Detective Bob Randall, a likeable larrikin, is admired by his peers and loathed by law-breakers. His intense, ice-blue eyes have witnessed mankind's worst deeds. His affable nature hides pain and anger. It also hides his secret. The murder of both his parents when he was a young boy has skewed his sense of justice. Consequence is now a lost consideration. This trait has made him the perfect recruit for the secret organisation, DL. To secure his services, they offer him what he has always craved...revenge. A mathematical formula is all that stands between a criminal's life and death. A simple formula that determines an individual's debt to society, or DL's assessment of their worth. Fail the test and they meet Randall. He or the 'bait' he controls will be the last person they see.You will sympathise with, admire and question Randall, but in the end, it's impossible not to be engaged by his charismatic personality and unconventional ways. Written by former detective Josh Burton, who draws on his years of experience in the force in Australia, Abacus is in a genre all of its own. It is a convincing and thoroughly entertaining read.
