Secret Sharing
4.1 Two out of Three Musketeers
In Bob's Manhattan living room, three high school chums are con-
fronting a middle-age crisis over scotch and soda. They're all lawyers
and disenchanted by the way that money and corruption have ru-
ined the justice system. Inspired by movies like
Batman
, they decide
to recreate
The Three Musketeers
and prowl about the night looking
for people in need of help.
Bob:
Okay. It's settled. We'll file for our license to carry con-
cealed weapons tomorrow. On Friday, we pick out our
Glocks.
Harry:
Yes. 9mm.
Together :
All for one and one for all!
Harry:
You know, I just thought of something. My wife promised
her cousin we would go to dinner at her house on Friday.
She planned it last month. Could we get the Glocks an-
other day?
Bob:
Sunday's out for me. We're going to my mother's house
after church.
Mark:
Well, doesn't fighting evil count for something in the eyes
of God?
Bob:
Yes. But I still think we need a contingency. We're not
always going to be available. There will be business trips,
family visits, emergencies.
Mark:
This is a good point. We might be stuck in traffic or held
up in court. We need a plan.
Harry:
Well, what if we said, “All available for one and one for
who's there that evening?”
