I just realized that anyone preparing for tomorrow night by watching The Jade Mask might want to check out the front of the front door of the Harper House.
Is it a blooper that there is no front door knob on the outside of the door as I first thought?
Or . . . is Rush right (which is just as possible, darn it! ) and there is no knob on the outside of the door because Harper is paranoid and didn't want one there for security purposes?
