One black car parked on the curb, not running, no plates, a cracked tinted window on the passenger side with a burning cigarette sticking out, and two men inside. The neighborhood is full of families. Soccer moms and their vans, dads with their lawnmowers, and pets that get away just to pee on the neighbors' bushes. Those men in the black sedan do not belong, and the dark haired woman who spotted them right when she turned on to Willow Tree Drive knows this.
She drives by them, being as casual as she was when she left earlier that day, and turns into her driveway two houses in front of them to the right. She hums while turning off her car and grabbing her bag of groceries. There's ice cream. So she must get inside quickly.
As soon as she's in the kitchen, she puts away the groceries and grabs binoculars from out of the utility drawer. She goes into the empty living room. She never intends to furnish the house. Her stay has always been temporary. She pulls back the curtain only a little and looks through the binoculars. The men are still in the car, and another vehicle drives up and parks behind them. Same make, same model, black, tinted windows, and two more men.
The woman goes upstairs to a bedroom that has a long range rifle set up at the window. Before sitting down, she pulls back her hair into a ponytail. She takes her seat and finds her target. She breathes in and out, and with a steady aim, she squeezes the trigger, killing the driver in the first car. The expert killer doesn't waste time taking out the passenger, as well. The car behind them starts backing up screeching tires and doing a turn that rocks the car. They take off down the road. The woman stands and breaks down the weapon. It's time for her next move.
