Looker: Laura Sims

The Professor lives in Brooklyn; her partner Nathan left her when she couldn't have a baby. All she has now is her dead-end teaching job, her ramshackle apartment, and Nathan's old moggy, Cat. Who she doesn't even like.

The Actress lives a few doors down. She's famous and beautiful, with auburn hair, perfect skin, a lovely smile. She's got children - a baby, even. And a husband who seems to adore her. She leaves her windows open, even at night.

There's no harm, the Professor thinks, in looking in through the illuminated glass at that shiny, happy family, fantasizing about them, drawing ever closer to the actress herself. Or is there?
