"I can suggest one motive. The removal of the obstacles preventing Lady Isabelle's secret marriage. Now who could have effected this? Not Lady Isabelle, she never had the audacity to carry out such a scheme; not Kingsland, he hasn't brains enough; our hostess is above suspicion; in fact there's only one person who could have conceived and carried out the plan to its successful conclusion--namely, Miss Fitzgerald." "What grounds have you for proving it?" "Was she with the parson at all, before the ceremony?" "I knew you'd ask that question!" "Then she was." "Twice, on the days just preceding--to my knowledge." "That's sufficient." "Not for me." "Then I'll tell you where we can find the missing link of evidence." "Where?" "In the marriage register of the church. Find the names of the witnesses, and you'll find the people who have carried it through. If you'll kindly leave it in my hands, I'll verify my statements to-morrow morning. I'd prefer that you did not do it yourself." "As you please. But even admitting you're right, it doesn't give the cause for the motive." "Oh, yes, it does--Miss Fitzgerald's intervention in this matter was the price of Kingsland's egging you on to propose." "Nonsense!" "I'll lay you a thousand to one on it." Stanley shrugged his shoulders, saying:-- "But your own arguments defeat you, my dear fellow. If Miss Fitzgerald was such a calculating person, why should she put herself out, and run the risk of compromising herself, merely to induce the Lieutenant to play upon my jealousy, when, as you've already shown, and I've admitted, I was so weak as to make such strategy unnecessary." "Perhaps that was not the only favour Miss Fitzgerald looked for, and the Lieutenant's hands----" "What do you mean?" "Well, taking five chests for her to London." "Oh," said the Secretary, much relieved, "I know all about that. I quite assure you it has nothing to do with Miss Fitzgerald." "But I heard her asking Kingsland to take them up for her this afternoon, and to put them in his bank." "Look here, Kent-Lauriston, your dislike for poor Belle must have got the better of your common sense. You certainly misinterpreted what she said. Those chests belong to Mr. Riddle." Kent-Lauriston changed the subject. "What is Colonel Darcy here for?" "He says, to watch his wife." "What is she here for?" "She says she has letters written to her husband by some member of this household, which have aroused her suspicions." "That sounds more promising. Who is this person?" "A woman of course--but she only knows her Christian name." "And that is?" "She will not tell me." "Ah!" said Kent-Lauriston drily. "I've sources of information about Darcy, which I'm not at liberty to give you," resumed Stanley, "but you're not on the right track, believe me."
