Two disappearances. Two families. One secret. Missing persons investigator David Raker returns to crack a cold case wide open.

'Impossible to read without breaking into a sweat' The Times

'Unsettling, brilliantly plotted, and satisfyingly complex, these books are unputdownable. If you haven't yet met Raker, you're in for a treat' Mick Herron

'Grips like a vice and twists like a rollercoaster. Impossibly clever. Impossible to put down' Chris Whitaker

ONE DAY AGO...

On the night Tom Brenner and his nine-year-old son Leo visit the Seven Peaks theme park, they head straight for the ghost house.

They go in. But they don't come out.

Somewhere inside the ride, impossible as it seems, the two of them simply vanish.

FORTY YEARS AGO...

When Rebekah Murphy was three, her mother walked out of their childhood home and never returned.

Nearly four decades on, Fiona Murphy is still missing.

But then, out of the blue, a letter arrives in the post.

It says it's from Fiona.

NOW...

Missing persons investigator David Raker is hired by Rebekah to find out if the letter is actually from her mother - and soon makes a connection to the Brenners.

But these are mysteries whose secrets were never meant to be found.

And with his closest ally under arrest and about to reveal some truths of his own, the danger to Raker is coming from all sides...
