What was the Section actually covering up?
Maybe I wasn't paying enough attention, but I couldn't actually figure out exactly what the Section was covering up. There was a reference to a 'constitutional crisis' more than once, but I don't recall it ever being explained - and it certainly didn't seem to bother anyone else in terms of arresting them and bringing it all out into the open. Was it simply that their defector became involved in criminal activities and they didn't want the connection to come out? Hardly a constitutional crisis - and wouldn't it have been easier simply to kill him (which is what they did in the end anyway) and make it look like a gangland hit? Or were they simply trying to protect their own anonymity? Did the book explain it better?
Basically, I liked the first story (TGWTDT) but the next two (which were basically parts 1 and 2 of the same story) didn't really do it for me.
