bedroom; but beyond the fact that her name was Jane Harding, and that she had not returned to her home in Lincolnshire, the police could find no further clue. So, in brief, Jane Harding quickly joined Lady Dyke in the limbo of forgetfulness. Bruce, however, forgot nothing. Indeed, he rejoiced at this new development. "The greater the apparent mystery," he communed, "the less it is in reality. We now have two tracks to follow. They are both hidden, it is true, but when we find one, it will probably intersect the other." The new year was a few days old when Bruce made his first step through the bewildering maze which seemed to bar progress on every side. He received a report from the man, a pensioned police-officer, who had conducted a painstaking search into the history and occupation of every inhabitant of Raleigh Mansions. Two items the barrister fastened on to at once. "At No. 12, top floor right, entrance by first door on Sloane Square side, is a small flat occupied by a man named Sydney H. Corbett. He passes as an American, but is probably an Englishman who has resided in the United States. He does not mix with other Americans in London, and is of irregular habits. He frequents race meetings and sporting clubs, is reported to belong to a Piccadilly club where high play is the rule, and has no definite occupation. He occasionally visits a lady who lives at No. 61, same mansions, ground floor, and sixth door. They have been heard to quarrel seriously, and the dispute appears always to have concerned money. Corbett went to Monte Carlo early in December. His address there is 'Hotel du Cercle,' and the local post-office has a supply of stamped and addressed envelopes in which to forward his correspondence. "At No. 61, as already described, resides Mrs. Gwendoline Hillmer. She lives in good style, rents a brougham and a victoria, and is either a wealthy widow or maintained by some one of means. She dresses well, and goes out a good deal to theatres, but otherwise leads a rather lonely life. Her most frequent visitor is, or was, a gentleman who looked like an officer in the Guards, and, much less often, the aforesaid Sydney H. Corbett. Her servants, except the maid, live out. The maid, who is a sort of companion, is talkative, but does not know much, or, if she does, will not speak."
