Truth is often buried where few dare to look.

A young girl disappears, echoing an unsolved murder from the past. The police think they’ve found their man, just as they had before. But they’ve already got it badly wrong once, forcing facts to fit a theory to convict an innocent man.

. Determined not to let that happen again, Detective Sergeant Anna Gwynne must go into the darkness that cloaks the worst of crimes and risk damaging herself in the process.

Can she get what she needs before another life is lost, or could the horror lead her down a path that puts her own life in grave danger?

An absolutely page-turning thriller that will have you hooked. If you love the novels of Angela Marsons and Simon McCleave, you won’t be able to put down An Unpardonable Act, Book 1 in the Anna Gwynne Black Squid trilogy.
