The Madrigalator was only mentioned in the Black Book of Buried Secrets, in Amy and Dan Cahill's Agent Update. It's Dan's nickname for the black SUV that Fiske got Dan, Amy, and Nellie when they went back to Boston after the hunt. It is in this car that Nellie admits that singing isn't one of her many talents after she sings Lady Gaga's 'Bad Romance'. Amy had wanted a Prius but, Fiske had wanted the armored SUV stating, "Isabel Kabra may be locked up, but there are still people out there that who want to hurt you." Nellie drove Dan and Amy to Crestwood Cemetery where their mother and father are buried.
