Detective Inspector Adrian Fell, a highly respected police officer, seems to be the ideal subject for an Eyes and Ears profile. He even solves the locked room mystery of a dead judge faster than Jonathan Creek might have.

But then damning evidence of Fell's involvement with the death of a barrister is discovered. A reporter is tipped off and witnesses the officer at the scene of the crime, seemingly staring at the body and stealing evidence. Is he, in fact, a ruthless killer? Is Carla in danger? Is Jonathan getting too close to the truth? And what sinister secret is contained within Fell's strange chequered box...?

Does a piece of chewing gum that moves from one plant pot to another, and a piece of David Blaine style endurance magic from Adam, provide the answer?
