'Aflame with tension. An intricate, powerful thriller - rivals the very best of Harlan Coben and Lisa Gardner' AJ Finn, author of THE WOMAN IN THE WINDOW*****************

She was the most brutal killer of our time. And she may have been my mother...

When website columnist Robin Diamond is contacted by true crime podcast producer Quentin Garrison, she assumes it's a business matter. It's not. Quentin's podcast, Closure, focuses on a series of murders in the 1970s, committed by teen couple April Cooper and Gabriel LeRoy. It seems that Quentin has reason to believe Robin's own mother may be intimately connected with the killings.

Robin thinks Quentin's claim is absurd. But is it? The more she researches the Cooper/LeRoy murders herself, the more disturbed she becomes by what she finds. Living just a few blocks from her, Robin's beloved parents are the one absolute she's always been able to rely upon, especially now amid rising doubts about her husband and frequent threats from internet trolls. Robin knows her mother better than anyone.

But then her parents are brutally attacked, and Robin realises she doesn't know the truth at all...
