Sometimes a secret is all you have left.

Detective Ngaire Blakes is back on the case when a skeletonized murder victim is discovered—a crime that took place during the Springbok Tours of 1981. A period that pitted father against son, town against city, and police against protestors.

When the victim is identified as Sam Andie, a young African American man, Ngaire must investigate whether racial motives were behind the death. Meanwhile the forensic pathologist asserts that a police baton could easily have been the murder weapon. Or could Sam's death be connected to his girlfriend—a young woman convicted of a savage double homicide in the same week he disappeared?

With files missing, memories hazy, and a strident false confession muddying the waters, Ngaire must sift through the detritus if she hopes to find the truth hiding deep beneath the lies.

The Only Secret Left to Keep is the third mystery in a series set in the darkest shadows of New Zealand. If you enjoy puzzling mysteries, strong female leads, and the thrill of psychological suspense, then you'll enjoy the latest story in the Ngaire Blakes trilogy.
