"A Dark Mind" is the third part of a series. I would have liked to have read the previous books so that my entry had been easier. For the histories of Lizzy, its employees and Jessica their "ward" Hayley play a big role in their actions and decisions.
Once I had found but purely and identified myself with the characters, I was entertained.
Thanks to various intermediate and flashbacks a fascinating and frightening picture of the offender will be drawn, including some surprises.
"A Dark Mind" is so exciting that I have read on a train, despite some less stereotypes.
