Lucius Malfoy had sent out two letters, nearly identical in wording, dated 8th August 1991. House Crabbe had owed G11 293 to House Malfoy then; House Goyle had owed G13 885. Vincent Crabbe, Sr had been given the "choice" of paying the entire outstanding loan by 1st September 1991, or else he would pay the owed money later but his son would become Draco Malfoy’s bodyguard during the boys’ seven years at Hogwarts.
