"I say, Mr. Narkom!" he added, raising his voice and shouting after them. "Eyes sharp to the left, all of you, when you get outside this arch. Know the neighbourhood like a book, sir. Lane forks out into a 'Y' after you get about fifty yards on. Branches off on the left where there's an old house called Gleer Cottage, sir, that hasn't been tenanted for years and years. Walled garden—tool house—stable. Great place for man to hide, sir!"

"Good boy! Thanks!" flung back Narkom. "Come on, my lads! Lively!"

Then they swung out of the arch with a rush, and the last that Lennard saw of them before the shrouding mist took them and blotted them from his view, they were pelting up the lane at top speed and making headlong for the branching "Y" to which he had directed them, their footsteps sounding on the moist surface of the road and their electric torches emitting every now and again a spark like a glowworm flashing.

Five minutes passed—the click of their flying steps had dropped off into silence; the flash of their torches had vanished in the distance and the mist; even the blurred sound of their excited voices was stilled; and neither ear nor eye could now detect anything but the soft drip of the moisture from the roof of the arch and the white oblivion of the close-pressing, ever-thickening mist.

Still he sat there, waiting—alert, watchful, keen—looking straight before him and keeping a close watch on the unobstructed end of the miniature tunnel whose entire length was still flooded with the glare from the motor's lamps. If a mouse had crawled down its damp walls he must have seen it; if even so much as a shadow had come up out of that wilderness of mist and crept into the place, he must have detected, it. But there was nothing; neither man nor beast, neither shade nor shadow; only the loneliness and the mist and the soft "plick-plick!" of the dropping moisture.

The five minutes became eight, ten, a dozen, without the slightest change in anything. Then, all of a sudden, Lennard's tense nerves gave a sort of jump and a swift prickle flashed up his spine and through his hair. A sound had come—a rustle—a step—a movement. Not from the direction in which he was looking, however, but from the lane beyond the arch and behind the limousine.

He jumped to his feet and rising on tiptoe on his driver's seat flashed the light of his electric torch back over the top of the vehicle; what he saw took all the breath out of him and set his heart and pulses hammering furiously.

Against that thick blanket of mist the penetrating power of the torch's gleam was so effectually blunted that it could do nothing more than throw a pale, weak circle of light a few feet into the depths of a crowding vapour, leaving all beyond and upon either side doubly dark in contrast.

Yet as the light streamed out and flung that circle into the impinging mist, there moved across it the figure of a woman, young and fair, with a scarf of lace thrown over her head, from beneath which fell a glory of unbound hair, thick and lustrous, over shoulders that were wrapped in ermine—ermine in mid-April!

A woman! Here! At this hour! In this time of violence and evil doing! The thing was so uncanny, so unnatural, so startlingly unexpected, that Lennard's head swam.
