In Mary Higgins Clark's thirty-third novel, she goes back to the subject matter that made her first book, Where Are The Children, such a success. In Two Little Girls In Blue Clark brings to life every parent’s nightmare – the kidnap and murder of their children. Though not as nail-biting thrilling as her first foray into this topic, Clark still manages keeps things moving at a decent pace with this mystery thriller.

Steve and Margaret Frawley return to their new house after a night out in New York City to discover that their three-year-old twins, Kelly and Kathy, have been kidnapped. In a ransom note has been left, the kidnappers demand eight million dollars for the safe return of the twins. Steve and Margaret spent almost all they had to pay for their new house, so some of the executives at the corporation where he works have a pow-wow to decide whether or not to pay the ransom. Meanwhile, the three kidnappers - Lucas, Clint, and Angie (she’s Clint’s girlfriend and is taking care of the kids) - await instructions from the mysterious mastermind behind this whole scheme, the Pied Piper.

A monkey wrench is thrown into the Pied Piper’s whole plan when Steve’s corporation shells out the cash but Angie decides she wants to keep Kathy and shoots Lucas, leaving a forged suicide note claiming that Lucas accidentally killed Kathy. But Kelley makes her mother feel that Kathy is still alive through the feelings she gets, a sort of twin ESP. Soon the cynical law enforcement assigned to the case believe that Kelly just might be right as they follow clues left behind from New York to Cape Cod, building to a raise-the-hair-on-the-back-of-your-neck ending.

The only real gripe I have with this book has to do not with the plot or the concept but with the delivery. There is nothing more confusing than multiple characters in one scene talking about other characters by name within the dialogue. This is a great device to use in movies, because we can actually see the character and nothing needs to be explained. But when there are characters who have altered their identity, and their identity is revealed, and they talk about other people, it totally takes the listener out of the story. Too many characters to begin with leaves listeners not needing the added confusion. Not as good as Where Are The Children, but still a solid audio presentation.
