“That is right.” The placid voice once more resumed its sway. “Why cannot things be agreeable? I hate to have to shout, but you seem far from grasping the situation yet. Remember that I do not take the slightest risk. Also please remember, Mr Montmorency, that the action even of a hair-trigger automatic scrapes slightly as it comes up. I remind you of that for your own good, because if you are so ill-advised as to think of trying to pot me in the dark, that noise gives me a fifth of a second start of you. Do you by any chance know Zinghi’s in Mercer Street?”
“The shooting gallery?” asked Mr Montmorency a little sulkily.
“The same. If you happen to come through this alive and are interested you might ask Zinghi to show you a target of mine that he keeps. Seven shots at twenty yards, the target indicated by four watches, none of them so loud as the one you are wearing. He keeps it as a curiosity.”
“I wear no watch,” muttered Dompierre, expressing his thought aloud.
“No, Monsieur Dompierre, but you wear a heart, and that not on your sleeve,” said Carrados. “Just now it is quite as loud as Mr Montmorency’s watch. It is more central too—I shall not have to allow any margin. That is right; breathe naturally”—for the unhappy Dompierre had given a gasp of apprehension. “It does not make any difference to me, and after a time holding one’s breath becomes really painful.”
“Monsieur,” declared Dompierre earnestly, “there was no intention of submitting you to injury, I swear. This Englishman did but speak within his hat. At the most extreme you would have been but bound and gagged. Take care: killing is a dangerous game.”
“For you—not for me,” was the bland rejoinder. “If you kill me you will be hanged for it. If I kill you I shall be honourably acquitted. You can imagine the scene—the sympathetic court—the recital of your villainies—the story of my indignities. Then with stumbling feet and groping hands the helpless blind man is led forward to give evidence. Sensation! No, no, it isn’t really fair but I can kill you both with absolute certainty and Providence will be saddled with all the responsibility. Please don’t fidget with your feet, Monsieur Dompierre. I know that you aren’t moving but one is liable to make mistakes.”
“Before I die,” said Montmorency—and for some reason laughed unconvincingly in the dark—“before I die, Mr Carrados, I should really like to know what has happened to the light. That, surely, isn’t Providence?”
“Would it be ungenerous to suggest that you are trying to gain time? You ought to know what has happened. But as it may satisfy you that I have nothing to fear from delay, I don’t mind telling you. In my hand was a sharp knife—contemptible, you were satisfied, as a weapon; beneath my nose the ‘flex’ of the electric lamp. It was only necessary for me to draw the one across the other and the system was short-circuited. Every lamp on that fuse is cut off and in the distributing-box in the hall you will find a burned-out wire. You, perhaps—but Monsieur Dompierre’s experience in plating ought to have put him up to simple electricity.”
“How did you know that there is a distributing-box in the hall?” asked Dompierre, with dull resentment.
