Matt Owens is a Pulitzer Prize–nominated journalist, but at 35, he’s adrift, more inclined to hit the bottle alone than the Miami Beach club scene. But when his beloved younger sister Mandy comes to visit, Matt wants to show her a new world. It’s the trip of her dreams, but the nightmare begins when Mandy disappears from a crowded dance floor. When her lifeless body is found, one clue --- a grisly rock song downloaded onto her iPod --- may be the calling card of a serial killer.
Shattered with grief and guilt, Matt begins a lonely journey to find Mandy’s killer, following a chain of musical clues that lead him from an abandoned London rock club to a crumbling Scottish castle and finally to the ancient bone-strewn catacombs below Paris. Only one person believes in his quest --- Eve Bellamont, a dedicated French detective whose own five-year obsession to find the phantom killer has left her an outcast in her own department. Together, they race to decipher the “killing songs” that the madman leaves with each victim and stop him before another beautiful young woman dies.
