Poor Frank Grimm lost both his wife and daughter and the only thing that kept him going was the need to find his daughter’s murderer. At first, he was sure it was a neighbor who had killed her so he started breaking into their homes to find a clue. Later, he broke into their homes because he liked to know what was going on in their lives since there was nothing going on in his except sorrow, grief, and guilt. I felt sorry for Frank and could understand that it was difficult for him to move on but his obsession with the neighbors, especially since he didn’t like them, was so unhealthy!

I enjoyed the other characters on Frank Grimm’s cul de sac. They were all quirky (annoying?) in their own way, and I could see why he didn’t particularly care to talk to them.

Mallory Black and her partner, Mike, were detectives who worked on the murder of Frank’s daughter. Mallory was positive that Frank was the murderer and even though he was officially cleared, she continued to investigate and was obsessed with catching him before he murdered another girl.

I did not like Mallory’s obsession with Frank because of how it affected her family. It was interesting how much alike she and Frank were, and Frank learned his lesson too late. He now realized how important dinner time should be for a family; hopefully, Mal could learn that before it was too late for her family. Even though she thought she put her family first, her job always came first. She wasn’t even concerned with her daughter’s anxiety. She just wanted to get back to work! And to her, her husband’s job had little value compared to hers.

Hidden Justice is a psychological thriller that I couldn’t put down after the first quarter of the book once Frank met his new neighbor Freya. She needed his help, and he was determined to help her no matter what. The ending was perfect. I now have a whole new series I want to read!
