However, disquiet sets in as Power realises he is falling under the spell of her charms and he reluctantly realises that her story may be pure fantasy.
As the mystery unfolds, Power and Lynch uncover a tangled web of deceit, which they must solve if they are to determine the truth behind the murder.
