A Silent Death by May, Peter

A SILENT VOW
When ex-pat fugitive Jack Cleland watches his girlfriend die, gunned down in a pursuit involving officer Cristina Sanchez Pradell, he promises to exact his revenge and destroy the policewoman.

A SILENT LIFE
Cristina’s aunt Ana has been deaf and blind for the entirety of her adult life: the victim of a rare condition named Usher Syndrome. Ana is the center of Cristina’s world–and of Cleland’s cruel plan.

A SILENT DEATH
John Mackenzie–an ingenious yet irascible Glaswegian investigator–is assigned to aid the Spanish authorities in their manhunt. He alone can silence Cleland before the fugitive has the last, bloody, word.
