I vaguely remember a story about a sinister organization that controlled people in some sort of hive. The authorities investigate it but underestimate the problem initially, thinking it's just some sort of cult.

They might have had vats to recycle people?

I specifically remember a part about a female hive agent trying to seduce information from an investigator, accidentally fucking him to death (he gets an heart attack) - his colleague wonder about what kind of weapon was used.
