D.I.E.

or Death Investigation Extension (Traditional Chinese: 古靈精探) is a TVB modern comedy-action series broadcast in March 2008.

Yue Chi-Long (Roger Kwok), who has cracked a large number of difficult cases by extrasensory means, is assigned to the D.I.E.

New appointee Ying Jing-Jing (Sonija Kwok) is a good-looking girl but she takes an uncompromising stand over every case she deals with.

Initially unaccepting of a division made of incompetent detectives, she is tricked into staying by her former supervisor, who claims that she was placed there to eventually replace the head and whip the team into shape.

While Chi-Ching is accepting, Chi-Long is angry at his father, going as far as arresting him when evidence hinted that Tai-Hoi may be related to a murder.

The original ending of the series has Roger Kwok's character, Yue Sir, dead as a result of the car accident.
