He walked quicker and quicker, and we had some ado to keep up with him; and every now and then he left a splash of milk, silver in the lamplight.

Suddenly, almost before we could note it, he disappeared down the area steps of a house.

I believe Rupert really believed that the milkman was a fairy; for a second he seemed to accept him as having vanished.

Then calling something to me which somehow took no hold on my mind, he darted after the mystic milkman, and disappeared himself into the area.
I waited for at least five minutes, leaning against a lamp-post in the lonely street.

Then the milkman came swinging up the steps without his can and hurried off clattering down the road.
