When bereaved mother Lizzie Becker comes to Slater and Norman for help it looks like a simple case of someone with a sick mind sending a malicious text message. Then it becomes clear the message has been sent from a mobile phone that went missing two years ago when Lizzie’s daughter, Lilly, died in a car crash.
As the detectives look into the circumstances of Lilly’s death they soon find they’re in the middle of a convoluted investigation that seems to throw up more questions than answers. At every turn, they encounter a tangled web of lies and deceit that seems designed to throw them off the scent and lead them in new directions.
Finally, despite the fog of confusion they seem to have stumbled upon the answer, but as they close in on their suspect they realise they’ve been misled yet again and the race to catch a suspect becomes a race to prevent a murder!
