He grasped his forehead, and staring on one spot of gravel, pieced together what he knew and what he suspected. Alan had murdered some one: possibly 'that man' against whom the butler chained the door in Regent Terrace; possibly another;some one at least: a human soul, whom it was death to slay and whose blood lay spilled upon the floor. This was the reason of the whisky drinking in the passage, of his unwillingness to welcome John, of his strange behaviour and bewildered words; this was why he had started at and harped upon the name of murder; this was why he had stood and hearkened, or sat and covered his eyes, in the black night.
And now he was gone, now he had basely fled; and to all his perplexities and dangers John stood heir.
'Let me think - let me think,' he said, aloud, impatiently, even pleadingly, as if to some merciless interrupter. In the turmoil of his wits, a thousand hints and hopes and threats and terrors dinning continuously in his ears, he was like one plunged in the hubbub of a crowd. How was he to remember -he, who had not a thought to spare - that he was himself the author, as well as the theatre, of so much confusion? But in hours of trial the junto of man's nature is dissolved, and anarchy succeeds.
It was plain he must stay no longer where he was, for here was a new Judicial Error in the very making. It was not so plain where he must go, for the old Judicial Error, vague as a cloud, appeared to fill the habitable world; whatever it might be, it watched for him, full-grown, in Edinburgh; it must have had its birth in San Francisco; it stood guard, no doubt, like a dragon, at the bank where he should cash his credit; and though there were doubtless many other places, who should say in which of them it was not ambushed? No, he could not tell where he was to go; he must not lose time on these insolubilities. Let him go back to the beginning. It was plain he must stay no longer where he was. It was plain, too, that he must not flee as he was, for he could not carry his portmanteau, and to flee and leave it was to plunge deeper in the mire. He must go, leave the house unguarded, find a cab, and return - return after an absence? Had he courage for that?
And just then he spied a stain about a hand's-breadth on his trouser-leg, and reached his finger down to touch it. The finger was stained red: it was blood; he stared upon it with disgust, and awe, and terror, and in the sharpness of the new sensation, fell instantly to act.
He cleansed his finger in the snow, returned into the house, drew near with hushed footsteps to the dining-room door, and shut and locked it. Then he breathed a little freer, for here at least was an oaken barrier between himself and what he feared. Next, he hastened to his room, tore off the spotted trousers which seemed in his eyes a link to bind him to the gallows, flung them in a corner, donned another pair, breathlessly crammed his night things into his portmanteau, locked it, swung it with an effort from the ground, and with a rush of relief, came forth again under the open heavens.
The portmanteau, being of occidental build, was no feather-weight; it had distressed the powerful Alan; and as for John, he was crushed under its bulk, and the sweat broke upon him thickly. Twice he must set it down to rest before he reached the gate; and when he had come so far, he must do as Alan did, and take his seat upon one corner. Here then, he sat a while and panted; but now his thoughts were sensibly lightened; now, with the trunk standing just inside the door, some part of his dissociation from the house of crime had been effected, and the cabman need not pass the garden wall.
It was wonderful how that relieved him; for the house, in his eyes, was a place to strike the most cursory beholder with suspicion, as though the very windows had cried murder.
But there was to be no remission of the strokes of fate. As he thus sat, taking breath in the shadow of the wall and hopped about by sparrows, it chanced that his eye roved to the fastening of the door; and what he saw plucked him to his feet. The thing locked with a spring; once the door was closed, the bolt shut of itself; and without a key, there was no means of entering from without.
He saw himself obliged to one of two distasteful and perilous alternatives; either to shut the door altogether and set his portmanteau out upon the wayside, a wonder to all beholders;or to leave the door ajar, so that any thievish tramp or holiday schoolboy might stray in and stumble on the grisly secret. To the last, as the least desperate, his mind inclined; but he must first insure himself that he was unobserved. He peered out, and down the long road; it lay dead empty. He went to the corner of the by-road that comes by way of Dean; there also not a passenger was stirring.
Plainly it was, now or never, the high tide of his affairs;and he drew the door as close as he durst, slipped a pebble in the chink, and made off downhill to find a cab.
Half-way down a gate opened, and a troop of Christmas children sallied forth in the most cheerful humour, followed more soberly by a smiling mother.
'And this is Christmas-day!' thought John; and could have laughed aloud in tragic bitterness of heart.
