Allan MacKenzie Nicol was born in Buckie, but grew up in Drumchapel and Scotstoun in Glasgow. After qualifying as a Solicitor, he joined Crown Office and became a Procurator Fiscal Depute for 12 years. He qualified as an Advocate in 1993 and then defended clients charged with more serious offences until 2011, when he re-joined Crown Office and became an Advocate Depute, prosecuting in High Courts throughout Scotland.
His book Manuel: Scotland’s First Serial Killer is seen as the definitive account of Scotland’s most notorious serial killer, and was published by Black & White Publishing in 2008. Its second edition, published in 2016, coincided with the television series In Plain Sight, for which he was script adviser. His second book, The Monster Butler: Inside the Mind of a Serial Killer, was similarly published by Black & White in 2011.
Allan’s novel Liberation, the first to be published by Ringwood, came out in 2021 and is based on a real Glasgow case of a murder of a woman by a serving police officer. You can buy a copy of Liberation here.
