With only four contestants remaining on ABC's murder mystery show Whodunnit?, The Killer is getting a little more "experimental" with his riddles.
This week, Giles the Butler (Gildart Jackson) teases the remaining players — Melina, Cris, Lindsey and Kam — with a science project from the killer. Could a container of exploding ping-pong balls provide a clue into Ronnie's death last week?
See if you can pick up on any hints in this exclusive clip from Sunday's episode. Who do you think The Killer is?
Whodunnit? airs Sundays at 9/8c on ABC.
