In top-secret talks in Barcelona, ex-spy Dr Tori Swyft seals a landmark deal over the Arctic that sends Washington DC and Moscow reeling. The next morning, she wakes beside two dead bodies …

With Spanish police converging at her door, Tori flees, in a race against time to find The Voice and prove her innocence – before it's too late.
