Trying to find a book, movie, or internet ARG (Alternate Reality Game) that uses this exact name?

Silas hands me my original car keys. I look at my reflection in the spoon. I remember my real name. But I also remember being a spy. Both memories feel equally true. I pay $1,800. I leave a five-star review on Google: "Charming flora, excellent scones, completely dismantled my ego."

And yet, when you go to open a drawer, you pause. You recall, with absolute clarity, the texture of a key that does not exist. You hear the echo of a lullaby sung by a person you never met. You feel a loyalty to a house you have already left.

The “theatre” was the converted barn behind the main house. Ten guests sat in velvet chairs. No stage. Just a single mirror on wheels. Mabel stepped in front of it and began to speak in a rhythm that wasn’t quite English.

Since your request is open-ended, I’ve drafted below. Pick the one that fits your vision, or use them as springboards.
