Safe on Netflix - spoilers

[Peopleplease]

Just finished this. Thought it was good. One quick thing I missed - the guy who died - Chris, who broke into his parents place while Helens House was burning down?? Was it Bobby?

Hmm. Good point! I'm not sure.

Also they wouldn't have taken The murderer there. They'd have taken them somewhere they weren't known.

(Trying to keep it slightly vague!)

Oh yes! I don't think they addressed this! I suppose it must have been Bobby, but what was he looking for - the tape?
