Warning: this article contains spoilers for BBC One’s The Secrets She Keeps.

For the past few weeks, The Secrets She Keeps has been the TV show everyone’s been talking about around the (virtual) water cooler. And, earlier this week, the thriller reached its dramatic conclusion on BBC One when Meghan (Jessica De Gouw) came face-to-face with her son’s kidnapper, Aggie (Laura Carmichael).

Aggie, who emotionally revealed that she had found herself unable to conceive a baby after being forced to give up her own child as a teenager, appeared to shoot herself as police arrived on the scene.

However, viewers were left stunned when, at the end of the episode, it was revealed that Aggie had survived the self-inflicted gunshot and been sent to prison for her crimes.
