Suddenly I hear a horrifying shriek from out on the balcony. Harriet, my next-door neighbour, must be in distress. I hop out of the bath and rush outside to see what's wrong. She's ducked down behind a row of her washing in her lacy underwear. "What?" I say urgently, and she points over the balcony.
I look down and see about 30 members of a Jack the Ripper Tour all gazing up, their mouths gape as they spot a fresh marvel - my naked body.
I imagine them all as punters at the Heff-a-like's club and give a little shimmy and pose - but I feel a bit stupid. On stage I'm a spectacular public entertainer. On the balcony I'm nothing but a public spectacle.
