The one with Keith Markham

I missed the end of the episode where Peter Firth played porn baron and pimp Keith Markham, who was trying to "go respectable" by getting into more legitimate businesses. I saw as far as where Denise Welch "busted" Kirsty as a cop, then the Vice team arrested Markham. But can someone please fill me in on what happened then? Was Markham successfully brought down, and did Kirsty's undercover activities have any consequences for her? Thanks very much.
