"A fireplace?"
"And likewise a chimney, which is a chimney. When I took this place I had an eye to all the possibilities. Look here."
He went to the fireplace, a huge old-fashioned one, probably over six feet wide. The stove occupied not one-third of it. He stepped inside, I following. There was ample room for both of us. He pointed upwards.
"Stanchions, which will make excellent steps."
I saw that there were stanchions, rising one above the other, set in the side of the chimney.
"Where do they lead to?"
"Climb up twelve, put your hand out to the right, you will find a bolt. Draw it, push, a door will open. Go through it, you will find yourself upon the roof."
"The roof, at night--I thank you!"
"The chimney-stack will be on your left, between you and a fall into the street. Keep it on your left, go straight forward--you will find yourself upon the edge."
"The edge! Of the roof? Pendarvon, my thanks increase!"
