Elaine Blake's world has changed beyond recognition. In the last seven days, she's become a widow - possibly; travelled aboard alone for the first time; learned one of her foster children has betrayed her, and that very dangerous people will kill to get their hands on the evidence they believe she has. But all she has to go on is a nonsensical cypher, a target on her back and a large dose of paranoia and fear. Cast alone into a world of espionage, can Elaine survive? To do so she has to remember who she once was. And reveal the secrets she's kept for the last 25 years.
