About the Ebook

Double Proof opens with two mysteries separated by six decades — and one disgraced reporter who finds himself dragged into both.

1964: A legendary hoard of Scotch whisky — the Dalziel Double Proof — disappears without a trace.

2023: Albie Dalziel, youngest son of the wealthy whisky dynasty, vanishes. His mother hires Robbie Gould, a washed‑up journalist with a dubious reputation as a “psychic crimebuster”. Broke, desperate and out of options, Gould takes the case.

What follows is a chaotic plunge into a world of corrupt cops, drug dealers, social‑media influencers, and Japanese gangsters. When someone fires a shotgun through his front door, Gould realises he doesn’t need supernatural powers to see just how deadly things have become.

Fast, funny and full of razor‑sharp twists, Double Proof is a standout new voice in Scottish crime fiction.

“A heady mix of corrupt coppers, dodgy drug dealers and Japanese gangsters, all spiced with dark humour.”
— Sally McDonald, Sunday Post
