This is going to be a brief review, because I have to get started on book 3 of the Glasgow Trilogy. Suffice to say that How a Gunman Says Goodbye is a worthy follow up to The Necessary Death of Lewis Winter. A fast-paced and gripping continuation of the story of Calum MacClean and the criminal underground of Glasgow. Two-thirds through, this trilogy is proving to be the perfect summertime reading choice. Strongly recommended.
