first: to eliminate himself from the list and no one is gonna doubt.
second: wants to get jane busy to do what ever he wants and complete his plans.
third: he felt jane suspects him if you remember at E1 S6 .
I have been always thinking about partridge he looks psycho parching criminal to me another thing he enjoys explaining his crimes .
