The Reticent Executioner

A female politician is shot dead in the capital. A talented detective, Kramer, is charged with leading the investigation; trouble is, he’s both much more and a great deal less than mere cop. His brilliance is at least in part due to a permanently skewed moral compass.

This is less whodunnit than whydunnit and a will-he-get-away-with it crime novel set in an England several years in the future - a world of labour camps, capital punishment, mass deportations and imprisonment without trial.
