Scales of Justice [EPUB ebook] 

Nobody on her college staircase seemed able to understand how Rowan came to be in the Intensive Care Ward following an overdose, nor could Rowan. She could remember nothing leading up to her admission. Over the next few weeks, as first one, and then another of her college acquaintances was murdered, Rowan began to vaguely recall some of the events, but there was always a block to fully remembering what happened on that fateful afternoon and evening.Detective Inspector Jerry Gregory and his team investigating the murders linked them to a drug dealing syndicate based around Cambridge and London, and to the back story of one of the murder victims.
