John Christopher's award-winning Tripods Trilogy was adapted to the small screen, enthralling viewers but leaving them hanging before the end.
The BBC pulled-out two thirds of the way in leaving it forever unfinished - much to the frustration of millions of viewers worldwide - including here in NZ.
Two Tripods seasons were shown here in 1987 - on prime-time Saturday night telly.
There are fan groups around the world who have held reunions and fundraisers.
One such fan is Chris Jones, who has provided some closure with a new book The Tripods All for Nothing? - the launch of which coincided with a fundraiser for youth homelessness charity Centrepoint and an online charity auction, raising several thousand dollars.
