A famous Hollywood director arrives in Bologna to remake a cult film and the city's renown cinema archive decides to mark the occasion with a screening of the original, only to discover it has disappeared. After English detective Daniel Leicester follows the trail of Love on a Razorblade to an apparent murder-suicide, he begins to suspect there may be more at stake than missing negatives -- could the film contain a clue to one of the city's most enduring mysteries? Together with a star from the forthcoming remake, Daniel moves from the glamour of Venice Lido to the depths of Bologna's secret tunnel system as a sinister network closes in and he learns some people are ready to kill for the ultimate director's cut.
