Eleanor Tomlinson & John Hopkins

Detective Jonah Sheens is enjoying a moment of peace and quiet, when a teenage girl wanders out of the wood.

She's striking, with flame-red hair and a pale complexion.

She's also covered in blood.

She insists she's fine. It's her sister he needs to worry about.

Jonah quickly discovers that Keely and her sister, Nina, disappeared from a children's home a week ago. Now, Keely is here - but Nina's still missing.

Keely likes to play games. She knows where her sister is - but before she tells, she wants Jonah's full attention.

Is she killer, witness, or victim? And will Jonah find out what Keely's hiding, in time to save Nina?
