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?
