If you have read or heard about The Bible Code, here is the same rule applied to Moby Dick.

The following challenge was made by Michael Drosnin (author of The Bible Code): "When my critics find a message about the assassination of a prime minister encrypted in Moby Dick, I'll believe them."(Newsweek, Jun 9, 1997)
Note that English with the vowels included is far less flexible than Hebrew when it comes to making letters into words. Nevertheless, without further ado, we present our answer to Mr Drosnin's challenge.
