Objection, your honor!
There IS a variant for this on page 32 in the "A to Zeds book" under 13.2. Pro Zeds Option, called "Maestro of Mystery!" (Level IV or V). It works a little different than before. (He tries to escape,you must catch him in time!)
Thank you. I just read the variant.Sounds cool although i might leave it until after 1-2 plays.
