****4 stars

As a fan of Ruth Ware, I was eager to read this advanced copy of her new book. I initially found it interesting because of the main character, Jack’s, short for Jacintha’s, profession. She’s a pen tester (penetration tester) for companies, which means she breaks into them to find weak spots in their security. She’s assisted by her husband, Gabe, a computer software coder. After a tricky night in which she’s caught entering a building and can’t reach anyone including Gabe to vouch for her, Jack is released by the police and goes home to find her husband dead with his neck slashed.

Reading the rest of the book, in which Jack searches for her husband’s killer, I was hoping for Ware’s usual twist. I felt that there was a scarcity of characters. Jack first suspects her ex-boyfriend who is a police officer. She confides in her sister and her husband’s best friend but then finds herself on the run as her alibi is seen as sketchy, and the police believe she murdered Gabe.

I didn’t find the revelation of the person responsible for Gabe’s death to be a surprise. The twist that does finally arrive at the book’s end is one I considered earlier but didn’t involve the killing and had only a minor impact on my overall impression of the story.

I would still recommend this book to Ruth Ware fans, even though I don’t feel it’s her best.
