GR translation: You will want cause and effect.

[Mike Jing]

V663.19-22, P676.24-27   You will want cause and effect. All right.
Thanatz was washed overboard in the same storm that took Slothrop from
the Anubis. He was rescued by a Polish undertaker in a rowboat, out in
the storm tonight to see if he can get struck by lightning.

What does "cause and effect" refer to here exactly? I assume this is
directed to the reader and it refers to the happenings in the story
that follows. There is a perfect Chinese idiom for it, and I want to
make sure I have understood it correctly.
