Punctual to his appointment, Kilsip called at Calton's office at eight o'clock, in order to guide him through the squalid labyrinths of the slums. He found the barrister waiting impatiently for him. The fact is, Calton had got it into his head that Rosanna Moore was at the bottom of the whole mystery, and every new piece of evidence he discovered went to confirm this belief. When Rosanna Moore was dying, she might have confessed something to Mother Guttersnipe, which would hint at the name of the murderer, and he had a strong suspicion that the old hag had received hush-money in order to keep quiet. Several times before Calton had been on the point of going to her and trying to get the secret out of her—that is, if she knew it; but now fate appeared to be playing into his hands, and a voluntary confession was much more likely to be true than one dragged piecemeal from unwilling lips.
By the time Kilsip made his appearance Calton was in a high state of excitement.
"I suppose we'd better go at once," he said to Kilsip, as he lit a cigar. "That old hag may go off at any moment."
"She might," assented Kilsip, doubtfully; "but I wouldn't be a bit surprised if she pulled through. Some of these old women have nine lives like a cat."
"Not improbable," retorted Calton, as they passed into the brilliantly-lighted street; "her nature seemed to me to be essentially feline. But tell me," he went on, "what's the matter with her—old age?"
"Partly; drink also, I think," answered Kilsip. "Besides, her surroundings are not very healthy, and her dissipated habits have pretty well settled her."
"It isn't anything catching, I hope," cried the barrister, with a shudder, as they passed into the crowd of Bourke Street.
"Don't know, sir, not being a doctor," answered the detective, stolidly.
"Oh!" ejaculated Calton, in dismay.
"It will be all right, sir," said Kilsip, reassuringly; "I've been there dozens of times, and I'm all right."
"I dare say," retorted the barrister; "but I may go there once and catch it, whatever it is."
"Take my word, sir, it's nothing worse than old age and drink."
"Has she a doctor?"
"Won't let one come near her—prescribes for herself."
"Gin, I suppose? Humph! Much more unpleasant than the usual run of medicines."
In a short time they found themselves in Little Bourke Street, and after traversing a few dark and narrow lanes—by this time they were more or less familiar to Calton—they found themselves before Mother Guttersnipe's den.
They climbed the rickety stairs, which groaned and creaked beneath their weight, and found Mother Guttersnipe lying on the bed in the corner. The elfish black-haired child was playing cards with a slatternly-looking girl at a deal table by the faint light of a tallow candle.
