Three brothers.
One dead.
One missing.
One searching for the truth.
Thirty years ago, on the wild and unforgiving moors of Dartmoor, Alan Havers died in a tragic accident. His brothers never truly recovered-and Neal Havers never returned.
Until now.
When his brother Steven vanishes without a trace, Neal is forced back to the place he's spent a lifetime trying to forget. But Dartmoor hasn't forgotten them.
As Neal searches the windswept landscape for answers, something begins to follow him.
A presence he can't explain.
A voice that feels impossible to ignore.
A pull leading him toward a truth buried deep in the past.
Is it grief playing tricks on his mind?
Or is someone-or something-guiding him?
The answers lie hidden in a place they once knew so well... and in the secrets locked inside the Secret Letterbox.
But some truths were never meant to be uncovered.
And some bonds refuse to die.
