To the outside world, Sarah is just a normal single mum, juggling her home and work life like the other mums in her circle. She craves more though, something that will excite her. Meanwhile, DI Tom Thorne is investigating the death of a woman who, although appearing to have committed suicide, seems to be have been driven to it by a man who preys on vulnerable women. A man who Sarah is about to become acquainted with…

I have been a huge fan of Mark Billingham for many years, ever since reading Sleepy Head, the first Tom Thorne novel. Now, eighteen years later, Their Little Secret is the sixteenth Thorne book in a series that is showing no signs of losing its touch!

What we have in Their Little Secret is an incredibly clever plot. Sarah, to all intents and purposes, is a normal mum, her life revolving around her son, Jamie. There are a few little hints that she is hiding something but I was not prepared for what exactly this was! I loved the way the author developed her character to the point where I found my opinion of her at the end of the book was completely different to what I felt about her at the start!

Thorne’s experience really comes through in this book when he gets a hunch that there is more to the suicide of a woman than meets the eye. Not being able to explain what it is, and with his colleagues including Nicola Tanner less than interested, he is vindicated when the suicide case leads him to a seasoned conman and murder. Thorne is a great detective and I always feel that he comes across as a very real character. His relationship with his best pal, Phil Hendricks, is always a highlight in these books and there are certainly some great moments here.

Their Little Secret is a masterclass in how destructive relationships can be and how we don’t always know someone as well as we think we do. With several twists along the way, this was one of those books that I did not want to put down, reading it in a day. I think this may have become one of my favourite Thorne books and if this is a series you haven’t yet read, I can recommend all sixteen!
