I went out into the street again, and the cabmen flung up their aprons, inviting my patronage. I picked out a cab and got in.

“Where to?”

“Just stay where you are. I'm hiring you by the hour.”

The cabmen walk about whispering, one suggesting this, another that: he's watching the place; out to catch his wife meeting some commercial traveller.

Yes, I am watching the place. There is a light in one or two of the rooms, and suddenly it strikes me that she might stand at a window and see me. “Wait,” I say to the cabman, and go into the hotel again.

“Whereabouts is No. 12?”

“First floor.”

“Looking out on to Raadhusgaten?”

“Yes.”

“Then it must have been my sister,” I say, inventing something in order to slip past the porter.
