You never really know a man… until he’s dead.

After Terence Montez dies in a seemingly incomprehensible suicide, his family is left to sort out the emptiness he leaves behind. Terry’s wife, Isabelle, however, wants nothing more than to return to her normal life. She wants to see her daughter, Iris, back to school and lose herself in her work.

And then, they find the first letter, a love letter Terry has left behind, stashed away with no apparent intention to be found.

One letter turns into two and three and more, each one a seemingly innocuous expression of love, each one hidden away in nooks and corners around the Montez home.

Once Isabelle and Iris see patterns in the letters, they begin to suspect a disturbing intention behind them all. Each new letter fuels their suspicions, leading Isabelle and Iris across the suburbs and shopping malls of Orange County, California, where they uncover once incredible secret after another.

As the mystery slowly builds to its fiery conclusion, Isabelle discovers the horrible truth about a life she never knew and a death she could never fathom.
