Barnabas, Quentin and the Body Snatchers

This is a very unusual Dark Shadows story. Basically, it's actually unique as it blends science fiction space-aliens with the normal Dark Shadows gothic realities.

It's sort of complicated to explain. There's this scientist and his daughter staying at Collinwood. The scientist is a friend of Rogers and is working on a particular space project. Seems like Apollo 13th's problem was due to a space warp of sorts. The warp had been studied and it leads to an inhabited planet. The scientist is working on a way to get humans there.

The planet doesn't like the idea of humans coming there so they sent a flying saucer with three invisible beings on board to Earth and it just happened to land near Collinwood. The aliens take take human forms (thus "body snatchers") and one becomes a duplicate of Roger and one a duplicate of the scientist.

Carolyn knows that Barnabas is a vampire, by the way. Both her and Elizabeth know that the fake Roger is really a fake Roger.

Things get more complicated when it's revealed that Marjorie is in love with a rock singer who just happens to give her a wolf's head ring and we immediately know that the singer is really Quentin.

So, we have, on one side, Elizabeth, Majorie, Carolyn, Barnabas and Quentin and, on the other side, the fake Roger, the fake scientist and a third alien. The aliens, by the way, kill a guy that Carolyn was close to so they choose that guy to establish a third fake human.

So, basically, the Collins group has the little task of freeing the real Roger and the real scientist while, at the same time, defeating the aliens and preventing an invasion of the Earth by another planet. IT all makes for a good book which actually works rather well.
