These Sierra Hint books scans were contributed to the Sierra community by a reader of SierraVault, Vasyl. This collection represents a significant amount of time and investment on the part of Vasyl and he has found an excellent way to scan the books that required a "red tint" viewer to read. You'll find each page as it appeared with the obscured text followed by the same page scanned with the alternate method that makes the hidden text readable.  Whoever this guy is someone in the technical world needs to be putting him to good work.  As for us, let's just enjoy the benefits of his genius/obsessive insistence to make a scanner do something it wasn't supposed to.  Don't laugh.  We've all been there.
