The title 'sottovoce' is a musical term derived from the Italian "in a barely audible voice, a whisper" and alludes to the whispered and haunting nature of the Sottovoce's voice-over. This menacing evocation of events leading up to a terrorist attack at Oxford University is recounted from the points of view of a senior research scientist and his partner both of whom are involved in sensitive defense research and whose role in the terrorist attack remains ambiguous.
Sottovoce evokes a world where love and violence merge and contemporary political ideals fuel a new lust for human sacrifice. In its exploration of the contemporary world it unfurls a turbulent panorama of events and memories questioning an anaesthesia now commonplace.
