[EX Q]: This book came out a long time ago. I read it when it first came out and it introduced me into the world of ghosts and and lore. I was 12 years old then in 1982 and even now when I pick it up to read....it still takes me back to the feeling...when I first picked it up and sent shivers down my spine...in a fun way of course. The stories and the drawings were perfect together. A great book. I have all 3 volumes now and I hope he comes out with a 4th one soon.Thanks Alvin and Stephen for scaring the pants off of me when I was 12.
[EX A]: Positive

[EX Q]: This machine does a decent job of cleaning when it works, but it breaks way to easily for the price, and its not built well enough to justify fixing. Too many cheap plastic parts. Consider it to be disposable if you buy it.
[EX A]: Negative

[EX Q]: Helter Skelter motive is a little far out. Real reason for murder was a copycat of Beausoeil's murder of Gary Hinman.
[EX A]:
Positive
