I received a free uncorrected proof of this from NetGalley in exchange for a fair review.

This is book 10 in the DI Calladine and DS Bayliss series.  This thriller involves ransomware, kidnapping, food tampering,  drug dealers, torture, and murder.  Definitely not for the faint of heart in places.  The story opens with the murder of a young man on the way home from a night out at the pub.  This gets DI Calladine involved and the case begins to move along swiftly.  The plots connect through interactions of the characters and there are also well done subplots involving their personal lives.  DI Calladine’s adult daughter is pregnant and her choice of donor has evoked rather complicated issues.  Meanwhile, Ruth’s family is coming apart at the seams.  A well done, fast paced thriller.

This is a series that vastly improved as it went on.  I had read book 2 as part of the Kindle English Mystery Book Club on Goodreads and I didn’t continue with the series at the time, but now reading this I see a substantial growth in story development and writing and would read more now.
