Simon was the Consulting Editor of Adams from July 2015 until March 2023. Simon brought many things to the role: an encyclopaedic knowledge of the criminal law; an incisive, penetrating intellect; a gift for writing cleanly and simply; great warmth and enthusiasm; and a wonderful sense of humour. Simon continued as Consulting Editor despite failing health, with his usual punctuality. We shall miss him very much. We extend our condolences to Simon’s wife and family.
