For the same reason—that Mr. Duke might get to know of it—he decided he would be wiser not to undertake the business in person. But he knew the man for the job—a certain detective-sergeant named Patrick Nolan. This man was something of a Don Juan in his way, and had a positive genius for extracting confidences from the fair sex. If he could scrape acquaintance with the maids of the establishment, it would not be long before he knew all they had to tell. Accordingly next morning he sent for Sergeant Nolan and explained his idea, and Nolan, who, where his superiors were concerned, was a man of few words, said, “Yes, sir,” and withdrew. The following day he returned with his first report. It seemed that, changing into the garb of a better-class mechanic and taking a small kit of tools with him, he had called at Mr. Duke’s in the character of an electrician who had been sent to overhaul the light fittings. Miss Duke happened to be out, and the rather pretty housemaid who opened the door, charmed with the newcomer’s manner, admitted him without hesitation. He had gone all over the house, paying particular attention to Mr. Duke’s bedroom. In the middle of the day he had asked and been granted leave to heat his can of soup at the kitchen fire, and to such purpose had he used the opportunities thus gained that before he left he had prevailed on the pretty housemaid to go with him to supper and the pictures on her next evening out. “Once I get a drop of spirits into her I’ll get all she knows,” he concluded, “though I doubt if it’ll be much.” “That’s all right so far as it goes,” French admitted, “but what have you actually found out?” “Well, there’s first of all the family. It’s a small one; there’s only the father and the daughter, Miss Sylvia. The mother’s alive, but she has been in a lunatic asylum for years, quite incurable, they said. Miss Sylvia is a nice-looking young lady and well liked, by what Rachael says—that’s the housemaid. Then there’s the servants; this Rachael, and another girl, Annie, and Sarah, the cook, and there’s a shover they call Manley. I didn’t see him, but the girls seem all right—not the kind that would be after the keys of jewel safes anyway.” “What’s the house like?” “It’s a middling big house, and the furniture’ll have been good when it was bought, though it’s getting a trifle shabby now. Mr. Duke’s bedroom is at the end of the left wing, and Miss Duke’s is in the front of the house, so anybody could go through Mr. Duke’s room without being seen. Anybody could get a mould of that key if he left it in his room, say, while he was having his bath.” “Did you find out any possibilities; any tradesmen in, like yourself, or any one staying in the house?” The Sergeant shook his head. “I did not, sir,” he admitted. “I thought I had maybe done enough for one day. I didn’t want to be after starting them wondering about me. But I’ll get that out of Rachael to-morrow night.”
