THIS deliciously dark and twisted crime mystery comes from a somewhat surprising source – Paul Feig, the man who brought us the likes of Bridesmaids, Spy and the Ghostbusters reboot.

Working from a multi-faceted script by Jessica Sharzer, based on the book by Darcey Bell, we follow single mum Stephanie (Anna Kendrick) who lives for helping out at her son’s school and runs a vlog where she gives domestic tips to other stay-at-home mums.

One day she meets the elegant and enigmatic Emily (Blake Lively), the mum of her son’s friend who invites Stephanie over for cocktails and the two embark on a friendship.

However, Stephanie finds herself embroiled in an unexpected mystery: just after Emily asks her for the simple favour of picking her son up from school, Emily goes missing, also leaving behind her worried husband Sean (Henry Golding).

It’s best not to know any more as this is a film that positively revels in revealing secrets, inviting you to pull on the thread of its designer outfit and watch it unravel. There’s something delightfully ominous about Feig’s venture into darker territory, a beautiful cocktail that tinges sinister mystery with humour of the most jet-black kind in its often laugh out loud dialogue.

You’re never quite sure exactly what’s going on, whether you can 100% trust whatever you’ve just witnessed and even what the characters are saying. It’s a great showcase for the two leads; Kendrick and Lively are both electrifying as they leap between the suspecting and the suspected.

It’s a supremely fun ride to unpack its Russian doll-like narrative, feeling like the act of a great magician guiding you along a lengthy trick where you think you’ve worked it out only to have the rug pulled out from underneath you.

A Hitchcockian thriller in modern Gone Girl garb, at once yearning for a stylish era of Hollywood gone by while also bringing something fresh and contemporary.
