The Arsenic Labyrinth LP (Large type / large print ed)

After ten years, Guy-a drifter with a taste for deception-has returned to Coniston in England's Lake District.

Local journalist Tony di Venuto is campaigning to revive interest in the disappearance of Emma Bestwick.

Guy knows what happened to her. He tips off Tony that Emma will not return. DCI Hannah Scarlett, head of Cumbria's Cold Case Review Team, re-opens the old investigation.

Her inquiries take her to the Museum of Myth and Legend and to the remote and eerie Arsenic Labyrinth-a series of stone tunnels used to remove arsenic from tin ore.

A shocking discovery makes it clear to Hannah that there is more than one mystery to solve.... Martin Edwards has published three Lake District Mysteries: The Coffin Trail, The Cipher Garden, and now The Arsenic Labyrinth.

He writes a regular column for Sherlock magazine and is the author of seven non-fiction books. www.martinedwardsbooks.com
