Oscar Charlie is a 13-episode CBBC children's television series that aired for the first time on 26 September 2001.
It doesn't go really well with Oscar Spinner, the father of the twelve-year-old Charlie.
Oscar appears to solve the most difficult crossword riddles with ease; and in his coat, Charlie finds a super-modern personal digital assistant.
And this way the old and young Spinner join their strengths in the fight against the international crime and espionage.
The second case (Episodes 8 to 13) appears at first glance to be about industrial espionage but it emerges that it in fact involves blackmail of the British Government by an unexpected person who kidnaps Oscar and tries to recruit him.
Oscar Spinner (David Swift) is Charlie's grandfather.
Alan Spinner (Owen Brenman) is Oscar's son and Charlie's father.
Deborah Spinner (Danielle Calvert) is Charlie's older sister.
VJ (Wahlid Choglay) is a cool, smooth and self-assured boy.
