Would you trust a complete stranger?

After Chloe and her daughter Freya are rescued from disaster by a man, Chloe decides she must find him again to thank him. But instead of meeting her knight in shining armour, she comes across Nadine Caspian, who warns her to stay away from him. The man is dangerous, Nadine claims, and a compulsive liar. Alarmed, Chloe knows that the sensible choice would be to walk away. But she is too curious. What could Nadine have meant?
