Some murder cases you can't forget. No matter how hard you try.

The body of a woman has been found on a pristine New Zealand beach - over a decade after she was murdered.

Detective Matt Buchanan of the Auckland Police is certain it carries all the hallmarks of an unsolved crime he investigated 12 years ago: when Samantha Coates walked out one day and never came home.

Re-opening the case, Buchanan begins to piece the terrible crimes together, setting into motion a chain of events that will force him to the darkest corners of society - and back into his deepest obsession . . . 

The Sound of her Voice is a brilliantly authentic police procedural by an elite former detective - shortlisted for the 2018 Ngaio Marsh Award for Best Crime Novel.
