Book Review: What She Knew by Gilly Macmillan

What She Knew by Gilly Macmillan, published December 1, 2015 by William Morrow Paperback.

Gilly Macmillan explores a mother’s search for her missing son, weaving a taut psychological thriller.

A brief summary: A divorced single mother of an eight-year-old boy becomes distraught when her son goes missing in the park during a regular Sunday walk with their dog.

 The cops follow multiple leads, just hints and threads of clues, as no one saw the boy in the woods during the walk or after he ran ahead of his mother to a rope swing in a secluded clearing just ahead of them. 
Rachel becomes a suspect in the case, while she does her best to follow leads to find her son. Who in contact with young Ben in his everyday life and would have reason to abduct him? Seems several people fit the bill. As days go by, no one is sure of the outcome. But a determined detective on the police force is sure he is on the right track. 

My thoughts:
I was immersed in the book, into the very realistic and well-drawn character of Rachel, who seemed helpless and put-upon, desperate to find Ben. Her ex-husband is not a big help, nor is his new and younger wife. 
The character of the detective is also intriguing, a man sure of his instincts in the case yet conflicted at the same time. 
The plot lagged a bit toward the middle, when it seemed as if nobody was getting anywhere in the case and no new clues cropped up. But read on.....exciting things start to happen fast. 

Themes in the book: Child abduction, family dynamics, divorce, single mothers, police procedure, the psychology behind some of those who abduct children. 

I gave this engrossing read five stars! Excellent for a debut novel.

I received an ARC of this book for my impartial review.
