At Oxford University, fellow students remember Tom Ralis as a quiet, nerdy biology student who played percussion in the college orchestra. But even then, he had one ambition - to become a guru.

He reinvented himself as Tom Torero, a pick-up artist who approached women in the street for dates - a practice known as “daygame”. His transformation led to tragedy.

The New Gurus is a series about looking for enlightenment in the digital world.
