Returns: Tuesday, April 29, at 10 pm/ET (ABC) Number of new episodes: 3

Where we left off: The Kiss-Me-Not killer set his sights on Det. Lindsay Boxer (Angie Harmon), who got protection from a hunky FBI profiler ( Stargate Atlantis' Joe Flanigan), while ADA Jill Bernhardt (Laura Harris) was ditched by her boyfriend for cheating. What's next: In an effort to save the faltering series, the network brought in veteran producer Robert Nathan ( Law & Order) to do some tweaking. "The crime stories will be more serious and relevant," Nathan vows, "so all four women will be emotionally challenged." A figure from Lindsay's past will pop up to reveal why the detective is so obsessed with her work. Love is murder: Enter a hot new beau (Joel Gretsch) for Lindsay. "We want to see her fall in love and be happy," Nathan says. Plus, Jill will choose a shocking bedmate.
