In the summer of 1982, Irish aristocrat Malcolm Macarthur embarked on a brutal killing spree in a doomed plan to remedy his financial woes. Two weeks later, in a sensational turn of events, he was arrested in the home of Attorney General Patrick Connolly. The scandal attracted worldwide headlines and resulted in untold damage to then Taoiseach Charles Haughey.

The words he used to describe the dark events - grotesque, unbelievable, bizarre and unprecedented - coined the era-defining phrase GUBU. Here, award-winning political journalist Harry McGee retraces the happenings of that long hot summer and beyond. From the cat-and-mouse game to track down an unpredictable killer to Macarthur's extraordinary capture, he considers both the life and psyche of a murderer, and that of the leading political figure of the time - a man similarly driven by greed, status and a sense of himself as existing above the law.

Including previously unknown aspects of the trial and interaction with Malcolm Macarthur himself, The Murderer and the Taoiseach is a compulsive journey through tragedy and scandal.
