In the years following Hector's death, Grey became acquainted with George Everett. He introduced Grey to Lavender House, and during that time the two developed a sexual relationship. Gabaldon has confirmed that Everett was involved in the near-scandal that sent Grey to Ardsmuir in 1755, but only to the extent that "there was a near-scandal, and it involved George Everett".
They meet again when Grey returns to London after his turn as prison governor, and discuss the Hellfire Club whilst staying at Medmenham Abbey along with the club's other members. It is here that Grey reveals to Everett that he knows Everett was responsible for Robert Gerald's murder, and consequently Everett attempts to kill Grey. He comes close, but is killed by Harry Quarry before he can succeed.
