Remus is right: if they'd had any idea at all, they'd have had the floo reset to send anyone coming through straight to Truncheon before you had any notion of what was happening.

They got loads of leads from that Crimson Company bust, most of them the sort of very dull dead end you want followed up on by someone you keep around for precisely that sort of thing. If it looks interesting, you send for backup, which is precisely what the Enforcer who came tonight did.

Fortunately.
