The boy that never was

Five years ago, 3-year-old Dillon disappeared. For his father Harry - who left him alone for ten crucial minutes - it was an unforgivable lapse.

Yet Dillon's mother Robin has never blamed her husband: her own secret guilt is burden enough.

Now they're trying to move on, returning home to Dublin to make a fresh start.

But their lives are turned upside down the day Harry sees an 8-year-old boy in the crowd.

A boy Harry is convinced is Dillon. But the boy vanishes before he can do anything about it.

What Harry thought he saw quickly plunges their marriage into a spiral of crazed obsession and broken trust, uncovering deceits and shameful secrets.
