In the UK, someone is reported missing every 90 seconds. Just gone. Vanished. In the blink of an eye. Picked to lead a pilot programme that has her paired with AIDE (Artificial Intelligence Detective Entity) Lock, DCS Kat Frank's instincts come up against Lock's logic. But when two missing persons' cold cases suddenly become active, Lock is the only one who can help when the case gets personal.
AI versus human experience. Logic versus instinct.
