Danielle Faye had her car stolen and taken on a joyride around D.C. She reported it stolen but her story had inconsistencies. Consequently, was taken to the Germantown Police HQ for further questioning. Danielle's book can be found at Foggy Bottom station.
Her car, when recovered, contained the following items: two pairs of pliers, one Canadian flag, assorted theatrical costumes, four empty tequila bottles, one pool cue (broken) and four garden gnomes.
Danielle Faye is only mentioned in Fallout 3.
