This is Partridge's voice listen to this Mentalist - All Brett Partridge appearance - VOSTFR,
same voice and the fact that we see a bald head !!! ( he change his
appearance and fake his death ) like in Agatha Christie novel Ten Little
Indians the killer is already dead, but in this case he fake is death.
And the Tiger Tiger thing it's only to give PJ a bone, to focus on something else
