Short mission but good.
spoiler:I don't think the Mazarins were getting along too well. Sir Mazarin was obviously writing a note to his lover just before he was killed. There would be no reason for him to write a note to his wife telling her what he doing when he could simply go to the room and talk to her. For that matter, she should already know why they are at the Lambert's residence. Secondly, Lady Mazarin doesn't get upset at all when she discovers her husband's corpse. She freaks out at the site of most other bodies, though. In fact, nobody gets upset at the sight of the bodies of Marcus, Henderson, or Mazarin. Those guys must have really been unpopular.
