"Eh?" cried Layard, facing round suddenly. He was in the act of driving in a brass-headed nail. The fervour in Crawford's tone caught his ear and made him suspend the blow he was about to deliver.

"Oh, nothing," said the other, with one of his short laughs. "A bad-natured joke. I meant it would be too much of a joke to think a man could be drowned in such a simple way. But this man hid himself behind the island and did not come forth at either end for half-an-hour, and I thought I'd ask you what you thought, as the circumstance piqued me. Good-night."

When he found himself in his own room he closed the window, pulled down the blind, hasped the shutters, and drew the curtains. He looked round on the simple unpretending furniture suspiciously, and muttered:

"He here--if it were he, and I think it was, appearing and disappearing in such a way! He cannot have found me out? Curse him, curse her; ay, curse her! Is not that all over now? She was to blame, too."

He walked up and down the room for an hour.

"If that was Philip Ray, where did he go to? He seems to have vanished. Layard knows every foot of this place. It was Philip Ray, and he did vanish! Could he have seen me and recognised me? or could he have tracked me, and is he now out on that little quay or wharf under my window, waiting for me? Ugh!"

CHAPTER III.

[THE PINE GROVES OF LEEHAM.]

Below London Bridge, and just at the end of the Pool, the Thames makes a sharp bend north, and keeps this course for close on a mile. Then it sweeps in a gentle curve eastward for half a mile; after this it suddenly turns south, and keeps on in a straight line for upwards of a mile. The part of London bounded on three sides by these sections of the river is not very densely populated if the acreage is considered. Much of it is taken up with the vast system of the Mercantile Docks; large spaces are wholly unbuilt on; the South London Canal, its tow-path, and double row of wharves and yards, cover a large area; and one of the most extensive gasworks in the metropolis and a convergence of railway lines take up space to the exclusion of people. There are stretches of this district as lonely by night as the top of Snowdon.

Little life stirs by day on the canal; after dark the waters and the tow-path are as deserted as a village graveyard. Along the railroad by day no human foot travels but the milesman's, and at night the traffic falls off to a mere echo of its incessant mighty roar by day. The gasworks are busy, and glowing and flaming and throbbing all through the hours of gloom and darkness, but people cannot get near them. They are enclosed by high walls on all sides except one, and on that side lies the South London Canal, which crawls and crawls unhastened and unrefreshed by the waters of any lock. The solitude of the tow-path after dark is enhanced at the point where it passes opposite the gasworks by the appearance of life across the water, and the impossibility of reaching that life, touching the human hands that labour there, receiving aid from kindly men if aid were needed. The tow-path at this point is narrow and full of fathomless shadows, in which outcasts, thieves, and murderers might lurk; deep doorways, pilasters, and ruined warehouses, where misery or crime could hide or crouch.
