In the last scene of [A Patch Of Fog][1] we can see a present from Robert to Sandy Duffy.
Is there any indication or hint given to what is in that present?
I believe it could be the manuscript or the security cam footage but these are just wild guesses. 

The tag on the present has the following text:

> TO SANDY
>
> FROM ROBERT 
>
> MERRY XMAS
>
> DEATH TO ELEPHANTS

Here is a screenshot from the scene:
