In 1994, Robert Black was convicted of the kidnapping, sexual assault and murder of three young girls, and sentenced to life imprisonment with a minimum tariff of thirty-five years; in 2011 he was convicted of a fourth such killing. He died in HMP Maghaberry, Northern Ireland, in January 2016, aged sixty-eight, unmourned, and entirely unrepentant of his repellent crimes. These bald facts, horrific as they are, do not begin to scratch the surface of the truth about Robert Black, a Scottish-born serial killer who undoubtedly committed further murders for which he was never tried, both in this country and on the Continent. In this ground-breaking account, Robert Giles, who has spent years tracing the killer's movements and sifting through all the evidence, including transcripts of the trials, convincingly argues that Black was an habitual serial killer over many years, and quite certainly responsible for more than the four child murders for which he was convicted. Co-written with Chris Clark, a former police intelligence officer whose tireless work into the Yorkshire Ripper produced convincing new evidence of other murders that went unnoticed or unrecorded, The Face of Evil shows once and for all that Robert Black was a serial killer whose crimes went far beyond what is generally believed. In doing so, it paints a portrait of human cruelty at its worst.
