Sarah began to worry when her eight-year-old daughter, Harper, started coming home later than usual after ballet lessons. When Sarah and her husband, David, decided to follow Harper to see what was causing the delay, they were shocked by what they discovered.Sarah anxiously watched the clock, concerned that Harper’s ballet class had ended nearly an hour ago and she still wasn’t home. She tried to reassure herself that perhaps Lena’s mom, who was responsible for picking up the girls that day, had an errand to run. When Harper finally walked through the door, Sarah immediately asked why she was late. Harper’s reply was subdued; she claimed she stayed back to practice a new routine with her friends. Sarah’s unease grew, especially since Harper had been late every day that week. When Sarah questioned her further, Harper avoided eye contact and quickly changed the subject.
