Naylor, now white as a ghost, sat on the edge of the bath, and stared at Dorrington as though in a fascination of terror. His hands rested on the bath at each side, and an odd sound of gurgling came from his thick throat.
"We will talk business," Dorrington resumed. "Come, you've met me before now, you know—at Redbury. You can't have forgotten Janissary, and the walking exercise and the handful of malt. I'm afraid you're a clumsy sort of rascal, Naylor, though you do your best. I'm a rascal myself (though I don't often confess it), and I assure you that your conceptions are crude as yet. Still, that isn't a bad notion in its way, that of drugging a man and drowning him in your cistern up there in the roof, when you prefer not to pay him his winnings. It has the very considerable merit that, after the body has been fished out of any river you may choose to fling it into, the stupid coroner's jury will never suspect that it was drowned in any other water but that. Just as happened in the Lawrence case, for instance. You remember that, eh? So do I, very well, and it was because I remembered that that I paid you this visit to-night. But you do the thing much too clumsily, really. When I saw a light up here in broad daylight I knew at once it must be left for some purpose to be executed later in the evening; and when I saw the steps carefully placed at the same time, after the servant had been sent out, why the thing was plain, remembering, as I did, the curious coincidence that Mr. Lawrence was drowned the very evening he had been here to take away his winnings. The steps must be intended to give access to the roof, where there was probably a tank to feed the bath, and what more secret place to drown a man than there? And what easier place, so long as the man was well drugged, and there was a strong lid to the tank? As I say, Naylor, your notion was meritorious, but your execution was wretched—perhaps because you had no notion that I was watching you."
He paused, and then went on. "Come," he said, "collect your scattered faculties, both of you. I shan't hand you over to the police for this little invention of yours; it's too useful an invention to give away to the police. I shan't hand you over, that is to say, as long as you do as I tell you. If you get mutinous, you shall hang, both of you, for the Lawrence business. I may as well tell you that I'm a bit of a scoundrel myself, by way of profession. I don't boast about it, but it's well to be frank in making arrangements of this sort. I'm going to take you into my service. I employ a few agents, and you and your tank may come in very handy from time to time. But we must set it up, with a few improvements, in another house—a house which hasn't quite such an awkward window. And we mustn't execute our little suppressions so regularly on settling-day; it looks suspicious. So as soon as you can get your faculties together we'll talk over this thing."
The man and the woman had exchanged glances during this speech, and now Naylor asked, huskily, jerking his thumb toward the man on the floor, "An'—an' what about 'im?"
"What about him? Why, get rid of him as soon as you like. Not that way, though." (He pointed toward the ceiling trap.) "It doesn't pay me, and I'm master now. Besides, what will people say when you tell the same tale at his inquest that you told at Lawrence's? No, my friend, bookmaking and murder don't assort together, profitable as the combination may seem. Settling-days are too regular. And I'm not going to be your accomplice, mind. You are going to be mine. Do what you please with Telfer. Leave him on somebody's doorstep if you like."
"But I owe him fifteen hundred, and I ain't got more than half of it! I'll be ruined!"
"Very likely," Dorrington returned placidly. "Be ruined as soon as possible, then, and devote all your time to my business. You're not to ornament the ring any longer, remember—you're to assist a private inquiry agent, you and your wife and your charming tank. Repudiate the debt if you like—it's a mere gaming transaction, and there is no legal claim—or leave him in the street and tell him he's been robbed. Please yourself as to this little roguery—you may as well, for it's the last you will do on your own account. For the future your respectable talents will be devoted to the service of Dorrington & Hicks, private inquiry agents; and if you don't give satisfaction, that eminent firm will hang you, with the assistance of the judge at the Old Bailey. So settle your business yourselves, and quickly, for I've a good many things to arrange with you."
And, Dorrington watching them continually, they took Telfer out by the side gate in the garden wall and left him in a dark corner.
Thus I learnt the history of the horrible tank that had so nearly ended my own life, as I have already related. Clearly the Naylors had changed their name to Crofting on taking compulsory service with Dorrington, and Mrs. Naylor was the repulsively thin woman who had drugged me with her coffee in the house at Highgate. The events I have just recorded took place about three years before I came to England. In the meantime how many people, whose deaths might be turned to profit, had fallen victims to the murderous cunning of Dorrington and his tools?
