"I suppose you don't know what that means," said Crump.
"I don't," said the Angel.
"I must congratulate you. I don't know how long you will last, but you are keeping it up remarkably well. I thought at first you were a mattoid, but you're so amazingly consistent. Your attitude of entire ignorance of the elementary facts of Life is really a very amusing pose. You make slips of course, but very few. But surely we two understand one another."
He smiled at the Angel. "You would beat Sherlock Holmes. I wonder who you really are."
The Angel smiled back, with eyebrows raised and hands extended. "It's impossible for you to know who I am. Your eyes are blind, your ears deaf, your soul dark, to all that is wonderful about me. It's no good my telling that I fell into your world."
The Doctor waved his pipe. "Not that, please. I don't want to pry if you have your reasons for keeping quiet. Only I would like you to think of Hilyer's mental health. He really believes this story."
The Angel shrugged his dwindling wings.
