Llived in a ground floor flat in S. London years ago, bedroom looked out onto a grassy verge on a quiet-ish part of the South Circular.
It was a summer evening so I had the blinds tilted open and the sash window up by about 10 inches. I decided to have an early bath, then to sit on the bed watching TV and doing my pedicure etc.
It was so hot that I ended up on the bed in my dressing gown and hair towel enjoying the breeze, and accidentally drifted off, I had the light on, so outside you could see me on the bed dozing if you got close to the window.
I woke up to the sound of the blinds clacking and thought it was the wind, realised it was late and I'd fallen asleep. Sat up to close the window only to see a hand under the blind grab the candle holder from the windowsill, and then next a shoe and bent knee edging in under the blind.
For some reason half asleep I shouted my ex's name, as if he was in the living room "D, what the fuck is all that banging, what's going on in there, come in here now".
The leg disappeared sharpish so I ran over and slammed the sash window down and locked it, ran round the flat checking the other windows, closing the blinds and chaining the door.
I waited alone for 3 hours for the police to come. They covered the windowsill with a carrier bag, and after two weeks forensics came out to dust for prints, but shockingly couldn't pick up any good ones from the sill or the candle holder.
