Seems like i have to add point three to my assumed FF-revelation:
3. Blaming MI5
Madeleine McCann witness so crucial cops sealed off entire hotel and swept the building for bugs while interviewing him
I really think this a group who are all complicit some how and they are trying to save their own backs by putting the blame on each other. They all claim they weren't friends with CB and didn't like him despite all meeting through each other. I think FF's 'new evidence' will be about HB, just my prediction. Maybe HB/MT/MS waited so long to speak up because CB had something on them and now he is in prison they don't feel threatened or have destroyed evidence before coming forward.
