Scared the absolute shit out of me, and this is doubtless one of the disadvantages of a ground-floor flat: someone just knocked on my window. Twice. Not sure what they wanted; I obviously didn’t acknowledge them. They wouldn’t have been able to see who I was, given my thick veil curtains. Hope it’s just someone who’s having problems getting home and not something more sinister…but the concierge is open 24/7 and is literally next door…
