the track of the a.s.sa.s.sin."
"And is not that what I desire? Why did I offer a reward of one thousand pounds if I did not hope that the wretch who murdered my husband should be brought to justice?"
Silver exhibited unfeigned surprise. "You wish that?"
"Certainly I do. Where was this letter discovered?"
"Chaldea went to the tent of your husband in the camp and found it in the pocket of his coat. He apparently left it behind by mistake when he went to watch."
"Watch?"
"Yes! The letter stated that you intended to elope that night with Mr.
Lambert, and would leave the house by the blue door. Sir Hubert went to watch and prevent the elopement. In that way he came by his death, since Lord Garvington threatened to shoot a possible burglar. Of course, Sir Hubert, when the blue door was opened by Lord Garvington, who had heard the footsteps of the supposed burglar, threw himself forward, thinking you were coming out to meet Mr. Lambert. Sir Hubert was first shot in the arm by Lord Garvington, who really believed for the moment that he had to do with a robber. But the second shot," ended Silver with emphasis, "was fired by a person concealed in the shrubbery, who knew that Sir Hubert would walk into the trap laid by the letter."
During this amazing recital, Lady Agnes, with her eyes on the man"s face, and her hands clasped in sheer surprise, had sat down on a near couch. She could scarcely believe her ears. "Is this true?" she asked in a faltering voice.
Silver shrugged his shoulders again. "The letter held by Chaldea certainly set the snare in which Sir Hubert was caught. Unless the person in the shrubbery knew about the letter, the person would scarcely have been concealed there with a revolver. I know about the letter for certain, since Chaldea showed it to me, when I went to ask questions about the murder in the hope of gaining the reward. The rest of my story is theoretical."
"Who was the person who fired the shot?" asked Lady Agnes abruptly.
"I don"t know."
"Who wrote the letter which set the snare?"
Silver shuffled. "Chaldea loves Mr. Lambert," he said hesitating.
"Go on," ordered the widow coldly and retaining her self-control.
"She is jealous of you, Lady Agnes, because--"
"There is no reason to explain," interrupted the listener between her teeth.
"Well, then, Chaldea hating you, says that you wrote the letter."
"Oh, indeed." Lady Agnes replied calmly enough, although her conflicting emotions almost suffocated her. "Then I take it that this gypsy declares me to be a murderess."
"Oh, I shouldn"t say that exactly."
"I do say it," cried Lady Agnes, rising fiercely. "If I wrote the letter, and set the snare, I must necessarily know that some one was hiding in the shrubbery to shoot my husband. It is an abominable lie from start to finish."
"I am glad to hear you say so. But the letter?"
"The police will deal with that."
"The police? You will let Chaldea give the letter to the police?"
"I am innocent and have no fear of the police. Your attempt to blackmail me has failed, Mr. Silver."
"Be wise and take time for reflection," he urged, walking towards the door, "for I have seen this letter, and it is in your handwriting."
"I never wrote such a letter."
"Then who did--in your handwriting?"
"Perhaps you did yourself, Mr. Silver, since you are trying to blackmail me in this bareface way."
Silver snarled and gave her an ugly look. "I did no such thing," he retorted vehemently, and, as it seemed, honestly enough. "I had every reason to wish that Sir Hubert should live, since my income and my position depended upon his existence. But you--"
"What about me?" demanded Lady Agnes, taking so sudden a step forward that the little man retreated nearer the door.
"People say--"
"I know what people say and what you are about to repeat," she said in a stifled voice. "You can tell the girl to take that forged letter to the police. I am quite able to face any inquiry."
"Is Mr. Lambert also able?"
"Mr. Lambert?" Agnes felt as though she would choke.
"He was at his cottage on that night."
"I deny that; he went to London."
"Chaldea can prove that he was at his cottage, and--"
"You had better go," said Lady Agnes, turning white and looking dangerous. "Go, before you say what you may be sorry for. I shall tell Mr. Lambert the story you have told me, and let him deal with the matter."
