And just then he spied a stain about a hand's breadth on his trousers-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 shot of itself; and without a key there was no means of entering from the road.

He saw himself compelled 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.
