Another side to normal

NATHAN PALMER's last contract kill goes awry, and as he faints, the doorbell is ringing. He wakes up five days later, in southern India, with no memory of how he got there. He has contracted Typhoid and recovers with a martial arts family where he learns meditation.
Flash forward to an older version of Nathan, the assassin, who opens his door to a young lady, CLAUDIA. He is reeling from the doorbell sound that plagues him for twenty-four years. She claims to be his daughter. His shock causes a flashback to events in southern India that lead up to meeting her mother, ALINA during which time the first half of the story interchanges with a dream sequence where his dream avatar - also called Nathan - wakes up in a futuristic high-tech prison apartment.

This awful dream causes a depressed Nathan, the assassin, to continue the second half of the story as he goes on a spiritual quest of atonement with another former assassin, SAMSON, cross southern India, followed by an escape to England after another enforced kill job.
Twenty-two years later, Nathan is wiser yet still depressed, so Samson attempts to cheer him up at a masked orgy where young lady seduces him. The following experiences leads Nathan to question everything he knows...
