Stanley Yelnats and Hector Zerroni read the missive one last time before passing it over to a historian for analysis. It was three years since Camp Green Lake and the adventure there. Sploosh was selling and his father had moved onto a new project. His mom was able to work where she wanted, and not where she needed.
The two best friends/ next door neighbors had kept a folder of what the appraisers had said was junk from the suitcase that had given the two families a new start. Every so often one of the two boys would try and work through the file, and while they never managed to make it through the entire folder, they did make some finds.
When they did make finds, and made a little money, a third would go to the one who didn't find it, while the other two-thirds went to the discoverer. This discovery was Stanley's and it was nearly at the bottom of the folder's papers.
So here they sat, in a Houston Museum, talking to a woman who'd expressed interest in the paper that could belong to the famous female robber from a century past. She examined the paper itself before moving on.
"Well I can tell you that, the paper is authentic. So that's a plus in the right column. Now onto handwriting." She told them and turned back to her examination of the note.
45 minutes later she spoke again.
"It belongs to Katherine "Kissin' Kate" Barlow, all right. Handwriting matches. But what is truly interesting is that it answers a few questions local Historians had about our female robber. Her past was never truly known. It was speculated, but we could never confirm it. This dismisses most of the theories except for mine and a few others." She told him and Stanley sighed. It was hers, it was real. The woman started speaking again.
"If you give me a little while I might have a buyer for you to purchase this for one of the local museums." She told them and they both nodded after sharing a look. She smiled at the two of them and proceeded to preserve the missive and hand it back to them.
That night at the family dinner, the boys told the adults what happened, and everyone was relieved that it was real. Stanley and his grandfather discussed the robber and he shared the full story as told by the robber herself.
A month later the letter is displayed in the Houston Children's Museum. The museum paid a hefty price for the piece and both boys were happy with sum, and even happier with the historical answers they could get from that paper alone.
History remembered Sam Laker from that day forward.
