Hi Mairi, I learned a great deal about psychology, and see examples in various forums where people reject reality for alternative fanciful beliefs (fairy tales).   The story of the kidnap is riddled with stories adjusted to prove only one point, and crime analysis in real crime does not work that way.   Inthis kidnap most noticiceable is Lindbergh being allowed to call in racketeer figures, for what purpose you might ask, possibly to cover any hint of his guilt with an alternative alibi?

If you look at the photo on Ronnelle's of the Dear Sir in the nursery note you can see it is identical to the manner Anne used in her letters, but around the letter body  you can see blue residue from the letter body being completly erased?    Lindberg was clever in that after finding Anne's note he quickly erased it but left her salutation to show her he was putting her note into an envelope and sealing it for the police, as he knew this two hour ordeal waiting for the fingerprint team would wear on Anne's intent to reveal facts, by pressuring her over how guilt can be misconstrued from her letter in two hours.

Others have suggested that the writing I uncovered photographicly was some kind of lens error, double print, or digital noise, but think not, because The underwriting appears to be the same handwriting and appears to be written along similar context.   According to Berg's Book there was much unhappiness with Anne over Lindbergh, and may have been directly related to Lindbergh's ultimate prank.
