OPEN [space] DOOR

Jessica Fletcher (Angela Lansbury) has written the script for a virtual reality game, A Killing at Hastings’ Rock. After software developer James Lindstrom is killed (irl), young computer whiz Alex (Shawn Phelan) tries to hack into Lindstrom’s password-protected files to figure out the secret behind a mysterious locked door in the Hastings’ Rock world. Jessica is right by Alex’s side. From the Murder, She Wrote episode “A Virtual Murder” (October 31, 1993):

“Oh, man, this — it's unreal. I've run my random character generator, my password algorithm. I've never met a computer I couldn't crack in less than ten minutes.”

“Alex, James Lindstrom was a genius, right?”

“Oh, he told you too, huh?”

“Often what stymies the rest of us about genius is its ability to reduce the complex to the simple, to the obvious. I mean, what about something basic, like “open door”?

[Types.]

“That's it! We're in!“

The screen shows the password as OPEN DOOR, space included.

“A Virtual Murder” is a hoot. In addition to extended glimpses of Jessica Fletcher wearing what purports to be a virtual-reality headset, there are repeated references to “source codes” (plural). Here’s an appreciative commentary on the episode.
