Well I have found a reference of all the apostles martyrdom:
Signature of God by Grant R. Jeffery. Unfortunately there is little in the way of references other than the Bible. Out of all the Google hits on the subject not one of 10 sites I looked at showed references except to reference Grant Scott's book. This Grant Scott must be privy to the same irrefutable information as WT. And he seems just as reluctant to share his non source evidence as well.
Amazon has his book along with The Bible Codes......any takers?
