I have been rummaging around my old tape collection and converting some into .m4b's....
Here are two fascinating books by Whitley Strieber - a popular author of fiction who then started releasing these allegedly factual accounts of his experiences of being contacted and abducted by "Visitors".
The books are given a major boost by being given a powerful read by the late great Roddy McDowall.
As I have said - these are from tape sources and tapes have been well-played over the years, so quality is a little variable but have cleaned up as much as possible.
Are the accounts real? Make up your own minds. I'll say this though - the books are compelling if nothing else.
