She was gone so soon—just glimmering across the circle of light and then vanishing into the mist as suddenly as she had appeared—that for a moment or two he lost his nerve and his wits, and ducked down under the screen of the motor's top, remembering all the tales he had ever heard of ghosts and apparitions, and, in a moment of folly, half believing he had looked upon one. But of a sudden his better sense asserted itself, and realizing that for a woman—any woman, no matter how dressed, no matter how young and fair and good to look upon—to be moving stealthily about this place, at this hour, when there was talk of murder, was at least suspicious, he laid hands upon the wheel, and being unable to turn the vehicle in the arch and go after her, put on full power and went after Narkom and his men. A swift whizz carried him through the arch and up the lane, and, once in the open, he laid hand upon the bulb of the motor horn and sent blast after blast hooting through the stillness, shouting at the top of his voice as he scorched over the ground:
"Mr. Narkom! Mr. Narkom! This way, sir, this way! This way!"
CHAPTER TWO
HOW THE CHASE ENDED
Meanwhile Mr. Narkom and his zealous assistants had rushed wildly on, coming forth at last from the old railway arch into the narrow lane without so much as catching a glimpse or finding the slightest trace of either victim or murderer.
But that they had not all been deceived by an hallucination of the night, received proof from the triumphant discovery of Sergeant Petrie, who, with the aid of his torch and the bull's-eye lantern of Constable Mellish, had found the unmistakable traces of hurried footsteps on the soft, yielding earth.
"Lummy, sir! the place is alive with 'em," ejaculated Mellish. "This is the way he went, sir, down this 'ere lane, and makin' for the right of way across the fields, like wot that shuvver of yours said, sir."
Narkom, Hammond, and Petrie were at his side before he had finished speaking. It was true, other footprints were there, all the lonely tree-girt road was full of them, going down the centre in one long, unbroken line. They stopped but a moment to make sure of this, then rose and dashed on in the direction which they led.
Straight on, down the middle of the thoroughfare, without break or interruption, the foot-made trail drew them; under dripping overshadowing trees; by natural hedges and unnatural mounds where weeds and briars scrambled over piles of débris, and the light of their torches showed Narkom and his men the dim irregular outlines of a crumbling wall, green with moss and lichen and higher in parts than a man's head.
