I could see a slag heap on the hill overlooking the town—that, and a big wooden wheel hooped with metal. The latter was used to control the descent of a wooden platform down a vertical shaft. This took miners down to the coal face to begin their work. When my master had brought me here, we’d passed a line of miners heading up the hill for the night shift. They’d stopped their singing on seeing a spook and his apprentice and had even crossed to the other side to avoid us.

Tonight, though, the narrow, cobbled streets were deserted, and soon we reached the bottom of the hill, turning in to a deserted lane with broken and boarded windows. It was a place I remembered well, but the last time I’d seen it, a sign hanging by a single rusty rivet proclaimed it to be Watery Lane. Now the sign was gone.

The terraced house on the corner, the nearest to an abandoned corn merchant’s warehouse, was our destination. Its number, 13, was nailed to the door.

“This is the place,” I told Jenny as I inserted the key into the lock.

Once inside, I lit a candle and handed it to the girl. Nothing within the small living room had changed. It was empty—there was only a pile of dirty straw on the flagged floor near the window. The curtains were yellow and tattered, the whole room full of cobwebs.

Jenny put my bag down on the floor and stared about her with wide eyes.

Suddenly a chill ran down my spine—the warning that a seventh son of a seventh son receives when something from the dark is close. Soon the ghasts would be active. Would Jenny be able to see and hear them? Would she be brave enough to face those terrible entities?

I pointed to the inner door, which was partly open. “That’s the kitchen, and to the right there are stone steps leading down to the cellar.”

I remembered descending those steps, struggling to be brave, readying myself for what might be waiting in the darkness of the cellar below.

“You can tell the time by the bell you’ll hear chiming from the church tower,” I continued. “What you have to do is simple. Go down to the cellar at midnight and face what’s lurking there. Do that, Jenny, and I’ll take you on as my apprentice for at least a month. This is a test of your courage when faced with the dark. Understand?”

She nodded, but she didn’t look happy. She was shivering, all her earlier cockiness gone. It was chilly in the room, but was she trembling with cold or with fear? I couldn’t tell, but I remembered all too well the terror I’d felt at being left alone in that house. It was only natural.

Then I recalled what else the Spook had told me. I gave Jenny the same advice now.

“Don’t open the front door to anyone,” I continued. “You may hear a loud knocking, but resist the temptation to answer it. That’s one thing you mustn’t do.”
