Following Pippin's trip to Harad described in "Lesser Ring," he spends one night at Budge Hall with Fredegar Bolger while on his way home.
“You shouldn’t have stayed away so long,” advised Freddy Bolger with a wave of his fork. “Your Diamond will have locked you out of the Great Smial, and will smash your own violin over your head when you show your face.”
“My wife would never lock me out of my own hole!” Pippin insisted, tipping the bottle of porter over his cup. “Isumbard and I were on our way home almost as soon as the King’s ship returned to the wharf at the Harlond. I promise you we did not monkey around in Gondor. And remember--she agreed I should stay to go with Aragorn to Harad.”
“You’d best have that in writing so as to remind her.”
Pippin laughed, “Oh, I do--the sheet of parchment, witnessed by the King himself, is in my pocket, along with a crystal pendant of the moon.”
“Aha! A bribe!”
“But of course!”
