Let's assume the list is real. That will mean Partridge is alive and not really associated with Tyger Tyger, rather their enemy. He is RJ - the only character that would need to bug the office due to lack of access (and faking his death).

The tattoo is not three dots, it's a tiger pawn but the female PI who died only saw the top part of it.

Smith, Haffner and McAllister die in the cottage explosion which is setup by RJ ofc.

The only sad thing with this theory is that the "fake and resurrect" thing is SOOOO old and something Patrick Jane shouldn't let happen. So if this is the case, PJ is an idiot and best ending would be if he was killed by RJ.
