Provence is the stunning backdrop for this murder mystery, in which a much-anticipated vacation turns deadly and friends struggle to discover the killer in their midst. Visiting the lush lavender fields and olive groves of the French countryside is a dream come true for Darcy, Jade, Vix, and Arabelle when Darcy's Grand-mère Séraphine invites them to stay at her chateau. The women have known each other for decades and are looking forward to their reunion. But not long after their arrival Séraphine is stabbed to death. Reeling from the horrific attack, the four friends are even more unsettled when they receive a follow request from an anonymous Instagram account entitled @imwatchingyou88. The feed contains photos of the women at the chateau and includes menacing messages: "You can't hide," and "I know what you did. You won't get away with it." In the tradition of a classic Agatha Christie locked-room mystery, everyone in the chateau is a suspect, and each of the women may have a motive unknown to the other three. At least three of them have serious financial issues and could benefit if they are included in Séraphine's will. Goldis is in firm control of her plotting and stealthily employs the unreliable narrator trope with alternating first-person chapters told by Darcy, Jade, Vix, and Arabelle as well as Séraphine; the groundskeeper, Raph; and Séraphine's housekeeper, Sylvie. They all have reasons for hiding their truths, but past traumas and secrets slowly come to light. A messy extramarital affair, a missing Van Gogh painting, and a Holocaust-era betrayal spin the plot toward shocking revelations that do not stop until the very last page. Sex, lies, and secrets turn deadly in this modern-day tale built on classic plot devices. Copyright (c) Kirkus Reviews, used with permission.

Four best friends, all with secrets to hide, embark on a vacation to remember at a beautiful old château in the scenic countryside of Provence. It's been 20 years since Darcy and her friends have stayed with Darcy's grandmother Séraphine at her château. One day, Darcy, Arabelle, Jade, and Vix all unexpectedly receive invitations from Séraphine, and they each have a personal reason to accept the invitation. The vacation seems perfect with all the wineries, lavender fields, markets, and dinners--until Séraphine is found viciously murdered. While the friends try to figure out who murdered Séraphine, a mysterious Instagram account surfaces, exposing private moments from the vacation and threatening to reveal more. The old château holds many secrets, including the murderer and stalker. Can Darcy and her friends find out who the murderer is before someone else winds up dead? VERDICT While the plot in this novel from Goldis (When We Were Young) is unique, it is slow-paced and filled with clichés and unlikable characters. Avid mystery and suspense readers will be able to predict the ending, but some readers will enjoy the twists and turns.--Anna Kallemeyn
