My hotel bedroom is on the very top floor of a 27-storey building. I therefore have the net curtains permanently drawn back so that I can enjoy the spectacular view, just drawing the main curtains at night. There is not another window in sight. No-one overlooking me.
And yet this morning, I was awoken by a knocking outside my window. Perhaps a bird had flown into it? I drew the main curtains back…to find a window-cleaner, suspended on an abseil rope, staring back at me! Was I dressed? Like the best mysteries, that is for me and the smiling window-cleaner to know.
