REVIEW:
Tammy L. Grace never fails to deliver a book that will provide me with reading pleasure. Deadly Secret is book 7 of the Cooper Harrington Detective Novels. I have enjoyed these books since I started reading them. Let me tell you why I enjoy them so much.
The first reason is the characters. I really like Coop Harrington. He is caring and a hard worker. He’s developed a lot of friends in his work that often help him out or at least send him in the correct direction. His assistant is AB. I think these two have a crush on each other but, I don’t think it has been addressed except maybe a little hint. He lives with his widowed Aunt Camille and his Dad has started to visit and stays with them also. His mother is a piece of work who is always getting into trouble and expects Coop to bail her out. She left Coop and his dad and brother years ago. It is entertaining to see what trouble she gets herself into in each book. Oh! I don’t want to forget his faithful dog, a Golden Retriever named Gus.
Coop is a private detective and has his own office in Nashville, Tennessee about 20 minutes from my home. I love that I can enjoy the feel of home while I’m reading. I enjoy seeing his world from his eyes. He is always called upon to help solve a crime or murder of some sort. I like how he and AB work together, but I can never solve the crime before they do. I am hopeless!
This book is about the granddaughter of a friend of Aunt Camille’s who moves to Washington D. C. to be an intern. She understands what her grandmother went through getting an expensive medication that she needed. Brooke Donovan wants to help fix the health care system. She is so excited to move and work on Capitol Hill. She died a short time after she started working. Police consider it a mugging gone wrong. Her parents aren’t buying it and hire Coop to go figure it out.
If you love detective stories that have a lot of heart, a murder you can’t figure out with a lot of twists and turns then Deadly Secret by Tammy L. Grace comes to you highly recommended for your reading pleasure. Until next time…Happy Reading!

SYNOPSIS:
A vanished intern. A city of secrets. A truth worth dying for.
In the busy streets near Capitol Hill, Brooke Donovan, a young intern from Nashville, meets a tragic end, her death dismissed as a random mugging. But her family smells a cover-up, and they call on Cooper Harrington, their hometown’s sharpest private eye, to unearth the truth. With his tech-savvy partner Annabelle, trusty dog Gus, and a penchant for snarky t-shirts and strong coffee, Coop dives into the capital’s shadowy elite, where a whispered secret sparks a brutal murder. Each clue drags him deeper into a web of power and lies, where one wrong move could bury the truth, and Coop, for good.
Deadly Secret, the seventh installment in Tammy L. Grace’s acclaimed Cooper Harrington Detective Novels, delivers a taut, twist-filled mystery laced with Southern grit and charm. Perfect for fans of clever sleuths, mysteries that grip until the final page, and cases that unravel with heart-pounding suspense.
Dive into the latest in the award-winning Cooper Harrington Detective Novels, featuring Coop, a Nashville lawyer turned private detective known for his love of coffee, snarky t-shirts, and talent for solving cases. He, along with his faithful dog, Gus, and his right-hand assistant, Annabelle, work together to solve murder cases full of twists and turns. You’ll find a bit of humor, a dash of southern charm, a dog who is more like a furry best friend, plenty of comfort food, and murder, of course. If you enjoy complex characters with a few quirks and plots that keep you guessing, you’ll love Tammy L. Grace’s mystery series.
The series may be read as stand-alone novels, but are more enjoyable when read in order.
