Not my best, but whatever.
Erik Marshall walked down the sidewalk, his head ducked down while he looked through a collection of papers. Passersby got out of the way quickly enough, but he still ran into someone every now and then. Gradually, though, the crowds started to thin out as he neared a more residential area. He looked up at the house, noting that the red roof was the same one as the picture in his files.
One deep breath later, and he was bounding up the stairs to the front entrance. He knocked on the front door, praying the girl would answer instead of her parents. The kids and teens he talked to always seemed more open without their parents around. But as luck would have it, a brunette man with glasses answered the door- no doubt her father.
"Hello, my name is Erik Marshall," he began, "I was hoping I could speak with your daughter Serena." Of course, the man managed to forget to show the elder man his badge, and instead probably looked like some perverted creep coming to talk to his daughter.
