...and when dh answered no-one was there. The only explanation I can think of is that someone was checking to see if we were in or not. The downstairs curtains were all open - we'd been out all evening - and one of our bedroom curtains was open. the knock was SO loud - we have a big brass knocker - I jumped out of my skin, ran like a quivering wreck (I was on here, dh was asleep) to rouse dh - but not a soul in sight. I really do think it was someone up to no good who;d seen the curtains and thought we might be away. dh thinks it was drunks - but there was no shouts or drunken laughs or drunken "whispers". and it was just too loud for anyone who was stumbling. what do you reckon? am I being paranoid?
