The car left ways that were familiar. Presently it turned into a street of long houses. The street rose steeply before, and was outlined by a long, double row of gas-lamps, stretching away to a point. It was quite silent, and the note of the car's engine sank a full tone as the ascent began.
Through the window in front, and to the left of the chauffeur, the doctor could see the lamps running past him, and suddenly he became aware of a vast blackness, darker than the houses, deeper than the sky, coming to meet him. Incredibly huge and sinister, a precipice, a mountain of stone, a nightmare castle whose grim towers were lost in night, closed the long road and barred all progress onward.
It was the North London Prison, hideous by day, frightful by night, the frontier citadel of a land of Death and gloom and shadows.
The doctor left his car and told the man to return in an hour and wait for him.
He stood before a high arched gateway. In this gateway was a door studded with sexagonal bosses of iron. Above the door was a gas-lamp. Hanging to the side of this door was an iron rod terminating in a handle of brass. This was the bell.
A sombre silence hung over everything. The roar of London seemed like a sound heard in a vision. A thin night wind sighed like a ghost in the doctor's ear as he stood before the ultimate reality of life, a reality surpassing the reality of dreams.
He stretched out his arm and pulled the bell.
The smooth and sudden noise of oiled steel bars sliding in their grooves was heard, and then a gentle "thud" as they came to rest. A small wicket door in the great ones opened. A huge sombre figure filled it and there was a little musical jingle of keys.
The visitor's voice was muffled as he spoke. In his own ears it sounded strange.
"I am Dr. Morton Sims," he said. "I have a special permit from the Home Secretary for an interview with the convict Hancock."
