Can you hear it?
A professor of psychoacoustics is found dead in his office. It appears to be a heart attack, until a second acoustician dies a few days later in similar circumstances.
Meanwhile, there's an outbreak of mysterious illnesses on a council estate, and outbursts of unexplained violence in a city centre nightclub. Not to mention strange noises coming from the tunnels underneath Liverpool. Can it really be coincidence that death metal band Total Depravity are back in the city, waging their own form of sonic warfare?
Detective Inspector Darren Swift is convinced there are connections. Still grieving his fiancé's death and sworn to revenge, he is thrown back into action on the trail of a murderer with a terrifying and undetectable weapon.
But this case cannot be solved using conventional detective work, and DI Swift will need to put the rulebook aside and seek the occult expertise of Dr Helen Hope and her unlikely sidekick, guitarist Mikko Kristensen.
