American detective Dan Elliot and his wife, Caroline, have traveled to Nice, France, to witness the wedding of their special friend, Kate Kennelly, and the wealthy Jack Boulanger. Caroline's daughter, Ruth Mannering, is serving as the maid of honor for this elegant wedding. But when Ruth and Kate don't arrive at the church for the start of the service, concern sets in. Hours later, Ruth regains consciousness on a seedy side street in Nice, and she's able to alert her parents that Kate has been kidnapped. From the moment the two women disappear, someone taunts and terrorizes the groom and his family. The culprit is called the "hyene" because of the childish song and nursery rhyme parodies that have been sent to Jack. Dan and Caroline share their unique crime-solving expertise with France's premier detective, Emile LaGrange. When kidnapping escalates to murder, Caroline does not let her disability hold her back as she, Dan, and LaGrange seek to reveal the identity of the kidnapper and murderer. Tension escalates as other deadly incidents unfold, and the detective trio must determine if this case revolves around ransom, jealousy, or revenge.

"You're telling me that Ralph Kendrick, the bogeyman of my worst nightmares has escaped from jail?" Eyes wide and unbelieving, Fiona Morgan asked the detective standing at her front door. She reached for the door frame to steady her wobbly legs. When she was ten years old, Fiona Morgan and two Girl Scout friends stumbled across Ralph Kendrick murdering a young woman at a Minneapolis park. At his trial when he was convicted of Rose Wilson's murder, Kendrick threatened to kill all three young girls if he ever got out. Now, twenty years later, Fiona discovers that Kendrick has indeed escaped from prison, and he may have wealthy connections. She hires a bodyguard, Ted Collier, veteran police officer to protect her. Matters get worse for Fiona when she finds out that Kendrick knows that she is an identical triplet. He has told other inmates he doesn't know which one testified. So he'll eliminate all of them. This means five women are at risk. Two days later, Tory Girard, one of Fiona's Girl Scout friends, is found dead in Minneapolis. Tension builds as Fiona and Ted try to stay safe and track Kendrick down before he can kill or hire someone to kill again.
