It was a noise which had been going on, very faintly, for some time; but he had thought noth-ing of it. A car passing on another road half mile away might have caused it, and a subcon-scious suggestion of the same car drawing nearer had prevented him paying much attention to the first increase in its volume. But at this moment it had swelled into a steady drone that was too powerful and unvarying for any ordinary car to make, rising to the indefinable borderline of as-sertiveness at which his sense of hearing was jolted into sitting up and taking notice. He lis-tened to it, frowning, while it grew to sharp roar --and then stopped altogether.
The Saint remained as still as the tree beside which he stood, as if he had been an integral part of it, and looked out over the hedge at the field where the light was. Rising a little oh his toes, he was able to get a clear view of it and see the cause of the light.
A double row of flares was being kindled in the field, like a file of tiny brilliant bonfires--with a sudden jerk of understanding, he remembered other days in his life, and knew what they were. Mounds of cotton waste soaked in petrol or paraffin. Even while he watched, the last of them was lighted: a reddish glow danced in the dark, licked up into a tentative flame, and spring suddenly into blazing luminance. The shadow of the man who had lit it stretched out in a sudden long bar of blackness into the surrounding gloom where the light exhausted itself. The twin rank of flares was complete, forming a broad lane of light from northwest to southeast, six flares to each side, two hundred yards long at a rough guess. The dimension of the field beyond that was lost in the darkness which lapped the light.
Over his hear there was a rush of air and a dying hiss of wind as though a monstrous bird sighed across the sky. Looking upwards, he saw a shadow like a great black cross diving against the hazy luminousness of the clouds, barely skimming the tree tops: it plunged into the lane of light, gathering shape and detail--flattened out, bumped once, and landed.
Almost at the same moment the nearer flares began to flicker and die down. One of them went out; then another. . . .
"Never again, so long as I live, will I be rude to luck," the Saint said to Patricia Holm, much later. "For every dozen minor troubles the little lady gives us, somehow or other she manages to let you draw three to a straight flush and fill your hand--once or twice in a lifetime."
He stood, fascinated, and watched the flares going out. Fifteen minutes earlier, he might have run into no end of trouble, without profit to himself or anybody else; fifteen minutes later, there might have been nothing whatever to see; only the blind gods of chance had permitted him to arrive at the exact moment when things were happening. In the outer glow of the farthest flare he saw a man attaching himself to the tail of the aeroplane and beginning to push it farther into the darkness; in a few seconds he was joined by the pilot, unidentifiable in helmet and goggles and leather coat. The engine had been switched off as the ship touched the deck, and the last scene of the drama was played out in utter silence. The two men wheeled the machine away, presumably into some invisible hangar: the last flare wavered and blinked, and the fitful gloom of the night came down once again upon the scene.
Simon Templar drew a long deep breath and stepped back out of the shadow of his tree. Of all the sins which he might have accused the top hat and spats of Sir Hugo Renway of camouflaging, ordinary smuggling was the last; but he was always accessible to new ideas.
In this case the most obvious course which presented itself was a further and yet more sleuthlike investigation into the topography and individual peculiarities of March House; and with the sublime abandon of the congenitally insane he proposed to pursue the said course without delay. The last flare was finally extinguished, and the peaceful darkness settled once more upon the field. As far as anyone outside the estate could have told, the aeroplane had flown on across the Channel-- if any reflected glow of light had been visible beyond the belt of woodland through which he had passed, and the high fence beside the road, it could hardly have attracted any ordinary citizen's attention, and it had lasted such a short time that there would have been nothing particularly remarkable about it anyway. But to anyone who had been privileged to witness the performance from the inside, the whole thing was highly furtive and irregular, especially at the country house of a justice of the peace and permanent Treasury official; and the Saint could see nothing for it but to intrude.
And it was at that psychological moment that the moon, to whose coy tactics we have already had occasion to refer, elected once again to say peekaboo to the slumbering world.
Simon Templar had owed his life to many queer things, from opening a window to dropping a cigarette, but he had never owed it before to such a rustic combination of items as a flirtatious moon and a rabbit. The rabbit appeared about one second after the moon, by lolloping out of a bush into the pool of twilight which the moon provided between two trees. The Saint had been so absolutely immobile in his observation post by the tree trunk that it could never even have noticed him: it had simply been attracted by the lighting effects provided in the adjoining field, and, being a bunny of scientific appetites and an inquisitive turn of mind, it had suspended its foraging for a space to explore this curious phenomenon. Simon saw the moving blur of it out of the corner of his eye before he realized what it was--and froze instinctively back into motionlessness almost before he had begun to move. Then he saw the rabbit clearly and moved again. A dry leaf rustled under his foot, and the rabbit twitched its nose and decided to abandon its cosmic investigations for that evening.
But it didn't lollop back into the bush from which it had emerged. Perhaps it had a date with some loose-moraled doe in the next parish and had merely paused to admire the wonders of nature on its way to more serious business or perhaps it had only heard news of some fresh young lettuces sprouting in the kitchen gardens of March House; only its reincarnation in the shape of a theosophist will ever tell. But at all events, it pushed on instead of turning back. It made a rapid hopping dive for the nearest gap in the hedge through which Simon himself had been preparing to pass.
And it died.
There was a momentary flash of blue flame, and the rabbit kicked over backwards in a dreadful leap and lay twitching in the patch of moonlight.

SlMON turned it over with his foot: it was indubitably one of the deadest rabbits in the county of Kent. Then he took a tiny flashlight from his pocket and examined the hedge with great caution. There were lines of gleaming copper wire strung through it at intervals of about six inches and rising to a height of six feet above the ground --if he had not stopped to watch the rabbit he could not have helped touching one of them.
The Saint pushed a hand somewhat unsteadily across his forehead and turned his attention to the tree. But there was no chance there of repeating his Tarzan impersonation, for there were similar copper wires coiled round the trunk to a greater height than he could reach. Without rubber gloves and insulated wire cutters he could go no farther; and he had no doubt that the same high-voltage circuit continued all the way round the landing field and enclosed everything else that might be interesting to look at.
Twenty minutes later he dropped out of another tree into the road beside his car and found Hoppy Uniatz sitting on the running board and gazing disconsolately at an inadequate hip flask which had long since run as dry as a Saharan water hole.
