Is The Suspect on ITV1 based on a book?

The Suspect on ITV is indeed based on book!

The ITV thriller is based on a novel of the same name.

The Suspect is a best-selling novel by Michael Robotham.

The novel was published in 2004 and began a series about the main character – Joseph O’Loughlin – which has spanned eight more books!

The show will have a lot of content to base future series on, with some popular books in the series including Lost, Shatter and the most recent novel in the series, The Other Wife.

The Australian crime writer, Michael Robotham, has also published the successful Cyrus Haven series with one book in the series Good Girl, Bad Girl, winning the 2020 prestigious Gold Dagger award.

The novelist has also penned several stand-alone novels including When You Are Mine which was published just last year.

The Suspect episodes: Has there been an adaptation before?

A popular German adaptation of the novel, Neben der Spur, was made back in 2014.

The German TV show went on to adapt the second book in the series, Lost.

So we have good reason to hope that the ITV thriller will follow in its footsteps!
