I think the thief could be nandani and we she escaped she went in the
easily in the car meaning quikly i think the so call 'nandani takur' could
have been the driver. anmd that is why no one was there at her place
when karan came over. she might be stealing info for abir. yes yes before
you guys bash me i think abir is her son but maybe not blood related it
could be that she adopted him like the way kt was adopted.
