Sudden Moves

Katie Brashers announces to her friends that she is going to Florida for Spring Break, but when class resumes, she isn't in attendance. Classmate Michelle Martin grows suspicious, especially since she let Katie borrow a treasured book that wasn't returned. Not to mention, Katie never said goodbye to her devoted boyfriend, Brad.
Michelle confides in her best friend, Tami, and along with Brad, they form their own investigation. Dodging Michelle's demanding mother, they talk to neighbors and look inside Katie's house, posing as renters.
About to give up, Michelle takes her dog for his routine walk and uncovers a clue that leads her closer to the truth, but throws her into circumstances beyond her control.
