The contestants on Whodunnit?, ABC’s murder-mystery summer reality show, have one objective: to survive long enough to determine who the Killer is, as he/she picks off a new victim each week. But at least one member of the cast has been in a similar situation before.
Giles the butler (Gildart Jackson), is actually employed by the Killer, and guides the players through the game by delivering messages from the Killer and offering them clues along the way.
