[King Kong]

Agreed, I don't see how parents or anyone could do that to a child. 

I didn't know about the French wording in the ransom note.  Definitely point's to the mother's writing, as OSH described above. 

I also don't think anyone breaking into a house, would take the time to write a long letter like that.  Sometimes when I'm going fishing and in a hurry to leave, it's all I can do to stop and leave Miss Kong a short note,  telling her where I'm going! And that's in my own house lol
