Bernard O'Mahoney (born 15 March 1960, Dunstable, Bedfordshire, England) is an English author, security detail, and former soldier. After taking control of security at a nightclub he became associated with Tony Tucker, a drug dealer who was shot along with two others in what is known as the Rettendon murders. O'Mahoney is also known for his affair with Michelle Taylor, a woman who was accused of (and who he now believes committed) the murder of Alison Shaughnessy. His 2001 book The Dream Solution focused on the case.
