In the present day, Detective Chief Inspector Alan Banks is called to the scene of a murder victim who turns out to be a freelance journalist working on a piece for MOJO magazine about the classic rock band the Mad Hatters. Since the sixties, the band has gone through a number of tragedies, losing one member to madness and another to the shallow end of a swimming pool. Putting their checkered past behind them, the Mad Hatters have now revamped their sound and are set to celebrate their forty years in the biz by embarking on their first big concert tour in years.

Banks and Detective Inspector Annie Cabbot discover that the dead journalist was onto something big hidden in the band's past, and had stirred up some very serious trouble. As Banks and Annie dig deeper into the phenomenon of the Mad Hatters, they find more than they bargained for, and soon realize that their generation's former free-love lifestyle often comes with a deadly price.

In the course of twin narratives, Robinson expertly weaves the stories of two interconnected murders that occur decades apart. As only he can, Robinson has created a novel that is as explosive as your favorite rock album and a plot that moves at breakneck speed, traversing through the tumultuous swinging sixties to present day and back again. Piece of My Heart is an extraordinary thrill ride that uncovers the gritty and violent underbelly of the generation of peace, love, and harmony.
