But Mr. Wrench was not easily baffled. He telegraphed to Lord Ethalwood, begging him as a special favour to send the girl, Nell Fulford, off at once to Liverpool, with instructions for her to go to the police-station and inquire for him, Wrench.

The earl was quite as anxious as Mr. Wrench was to bring the matter to a successful issue. He deputed Mr. Jamblin to communicate with Nelly, and make known to her his wishes.

She at once expressed her willingness to go in search of the murderer of her sweetheart.

Joe Doughty, who heard of the intended expedition, begged of his master to be permitted to go also, and so, after a few hours’ notice, Nell and Joe set out together.

Upon their arrival at Liverpool they at once made their way to the police station. A constable was directed to conduct them to the house where Mr. Wrench was stopping.

“Ha’ee got any clue to the scoundrel, sir?” said Joe, when he caught sight of the detective. “I do hope un ’as.”

“Not at present,” returned Mr. Wrench. “Don’t you be too forward, my man. Just keep your tongue between your teeth. I don’t want anybody in this town to know our business, and an indiscreet word or two may spoil all. So don’t you open your mouth about the matter. Don’t say anything to a single individual. Do you understand?”

“Ah, I see, beg pardon; I won’t say a word.”

“Very well, that’s all right, my man. When I need your services, which, to say the truth, I hope I shall shortly, I’ll let you know. In the meantime keep dark, be as close as an oyster.”

Joe nodded and scratched his head. He came to the conclusion that Mr. Wrench was a wonderful man, and he was overawed by his manner, which was incisive and commanding.
