Both of you / Adele Parks.

Leigh Fletcher: happily married stepmum to two gorgeous boys goes missing on Monday. Her husband Mark says he knows nothing of her whereabouts. She simply went to work and just never came home. Their family is shattered. Kai Janssen: married to wealthy Dutch businessman, Daan, vanishes the same week. Kai left their luxurious penthouse and glamorous world without a backward glance. She seemingly evaporated into thin air. Daan is distraught. DC Clements knows that people disappear all the time - far too frequently. Most run away from things, some run towards, others are taken but find their way back. A sad few never return. These two women are from very different worlds, their disappearances are unlikely to be connected. And yet, at a gut level, the DC believes they might be.
