In Dune (2021), on the directions of Vladimir with a bargain to release his wife,
Dr Yeuh betrayed Duke Leto's family:
Dr Yeuh: I jammed their comms and lowered their shields. I delivered
the Duke and his family.Vladimir: The bargain to the letter. And what was I to do for you?
Dr Yeuh: Deliver my wife from her agony.
What does "The bargain to the letter" mean?
Best Answer
Vladimir Harkonnen is dropping some words from the beginning of the phrase to make it sound more poetic.
What he's really saying, and would be understood is: "[You have followed] the bargain to the letter." Meaning that Yeuh has done exactly what was agreed upon when they made the initial bargain.
