It’s just as well Curtis’ wife Susan was dead, otherwise she would have some embarrassing questions to ask, and they would be some explaining to do, as to Curtis’ death or disappearance. Of course they could have told Susan anything. He might have been killed somewhere behind the Iron or Bamboo curtains, considering the kind of work he did. Presumably he was a spy or espionage agent. However remembering that Curtis was seconded to The Village, which meant he was seconded from another department. That being the case, quite possibly there would still have been some embarrassing questions to answer.
Be seeing you
