"I have absolute proof," said Lesbia quietly and rising in her turn. "Mr. Canning--The Shadow--who watched me here at my father's request, found out what I say and, if necessary, he can prove the truth of what he found out. And he will, at my request, if you do not promise to leave George alone and swear that you will not accuse him of a crime of which--as you knew all the time--he is innocent." But Maud heard only half this speech. "Canning, The Shadow," she muttered, "do you mean Captain Sargent's valet?" "Yes. I nursed him through an illness, and he has shown his gratitude to me by discovering your uncle's plot, and proving your knowledge of it. I can prove what I say with Canning's assistance, and I shall do so, unless you promise to do as I have asked you." Maud buttoned her jacket with trembling hands and moved towards the door hastily. "You are talking rubbish," she muttered in a thick voice. "I refuse to talk of the matter. It is too silly. But," she faced round, "I shall tell my uncle, and he shall have you put in gaol." "He will be in gaol himself," retorted Lesbia "As soon as you leave this house, I shall arrange with Mr. Canning to go to the police and state what he told me." "You would not dare." "Yes, I would, unless you swear not to accuse George and promise to leave him to me. I said that before: I say so again, and for the last time." "It's a----" Maud was about to say that it was a lie for the third time, but the word died away on her lips. Whether Maud was cognizant of the plot to steal the jewels Lesbia could not say, as she made no remark on this point: but her very silence showed that she was in the business. Lesbia's attitude left her no alternative but to make terms, since if she left the house, there was every danger that her uncle might be arrested. "If I do what you ask, will you hold your tongue?" Maud demanded faintly. "Then you admit that what I say is true?" countered Miss Hale. "No," almost shouted Miss Ellis, "I do not. Still, mud sticks however wrongly thrown, and I do not want my uncle to suffer through me. As to Canning, oh, my uncle will deal with him I promise you. Not a word. I agree to all you ask. I must. I shall not accuse George: I shall leave him to you and," she leaned forward with a snarl, "I shall bring misery on you at the eleventh hour." "I defy you," retorted Lesbia with scorn. "Very good." Maud smiled in an evil way. "We shall see who wins the dangerous game you are playing. I----" she broke off abruptly and left in haste. CHAPTER XIII MRS. WALKER'S VISIT
