Critics Review
‘I had a blast inside Croydon’s no-higher-stakes alt-20th-century playground. A wildly imaginative distortion of deeply researched historical fact forming a ripping tale of ‘past careens into present’ fiction. Urgent morse code message to my past self: READ THE TURING PROTOCOL NOW.’ – Trent Dalton
‘A remarkable debut novel from Nick Croydon. A smart, gripping thriller with an amazing big idea behind it. I loved it and I can’t wait for the movie and the sequel.’ – T.J. Newman
‘An incredible debut thriller where the past can be changed to save the future.’ – Don Winslow
‘A thought-provoking alternative history. The Time Machine meets The DaVinci Code.’ – Chris Hammer
‘Vivid, tense and sharp – Croydon’s concept will leave your mind and morals delightfully tangled.’ – Candice Fox
‘A fascinating alternative history with an intriguing ‘what if’ at its core. A great read.’ – Dervla McTiernan
‘The Turing Protocol is ideal for fans of The Imitation Game, The Time Traveler’s Wife, or The Man in the High Castle, and the film Oppenheimer. It’s a smart, emotionally resonant thriller that asks: what if the past could be rewritten – and what would we risk to do it? An ambitious and compelling debut. Highly recommended.’ – Megan Rogers
‘An intriguing mix of extraordinary fact and tense fiction’ * Sunday Telegraph *
‘Absorbing romp.’ * Good Reading *
