As he murmured this, his hand may be said to have resembled a sly rascal peeping round the corner, to find out things without wishing to draw observation upon himself. Mr. Sheldrake's hand sought that expressive hand, and found it in a lurking--not to say slinking--position, hiding itself demonstratively in the cuff of the policeman's coat. He slipped a piece of silver into it, and the jaws of darkness instantly devoured it up. The policeman was evidently in an unconscious state; for with the air of a man whose thoughts were far away, he received the coin obliviously, and, in an absent manner, conveyed it to the nearest pocket; then he coughed again, and assumed the air of one just aroused from a little sleep. The "open, Sesame," having been thus discreetly administered, Mr. Sheldrake learned from the policeman as much as that functionary knew concerning Lily. Yes, Lily was her real name; everybody about here knew her, and everybody liked her--children especially. She _was_ very pretty and very young: not more than nineteen, he should say. Yes, she lived on the first-floor of that house. She sang at the Royal White Rose Music-hall, you know; his missus had often heard her, and was quite in love with her. So was a good many others--not women, you know. But she was different from some other girls in that establishment who lived about here. How different? O, better, you know. Couldn't tell how long that would last; no more could any one else. He had seen a good many stage girls commence well and end badly. How badly? Well, fast, you know. It was enough to turn a girl's head; the lights, the music, the dresses, and the lots of swells with money hanging round 'em. Didn't think it would turn this one's, though. Any relatives? O, yes, she had a brother. Younger than her? No, a couple of years older, he should say; very much like her; come home late sometimes; a little fast, the young fellow was. And a mother, bedridden; the doctor often goes there. And a grandfather; a strange old fellow--a character. Immortality Wheels, people call him. Was that his proper name? O, no; nicknames both of 'em. Why Immortality? Well, he didn't quite know himself, but he'd been told it was because the old fellow was fond of talking about the immortality of the soul. Why Wheels? Well, he _did_ know that. Because the old fellow was always saying that everything in the world ought to go upon wheels. Perhaps there was something in the notion; things certainly would go easier. He _had_ heard that the old fellow had made wheels for everything in his place. Harmless old fellow; but curious notion, wasn't it? So the young fellow's a little wild, eh? Well, most young fellows are, nowadays. Very fond of each other, brother and sister are.
