This trophy has to do with the story of the DLC, but you are not guaranteed to earn it. The statue of Delilah is located on the top floor of the Timsh estate in the second mission. Sometimes the door is locked, if it is all you need to do is get the key off of Timsh. Once you enter the room, which is located to the right of Timsh’s bedroom and left of the balcony, approach the statue to your left and press to speak to it. If a guard finds you and interrupts the conversation, because you’re playing high chaos or failed to be stealthy, you will still earn the trophy; you will just miss (non-critical) story information. If you want to see where the statue is, or what the statue has to say, please refer to this video.
