The master of knots - Massimo Carlotto

Alligator - former blues singer, ex-convict, now a private detective - finds himself pulled into a dark and unsettling case that uncovers an Italy known to very few.

When Helena Giraldi is abducted, her husband approaches Alligator and his friends for help. Helena and Mariano lead a secret double life involving Italy's clandestine S&M scene. But Mariano seems more worried about losing his job and reputation than about seeing his wife again.

As Alligator begins to investigate, he uncovers a secretive and dangerous world in which brutality, duplicity and passion go hand in hand. Behind Helena's abduction is a shadowy figure known as The Master of Knots - who proves to be as powerful as he is psychotic. As more members of the underground scene start to disappear, Alligator finds himself in a desperate race against time to reveal the true identity of The Master of Knots. The search leads him into a world where truth is an elusive concept, where no one is who they seem to be - and where the line between pleasure and pain simply doesn't exist.
