Stained note (Dead Money)

Stained note is a paper note in the Fallout: New Vegas add-on Dead Money.

Location
It can be found on a desk in a second-floor room in the far northeast corner of Puesta del Sol North, accessible only through a broken hole in the wall above a courtyard filled with the Cloud (the Cloud may have been cleared if the Courier has reactivated Puesta del Sol's ventilation systems at the Puesta del Sol switching station already).
