with what he called "those half-human monsters." Mrs. Bunting, sitting there, thinking the matter of Mr. Sleuth's odd behaviour over, was glad to recall that funny incident of her long-gone youth. It seemed to prove that her new lodger was not so strange as he appeared to be. Still, when Bunting came in, she did not tell him the queer thing which had happened. She told herself that she would be quite able to manage the taking down of the pictures in the drawing-room herself.

But before getting ready their own supper, Mr. Sleuth's landlady went upstairs to clear away, and when on the staircase she heard the sound of—was it talking, in the drawing-room? Startled, she waited a moment on the landing outside the drawing-room door, then she realised that it was only the lodger reading aloud to himself. There was something very awful in the words which rose and fell on her listening ears:

"A strange woman is a narrow gate. She also lieth in wait as for a prey, and increaseth the transgressors among men."

She remained where she was, her hand on the handle of the door, and again there broke on her shrinking ears that curious, high, sing-song voice, "Her house is the way to hell, going down to the chambers of death."

It made the listener feel quite queer. But at last she summoned up courage, knocked, and walked in.

"I'd better clear away, sir, had I not?" she said. And Mr. Sleuth nodded.

Then he got up and closed the Book. "I think I'll go to bed now," he said. "I am very, very tired. I've had a long and a very weary day, Mrs. Bunting."

After he had disappeared into the back room, Mrs. Bunting climbed up on a chair and unhooked the pictures which had so offended Mr. Sleuth. Each left an unsightly mark on the wall—but that, after all, could not be helped.

Treading softly, so that Bunting should not hear her, she carried them down, two by two, and stood them behind her bed.

CHAPTER IV

Mrs. Bunting woke up the next morning feeling happier than she had felt for a very, very long time.

For just one moment she could not think why she felt so different —and then she suddenly remembered.

How comfortable it was to know that upstairs, just over her head, lay, in the well-found bed she had bought with such satisfaction at an auction held in a Baker Street house, a lodger who was paying two guineas a week! Something seemed to tell her that Mr. Sleuth would be "a permanency." In any case, it wouldn't be her fault if he wasn't. As to his—his queerness, well, there's always something funny in everybody. But after she had got up, and as the morning wore itself away, Mrs. Bunting grew a little anxious, for there came no sound at all from the new lodger's rooms. At twelve, however, the drawing-room bell rang. Mrs. Bunting hurried upstairs. She was painfully anxious to please and satisfy Mr. Sleuth. His coming had only been in the nick of time to save them from terrible disaster.

She found her lodger up, and fully dressed. He was sitting at the round table which occupied the middle of the sitting-room, and his landlady's large Bible lay open before him.

As Mrs. Bunting came in, he looked up, and she was troubled to see how tired and worn he seemed.

"You did not happen," he asked, "to have a Concordance, Mrs.
Bunting?"

She shook her head; she had no idea what a Concordance could be, but she was quite sure that she had nothing of the sort about.

And then her new lodger proceeded to tell her what it was he desired her to buy for him. She had supposed the bag he had brought with him to contain certain little necessaries of civilised life—such articles, for instance, as a comb and brush, a set of razors, a toothbrush, to say nothing of a couple of nightshirts—but no, that was evidently not so, for Mr. Sleuth required all these things to be bought now.

After having cooked him a nice breakfast Mrs. Bunting hurried out to purchase the things of which he was in urgent need.

How pleasant it was to feel that there was money in her purse again—not only someone else's money, but money she was now in the very act of earning so agreeably.

Mrs. Bunting first made her way to a little barber's shop close by. It was there she purchased the brush and comb and the razors. It was a funny, rather smelly little place, and she hurried as much as she could, the more so that the foreigner who served her insisted on telling her some of the strange, peculiar details of this Avenger murder which had taken place forty-eight hours before, and in which Bunting took such a morbid interest.

The conversation upset Mrs. Bunting. She didn't want to think of anything painful or disagreeable on such a day as this.

Then she came back and showed the lodger her various purchases. Mr.
Sleuth was pleased with everything, and thanked her most courteously.
But when she suggested doing his bedroom he frowned, and looked
quite put out.

"Please wait till this evening," he said hastily. "It is my custom to stay at home all day. I only care to walk about the streets when the lights are lit. You must bear with me, Mrs. Bunting, if I seem a little, just a little, unlike the lodgers you have been accustomed to. And I must ask you to understand that I must not be disturbed when thinking out my problems—" He broke off short, sighed, then added solemnly, "for mine are the great problems of life and death."

And Mrs. Bunting willingly fell in with his wishes. In spite of her prim manner and love of order, Mr. Sleuth's landlady was a true woman —she had, that is, an infinite patience with masculine vagaries and oddities.

When she was downstairs again, Mr. Sleuth's landlady met with a surprise; but it was quite a pleasant surprise. While she had been upstairs, talking to the lodger, Bunting's young friend, Joe Chandler, the detective, had come in, and as she walked into the sitting-room she saw that her husband was pushing half a sovereign across the table towards Joe.

Joe Chandler's fair, good-natured face was full of satisfaction: not at seeing his money again, mark you, but at the news Bunting had evidently been telling him—that news of the sudden wonderful change in their fortunes, the coming of an ideal lodger.

"Mr. Sleuth don't want me to do his bedroom till he's gone out!" she exclaimed. And then she sat down for a bit of a rest.

It was a comfort to know that the lodger was eating his good breakfast, and there was no need to think of him for the present. In a few minutes she would be going down to make her own and Bunting's dinner, and she told Joe Chandler that he might as well stop and have a bite with them.

Her heart warmed to the young man, for Mrs. Bunting was in a mood which seldom surprised her—a mood to be pleased with anything and everything. Nay, more. When Bunting began to ask Joe Chandler about the last of those awful Avenger murders, she even listened with a certain languid interest to all he had to say.

In the morning paper which Bunting had begun taking again that very day three columns were devoted to the extraordinary mystery which was now beginning to be the one topic of talk all over London, West and East, North and South. Bunting had read out little bits about it while they ate their breakfast, and in spite of herself Mrs. Bunting had felt thrilled and excited.

"They do say," observed Bunting cautiously, "They do say, Joe, that the police have a clue they won't say nothing about?" He looked expectantly at his visitor. To Bunting the fact that Chandler was
