Grady

Grady's corpse can be found on the upper level of the second large room of Marigold Metro Station, near Grayditch. It appears inside a ticket booth, and is either a skeleton like in the picture, or a recently dead body with a noticeable patch of blood on the wall.

Unmarked quest: Grady's Package
Looting him yields a recording of his last words (Grady's Last Recording), asking anyone who finds his corpse to finish the job of delivering "the package" to Ronald Laren in Girdershade.

The recording describes the location of a key, in a fire hose housing (it is in a janitor's closet style room), and the location of the safe that has the package in it. When the player finds the package it turns out to be the Naughty Nightwear. You can then choose to either deliver the outfit to Ronald and receive 300 caps or you can simply choose to keep the outfit.
