Brigid works for the FBI while she loves her job, she knows it's time to retire. Just when she thinks her life is taking on a new meaning, she gets a call from one of her old partners, Laura who wants Brigid to help her with a cold case. Brigid is on her way to Florida to help her mother with her dad as once again he is in the hospital.

The case that Laura wants Brigid to help her with involves Marcus Creighton. Marcus is accused of killing his wife and three children. Marcus still claims he is innocent. Brigid doesn't feel that Marcus is innocent, but Laura along with a lawyer feel that he was set up. Marcus was having an affair with Shayna. Marcus's alibi was that he was with her at the time of the murders. At first, Shayna agrees, but later during the trial, she claims she was not with him. Since Marcus had no other witnesses, everything pointed to him, and he is convicted.

Laura and Brigid are doing everything they can to try and find new evidence. But they are constantly hitting a brick wall. Alison works for a group called the Haven which deals with missing and exploited children and she has a strong interest in this case. Laura and Brigid have no idea why she would want anything to do with this case since the children were murdered. So who is really twisting the knife into Marcus? Are they going to able to save him before he is executed?

A TWIST OF THE KNIFE by Becky Masterman is fantastic. With all the twists in this book, it was hard to figure out who done it. But that is what makes a great mystery. If I can't figure it out, I know I have to keep reading. Not sure if Becky was or is an attorney but from the way she writes, I believe she is.

Becky takes you behind what a detective has to go through to find the guilty person. The more I read, the more I just couldn't put this book down. So if you like a book that you can sink your teeth in, this is the one to get. It will keep you guessing.
