It was kind of a trope that Corky would bite the dust and be blamed for all the leaks. I remember seeing this trope in an episode of 21 Jump Street where Johnny Depp's character goes undercover, and ends up getting ingratiating himself in the gang by accusing another of being a snitch. I really like The Night Manager and it's a shame season 2 has kind of got stuck in development hell last I read.
