This is the last part of the book, in this part the Group of kids go looking in the bay for the money from the bank and they find it but the money is ruined. There was nothing new in this part but its like all of the parts that the story had came together and told them where to find 1.6 million$. So no new history just all the old history coming together.
Other parts of history in the Tacoma area is Nov 1940 - Tacoma became famous as the site of one of the world's worst engineering failures when the Tacoma Narrows suspension bridge collapsed in November 1940.
Two News Tribune employees, copy editor Leonard Coatsworth and photographer Howard Clifford, were among the last people on the bridge before it fell into the Narrows. Their first-person accounts, and Clifford's pics of the bridge collapse, are still journalism classics.
