"I am glad of that," he said. "Exceedingly glad. And yet I had suspected something of the kind. It is good for me to know that I am with friends, and that you two are only actuated by the best motives. For some days now I have had you under close observation. I followed you here to-night; indeed, I was in the house when you removed those panels. As a matter of fact, Mr. Gurdon's first involuntary visit here absolutely ruined a carefully laid plan of mine for getting Mark Fenwick into my hands. But I will tell you later on all about the mystery of the furnished dining-room and how and why the furniture vanished so strangely. When I followed you here to-night I was quite prepared to shoot you both if necessary, but some strange impulse came over me to speak to you and ask you what you were doing. I am rather glad I did, because I should not like to have a tragedy on my hands. Now would you like to come with me as far as my own rooms, where I shall be in a position to throw a little light upon a dark place or two?" Venner and Gurdon clutched eagerly at the suggestion. Without further words, they passed into the street, and would have walked down the steps had not Zary detained them. "One moment," he whispered. "Hang back in the shadow of the portico. Don't you see that there are two or three men on the steps of the house next door? Ah, I can catch the tones of that rascal Fenwick. If only that vile scoundrel knew how close to him I was at the present moment! But let us listen. Perhaps we may hear something useful." It was very still and quiet in the Square now, for the hour was late, and therefore the voices from the portico came clear and distinct to the listeners' ears. "What is the good of it?" one of the voices said. "Why on earth can't you wait till morning? Le Fenu has got clear away, and there isn't much chance of catching him again in a hurry. It was one of the coolest things I have seen for a long time." "Oh, he doesn't lack brains, or pluck either," Fenwick said. "I should have been proud of a trick like that myself. I ought to have poisoned him when I had the chance. I ought to have got him out of the way without delay. But it seemed such a safe thing to kidnap him and hide him in his own house, where we could go on with our work without the slightest danger or interruption from those accursed police. And then, when Fate played into our hands and we got hold of Evors as well, it looked as if everything was going our way. How you fools ever contrived to let him get the upper hand of you is more than I can understand."
