Detective Josie Quinn #23
The Couple's Secret by Lisa Regan is a very highly recommended mystery/procedural. This is the 23rd novel in the Detective Josie Quinn series but it can be read as a stand-alone novel. In fact, after reading it you will want to read more in this series.
A call comes in alerting the Denton Police department that a car has been spotted in the river at a remote area. Detective Josie Quinn and her partner Gretchen go out to investigate and Josie determines the car has been there for several years. It is revealed that inside the car are the skeletal remains of Tobias Lachlan and his fiancée Cora Stevens, a couple who disappeared seven years earlier.
The medical examiner reveals that the couple were both murdered which means the car was pushed into the river and the missing persons case is now a murder investigation. Tobias and Cora’s children, Jackson, Zane and Riley, are now adults and Josie is determined to find who murdered their parents because someone always knows something.
The writing is excellent, the pace is lightning-fast, and the tension rises with each chapter as all the clues are all logically followed up on in this compelling murder mystery. There are some obvious suspects, but, as the investigation unfolds, secrets are uncovered and seem to multiply. There are several twists in the plot as new information is uncovered and changes the direction of inquiries.
In Josie's personal life, Noah, who also works for the police department, is still recovery from the aftermath of a previous case. The two are now custodial parents to Wren, a teenager who is still grieving from her parents deaths. All the backstory and history of the characters is covered enough that new readers can follow along and appreciate this latest addition to the series. I really enjoyed all the realistic interaction between characters which helps bring them all to life as fully realized individuals.
The Couple's Secret is a natural choice for anyone following
the series, but new readers can jump into it this time and enjoy the
excellent mystery/procedural. Thanks to Bookouture for providing me with an
advance reader's copy via NetGalley. My review is voluntary and
