It was perhaps nearly nine at night; he had eaten nothing since lunch, he had drunk a good deal, and he was exhausted by emotion, when the thought of Houston came into his head. He turned, not merely to the man as a friend, but to his house as a place of refuge. The danger that threatened him was still so vague, that he knew neither what to fear nor where he might expect it; but this much at least seemed undeniable, that a private house was safer than a public inn. Moved by these counsels, he turned at once to the Caledonian Station, passed (not without alarm) into the bright lights of the approach, redeemed his portmanteau from the cloak-room, and was soon whirling in a cab along the Glasgow road. The change of movement and position, the sight of the lamps twinkling to the rear, and the smell of damp and mould and rotten straw which clung about the vehicle, wrought in him strange alternations of lucidity and mortal giddiness.
"I have been drinking," he discovered; "I must go straight to bed, and sleep." And he thanked Heaven for the drowsiness that came upon his mind in waves.
From one of these spells he was awakened by the stoppage of the cab; and, getting down, found himself in quite a country road, the last lamp of the suburb shining some way below, and the high walls of a garden rising before him in the dark. The Lodge (as the place was named) stood, indeed, very solitary. To the south it adjoined another house, but standing in so large a garden as to be well out of cry; on all other sides, open fields stretched upward to the woods of Corstorphine Hill, or backward to the dells of Ravelston, or downward towards the valley of the Leith. The effect of seclusion was aided by the great height of the garden walls, which were, indeed, conventual, and, as John had tested in former days, defied the climbing schoolboy. The lamp of the cab threw a gleam upon the door and the not brilliant handle of the bell.
"Shall I ring for ye?" said the cabman, who had descended from his perch, and was slapping his chest, for the night was bitter.
"I wish you would," said John, putting his hand to his brow in one of his accesses of giddiness.
The man pulled at the handle, and the clanking of the bell replied from further in the garden; twice and thrice he did it, with sufficient intervals; in the great, frosty silence of the night the sounds fell sharp and small.
