The assassination of the poor young husband soon passed out of notice, like other undiscovered murders. One obscure person only was foolish enough, in his leisure hours, to persist in trying to solve the problem of Who Killed Zebedee? He felt that he might rise to the highest position in the police force if he succeeded where his elders and betters had failed--and he held to his own little ambition, though everybody laughed at him. In plain English, I was the man. V. WITHOUT meaning it, I have told my story ungratefully. There were two persons who saw nothing ridiculous in my resolution to continue the investigation, single-handed. One of them was Miss Mybus; and the other was the cook, Priscilla Thurlby. Mentioning the lady first, Miss Mybus was indignant at the resigned manner in which the police accepted their defeat. She was a little bright-eyed wiry woman; and she spoke her mind freely. "This comes home to me," she said. "Just look back for a year or two. I can call to mind two cases of persons found murdered in London--and the assassins have never been traced. I am a person, too; and I ask myself if my turn is not coming next. You're a nice-looking fellow and I like your pluck and perseverance. Come here as often as you think right; and say you are my visitor, if they make any difficulty about letting you in. One thing more! I have nothing particular to do, and I am no fool. Here, in the parlors, I see everybody who comes into the house or goes out of the house. Leave me your address--I may get some information for you yet." With the best intentions, Miss Mybus found no opportunity of helping me. Of the two, Priscilla Thurlby seemed more likely to be of use. In the first place, she was sharp and active, and (not having succeeded in getting another situation as yet) was mistress of her own movements. In the second place, she was a woman I could trust. Before she left home to try domestic service in London, the parson of her native parish gave her a written testimonial, of which I append a copy. Thus it ran: "I gladly recommend Priscilla Thurlby for any respectable employment which she may be competent to undertake. Her father and mother are infirm old people, who have lately suffered a diminution of their income; and they have a younger daughter to maintain. Rather than be a burden on her parents, Priscilla goes to London to find domestic employment, and to devote her earnings to the assistance of her father and mother. This circumstance speaks for itself. I have known the family many years; and I only regret that I have no vacant place in my own household which I can offer to this good girl, (Signed) "HENRY DEERINGTON, Rector of Roth." After reading those words, I could safely ask Priscilla to help me in reopening the mysterious murder case to some good purpose.
