Steve Cavanagh was born and raised in Belfast before leaving for Dublin at the age of eighteen to study Law. He practiced civil rights law and was involved in several high-profile cases; in 2010 he represented a factory worker who suffered racial abuse in the workplace and won the largest award of damages for race discrimination in Northern Ireland legal history. He holds a certificate in Advanced Advocacy and lectures on various legal subjects (but really he just likes to tell jokes). His novel The Liar won the 2018 CWA Gold Dagger award while his follow-up novel Thirteen won the Theakston Old Peculier Crime Novel of the Year Award in 2019. Twisted and Fifty Fifty were both Sunday Times Top 10 bestsellers. He is married with two young children.
