I've been catching up on iPlayer.
In the first interview when Juilen treated Tony as a suspect, there were only 9 minutes of Tony's movements unaccounted for. He sounded quite random about what he had been doing. It was, according to Julien, time enough for something to have happened in vicinity of pool/lake.
Malik the journo has told Emily he knows what they both did (ie both Hugheses). Was this covering up Ian's murder? After all employee said he'd simply vanished, and had been declared legally dead 8 years on. If his car had been found at house under renovation, or his blood in the boat, then would the suspicious nature of the disappearance be more widely known? Who could Tony trust, other than Emily, to help with cleaning up and moving cars so no-one ever though that's where an attack took place?
Ollie must have been abducted (or else the video footage is fake, but that brings far too many people into the conspiracy, and would also mean that Pronettoyage is being framed (for no-one would, if guilty, leave their company logo on a tape showing the boy alive).
But I am not convinced that Ian's abuse ring (which may include all sorts of french officials) had anything to do with an opportunist abduction of Ollie.
Was anyone else identifiable on the 52 tapes? Was Tony caught for assault/murder, but somehow 'exonerated' ?
