"I am going to appeal to that officer for protection, and I don't think you will find that I shall do so in vain. You will compel people to summon the police--it is extremely unwise." The constable was sauntering towards them. Recognising, apparently, that there was logic in what Mr. Luker said, without waiting for the policeman to approach, also without going through the empty formula of wishing the solicitor good-afternoon, she marched off and left Mr. Luker alone. When she had gone, perhaps, a hundred yards, she stopped and looked back. Mr. Luker, who was still where she had left him, was seemingly enjoying a little friendly converse with the constable. She continued her progress for, possibly, another hundred yards, and then again looked back. This time Mr. Luker had vanished. She could distinguish the stalwart figure of the constable striding along in solitary state in the distance. She signalled to a hansom. "Stamford Street, Blackfriars Bridge end," was the direction she gave the driver. When the vehicle had brought her to the point she desired, descending, she dismissed it. She stood for two or three minutes, scanning the passers-by, keenly observing, so far as she was able, every one in sight. Then, turning into Stamford Street, she presently turned again into a street on her right. She was coming into a very shady neighbourhood, in which one opined that women of her appearance were very occasional visitants. She twisted and turned, however, with the unerring rapidity of one who knew it uncommonly well, until at last she found herself in what was rather an alley than a street, and a cul-de-sac at that, for at the end was nothing but a high blank wall. Here the tenements were not only extremely small, apparently consisting of five or six rooms at most, they were also of disreputable appearance. Pausing in front of one she regarded it with an attentive eye. The fact that the blinds were down gave it a deserted look. She knocked once, twice--there was no bell. When no one answered she drew a conclusion of her own. "He's not come yet; I'll wait." She did wait, for a good half-hour, with exemplary patience, in spite of the fact that long before the period of waiting was at an end she had become an object of much interest to a large number of curious eyes. Just as the observers were beginning to wonder how long she did intend to stop, the object of her flattering quest came into sight, in the shape of the legal gentleman from whom she had so lately parted--Mr. Isaac Luker. Contrary to her hopes and expectations he was not alone; once more her wily old friend had proved equal to the needs of the occasion. On either side of him were men whose character, or, rather, want of character, was written large all over them--two more unmistakable ruffians one would have to go far to see. At sight of her Mr. Luker came to a standstill.
