DON'T OIL THAT SQUEAKY DOOR.

As a constant reader of true crime books and a fan of Forensic Files, I am stunned by the number of young women who are raped or murdered by someone who climbed through their bedroom window or entered through an unlocked door. I can't imagine why a woman, especially an attractive one living alone doesn't prepare for any such an attack. Especially when it's so easy. Not only would I lock the windows, but make sure that the sills had precipitiously placed breakable items making quiet entry impossible. Same for any entrance. Place a chair or lightweight table against the door with a big cheap vase that will come crashing down at the slightest attempt at in intrusion. If your front door squeaks all the better.  You'll find more helpful hints of this kind in the book How To Be or Not To Be Murdered written and illustrated by Pat Longan.
