AJ Davidson's first two books were non-fiction commissions from Gill & Macmillan. Kidnapped was a best seller and went to reprint in record time. Defamed! was a critical success, helping to direct a spotlight at Ireland's creaking libel laws.
Fiction being his first love, AJ Davidson turned to writing a series of crime mysteries, each book dealing with a different crime - murder, arson, blackmail, kidnapping etc.
His favourite motivation is to make his protagonist an unlikely hero, often a criminal. There is much more scope in giving your central character a dark side. The writer has to work that bit harder to generate empathy in the reader.
