The Last Goodbye: Tim Weaver

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.

Forty years ago.

When Rebekah Murphy was three, her mother walked out and never returned. Nearly four decades on, Fiona Murphy is still missing. Until a letter arrives in the post, claiming to be 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 . . .
