Furneaux recognized the pungent scent of the colza oil used in policemen's lamps. "By gad," he said, "if the average criminal had the nose of the veriest cur dog he'd smell that oil a mile away. Now, where are you? There." He had butted into a constable's solid bulk. "Take me to the rock--quick. We must hide behind it, on the lower side.... Is this the place? Right! Squat down, both of you, and make yourselves comfortable, so that you won't feel your position irksome, and move perhaps at the wrong moment. When you feel me crawling away, follow to the upper foot of the rock--no farther. "Stand upright then, and try to keep your joints from cracking. There must be no creaking of belts or boots. Absolute silence is the order. Not a word spoken. No matter what you hear, don't move again until you see the light of my electric torch. Then run to me, turning on your own lamps, and help in arresting any one I may be holding. Use your handcuffs if necessary, and don't hesitate to grab hard if there is a struggle. Remember, you are to arrest _any one_, no matter who it may be. Got that?" "Yes, sir," came two eager voices. "Don't be excited. It will be an easy thing. If we make a mistake, I bear the responsibility. Now, keep still as mice when they hear a cat." One of the men giggled. Both constables had met Furneaux in the local police station that afternoon, as he had asked the Inspector to parade the pair who would be on duty during the night. It was then that he had arranged a simple code of flash signals, and warned them to look out for Winter or himself during the night. Any other person who turned up was not to be challenged until he reached the higher ground beyond the rock, but that instruction was to be acted on only in the unavoidable absence of one of the Scotland Yard officers. Privately, the constables hoped Furneaux would be their leader. They deemed him "a funny little josser," and marveled greatly at his manner and appearance. Still, they had heard of his reputation; the Inspector, in an expansive moment, had observed that "Monkey Face was sharper than he looked." Thinking example better than precept, Furneaux did not reprove the giggler. Lying there, screened even in broad daylight by the bulk of the rock and some hazels growing vigorously in that restricted area owing to the absence of foliage overhead, he listened to the voices of the night, never dumb in a large wood. Birds fluttered uneasily on the upper branches of the trees--indeed, Furneaux was lucky in that the occasional gleam of the torch had not sent a pheasant hurtling off with frantic clamor ere ever the rendezvous was reached--and some winged creature, probably an owl, swept over the rock in stealthy flight. The rabbits were all out in the open, nibbling grass and crops at leisure, but there were other tiny forms rustling among the shrubs and scampering across the soft carpet of fallen leaves.
