Alan Davies returns as the lateral thinking sleuth, this time investigating the disappearance of a young woman after spending the night in 'The Nightmare Room' of an old Gothic house. For 70 years, 'Metropolis' has guarded the secret of how a Harvard geneticist, Eli Mencken (Patrick Poletti), vanished after spending the night in an attic room where the malevolent spirit of a madman is said to dwell. Now, when magician Lance Gessler (Nicholas Boulton)'s beautiful young assistant Elodie (Jenna Harrison) goes missing after sheltering there from a storm, Jonathan Creek, alongside the ever sceptical Joey Ross (Sheridan Smith), sets out to solve the mystery.
