PRE-ORDER THE CLEVER AND INTRIGUING CRIME MYSTERY FROM THE AUTHOR OF THE TOP TEN SUNDAY TIMES BESTSELLER, THE TURNGLASS.

A new Sherlock Holmes novel, endorsed by the Conan Doyle Estate. 

Two adversaries. One deadly alliance. Together, can they unlock the truth? 

Sherlock Holmes and his faithful friend, Dr John Watson, have been hired by actor George Reynolds to help him solve a puzzle. George wants them to find out why the audience who comes to see him perform every night are the same people, only wearing disguises. Is something sinister going on and, if so, what?
 
Meanwhile, Holmes’ archenemy, Professor James Moriarty is having problems of his own. Implicated in the murder of a gang leader, Moriarty and his second, Moran, must go on the run from the police in order to find out who is behind the set-up.
 
But their investigation puts them in the way of Holmes and Watson and it’s not long before all four realise that they are being targeted by the same person. With lives on the line, not just their own, they must form an uneasy alliance in order to unmask the true villain. With clues leading them to a hotel in Switzerland and a conspiracy far greater than any of them expected, who can be trusted – and will anyone of them survive?

 
Praise for The Turnglass

'Not just a book, but an experience - one in which twists and turns are both on the page and in the very act of reading itself. Two haunting narratives conspire to create a dark, menacing tale that spans half a century of secrets as they echo back and forth' Janice Hallett

'A stunning, ingenious, truly immersive mystery. The Turnglass is a thrilling delight' Chris Whitaker 

'An intricate and thoroughly mesmerising tale of family plots and schemes across several generations' Guardian

‘Murder, mystery and secrets combine to create a dazzling achievement that will hook you in' Best

'Your initial amazement at his ingenuity comes to sit alongside an appreciation of the heart and depth he brings to his stories. A risky idea, beautifully executed' Telegraph
Industry Reviews
‘Rubin brings Sherlock back to blazing life in this intriguing new mystery’ Crime Monthly

‘Rubin gives Holmes and Moriarty an authentic feel . . . weaving enough Conan Doyle in to feel right and infusing it with an originality . . . convincing, highly entertaining and smart’ CrimeTime FM

‘If you loved Gareth’s 2023 novel The Turnglass, then make this top of your TBR pile . . . Such a pacy read, and one not just for Holmes fans but anyone who enjoys a race against time’ Belfast Telegraph

‘I was literally holding my breath towards the end of the book; I thoroughly enjoyed it’ South London Press

‘A mouth-wateringly ingenious premise’ The Telegraph
 
‘Aiming to slot seamlessly into Conan Doyle’s existing canon rather than upend it, Rubin constructs a tightly plotted, slightly fantastical mystery that is so far up the street of traditional Holmes fans it’s practically knocking down the front door of 221B’ Buzz Magazine
 
‘Entertaining and a pleasant addition to a growing post-Conan Doyle canon’ Crime Time
