Each lead – casinos, hidden debts and even a fugitive linked to her family – seems to crack the case, until new questions upend everything once again."No Sign of Nancy looks at the case of a woman who vanishes from her property while hosting a wedding, while Who Killed Joy is about a woman who appears to have died in a fire but is later found to have been stabbed.‌Final instalment Shot in the Dark is about a woman whose husband was shot while she was sleeping next to him.The series was a hit when it aired in the US in January, with a Decider critic saying it "does a good job of giving viewers lots of surprises".‌Fans posted messages on social media calling it "gripping", with one saying on X: "I'm freaking hooked.""I am obsessed," someone else posted on the platform, which was formerly Twitter.
