Of course granny made an outcry the next morning, when Marie announced her intention of going again to London. All her arguments were in vain, however, and Miss Inderwick left the house early so as to catch a morning train. She promised to be back again by six o’clock, but did not tell granny where she was going—that is she admitted that the metropolis was her goal, but did not specify whither she would precisely go. Granny, believing that the wilful girl was to meet her lover, felt fairly comfortable in her mind. Had she known that Miss Inderwick purposed exploring a slum, she would have sent a telegram to Fuller to stop the excursion. Marie guessed this, so held her peace.

The girl knew exactly how to get to Rotherhithe, as she had peeped into an ABC. before leaving Belstone. On arrival at Victoria it was necessary to take the underground route, which would conduct her directly to her destination. When on the spot Marie hoped by enquiries to learn the precise whereabouts of Mother Slaig, and moreover had a faint idea that the slum the harridan lived in was called Gibson’s Rents. To explore this low neighborhood she had put on an old serge frock and a shabby black jacket, so that she was as well disguised as her uncle had been when he sought Barkers Inn. Not that Marie was ever so well dressed as Mr. Sorley, for he never gave her sufficient money to be extravagant.

The venturesome damsel duly reached Victoria Station, and had no difficulty in dropping downward to the nether railway line. Being yet a schoolgirl and feeling hungry, she bought some pastry of the jam-puff order and devoured it in the first-class compartment, which she shared with other ladies. Marie travelled in this most expensive fashion, because she thought she would be safer from being accosted by strangers. Destiny protected her in this especial way, and she gained Rotherhithe without having a single remark addressed to her. When she emerged into the open air once more, she looked helplessly around, not knowing which way to go. But she felt sure that Gibson’s Rents was the name of the slum, and asked a tall and burly policeman where it was to be found.

The officer looked at her keenly, and saw that she was a lady in spite of her shabby clothes. “Why do you wish to go there, miss?” he asked, and touched his helmet, “it’s a rough place.”

“I wish to see a woman called Mrs. Slaig.”

“Mother Slaig. Why, miss, she’s one of the worst creatures in the slum. I don’t think it is wise of you to go, miss, I don’t indeed. You’re a district visitor, I take it, miss,” went on the man, who could conceive of no other object but philanthropy which would take the young lady into such a hole, “and Mother Slaig don’t want tracts.”

Marie did not deny the identity the policeman attributed to her, as she was quick enough to see that such a character would expedite her journey, and would conceal her real intentions. She did not wish to be asked questions lest she should get into trouble, by interesting herself in a police-court case, such as the murder of Grison truly was. “I shall be all right, officer,” she answered lightly; “no one will hurt me.”

“Well, miss, I don’t think they will, for they think a heap of district visitors at Gibson’s Rents, as these ladies give them money. But I can take you to the end of my beat and pass you on to another officer, who will show you the way. Come along, miss.”

Marie conceived a high estimate of the guardians of the law, for her friend passed her along to another, who transferred her to a third, and all three men were courteous and considerate in every way. Perhaps Marie’s good looks, and engaging manners had something to do with this suavity, but she was certainly charmed with her guides. It was a fourth policeman, tall, slim and military-looking who conducted her down the crooked alley, near the riverside, where Mother Slaig had her boarding-house. There were numbers of disreputable people about, both male and female, and when the oaths of these unfortunate creatures struck her ear, and her eyes rested on their animal faces, the girl felt glad that she had a constable at her elbow. In her ignorance, she had never thought that the neighborhood was so vile as this, and half regretted coming. However, she had the high spirit of the Inderwicks, and declined to turn back, for having put her hand to the plough, the did not intend to leave it until she had driven her furrow.

The fourth policeman saw her shudder of disgust, when they stopped before a disreputable house, dingy, tumble-down, and dilapidated. “I shall stay here while you give Mother Slaig your tracts, miss,” he said politely, also taking her for a district visitor, “and if anything goes wrong, you just call for me.”
