Sometimes a secret is all you have left.Detective Ngaire Blakes is back on the case when a skeletonized murder victim is discovered thirty-six years after his death. While a fierce and glorious fire lights up the Port Hills of Christchurch, Ngaire fights to piece together a crime that took place during the Springbok Tours of 1981. A period that pitted father against son, town against city, and showed the police using batons to beat back protesters on the evening news, night after night.When the victim is identified as Sam Andie, a young African American man transplanted from the States to NZ by his family, Ngaire must investigate whether racial motives were behind the death. In line with evidence from the forensic pathologist, a police baton could easily have been the murder weapon. Or was his death connected to Sam's girlfriend - a young woman convicted of a savage double homicide in the same week that Sam 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 book in a series of mystery novels set in the darkest shadows of New Zealand.
