I recently read a fiction book about a British person who woke up in a hotel room looking like a completely different person. He was drugged and given plastic surgery so that he would resemble a scientist that was working on a super weapon. It's a very good book but for the life of me I can't figure out what this book is or find a copy. I thought it was called "Tightrope walkers" or some variation but googling the name gives me a completely different book. Does anyone know what this book is called?
The Tightrope Men by Desmond Bagley
Giles Denison's life is turned upside down when he awakes to find himself in a luxurious hotel in Oslo and, peering into the bathroom mirror, discovers the face of another man! He has been kidnapped from his flat in London and transformed into famous Finnish scientist, Dr Harold Feltham Meyrick. Compelled to adjust to his new persona (including meeting his daughter) and to play out the role assigned to him by his captors, he embarks on a dangerous escapade from Norway to Finland and across the border into Soviet Russia.
