Question: man on fire is it based on a true story

Answer: Yes, Two real-life incidents shaped A.J. Quinnell's development of the book. In the first, after the eldest son of a rich Singaporean was kidnapped by Triads for ransom money, the man refused to pay the ransom, leading to the death of his son; the refusal meant that the man's other children would not become targets. The second was the kidnapping of John Paul Getty III, the son of Paul Getty, in Rome.
