Instructions to Staff is a written note found in Dishonored 2.
Transcript[]
To my privileged staff,
Today Mr. Hadros and Mrs. Vivienne will be visiting to purchase a pair of Clockwork Soldiers. My instructions are as follows:
The Arc Pylon should be stowed beneath the floor. Let's not vaporize our guests. Bring it back up only in the event of a disturbance.
Lay out refreshments, and prepare dinner for after the contracts have been signed.
If they grow restless and demand to see me, tell them I will be with them shortly, and escort them to the waiting room. Do not activate the mechanism that lowers the waiting room into the assessment chamber. I will do that once I arrive.
Location[]
The note can be found on a notice board between the main foyer and the waiting room inside the Clockwork Mansion during the mission of the same name.
