Name two American presidents whose children have written Washington based mysteries?

If you said Roosevelt and Truman you would have been correct.

Margaret Truman, the daughter of Harry S Truman, wrote quite a number of books about murder in and around Washington. It seems that her first mystery was even turned into the classic Wesley Snipes file Murder at 1600.

Elliott Roosevelt, one of FDR's children, wrote mysteries in which a fictionalized version of his mother serves as the 'detective.' Oh, and at least one of these is set in the White House.

And y'all thought that the children of presidents never amounted to much of anything.
