 is a miscellaneous item in the Fallout: New Vegas add-on Dead Money. It can be found in Dean's Safe in the backstage of The Tampico. Using this can lead to the speech option to keep Dean Domino alive.

Bugs

 * There is a bug that prevents Dean's blackmail holotape from playing in its entirety in-game. It can only be heard properly in GECK or by use of this mod by Delamer.
