"She's avoiding me," Carmen said, sipping at her coffee. She was sat in Stacy's office once more, both taking their slight reprieve from the first rush of the day, though neither could afford to take long. In the last week, the flood of customers had worsened, as had their insistence that Carmen be front and centre. Stacy had said business on Carmen's off-da...

The thrum of her phone tore Carmen's gaze from her book on archaeology. Who was it this time? She checked the date; probably Leah. Opening e-mail, she was struck by another picture of Leah Adams, topless and beaming at the camera with one arm hefting up her breasts. A half empty glass of milk sat in the background.
