David Vincent is asking himself this question many years after the show.

An old friend of David Vincent informs him that alien activity was witnessed in a city of Germany. So Vincent goes to Passau, where he faces alien beings from another planet and spies from another country.

David Vincent traveled to Langhorne, to investigate a series of mysterious deaths and a new and dangerous disease, possible brought by The Invaders.

A group of aliens who have formed a resistance movement against their own kind enlist the help of David Vincent. The group of believers face a race against time to prove alien existance before they need regenerating.

David Vincent receives a call from a mutual friend who believes the aliens are conducting their activities in Maryport, a small fishing community on the West Coast.

David Vincent discovers the aliens are using a rock group tour as a front for their plans.

Claira Morran is just a curious kid who, while on a school trip, accidently walks in to a alien landing site and stupidly gets herself noticed and in big trouble. David Vincent just happens to hear about the alien landing and visits Claira.

Snow had settled before Christmas this year and it reminded Claira of her last Christmas with her parents and she couldn't help reminding David of this fact. Also, Claira sees Father Christmas glowing red in front of her. Not to miss out on.

This is another good story that looks at David Vincent's old love before he adopted Claira. Of course love blossoms again and the Vincent's plan a wedding.

This is Part 2 and unfinished as I kind of got carried away with this but, I did like this story and I hope you will.

This is a good story with Anette now living with Steve and Sarah and the bureau have found out that a new alien outpost has been set up in the Vicent's home town. Of course, this could never be allowed to go on.

This is one of my favourite stories where an alien family has set out to capture David, Claira Steve and Sarah but the alien father is ill and dies. This is where Anette enters the stories with some good results.

This story is about Claira acquiring a boyfriend who, of course wants to know everything about what she does and why.

This is the story where Steve,the alien asks to adopt Sarah the child who asked for David and Claira's help with the aliens on her parents farm. David, in fact decides to adopt Steve in order for Steve to legally adopt Sarah. Complicated, just try writing

Now that the belivers bureau had been set up, David and Claira had been in short supply as they received a letter from a little girl living on a farm with her parents where aliens had started to arrive and use a building near to the farm.

This is the follow on story to Flashback but now with the new alien uncle and family involved.
