Produced by the BBC and written by David Renwick, it stars Alan Davies as the title character who works as a creative consultant to a stage magician while also solving seemingly supernatural mysteries through his talent for logical deduction and his understanding of illusions.
After Maddy successfully campaigns to free a man she believes to have been wrongly imprisoned for murder, the elderly husband of the victim, a retired comedian, is found shot dead in his nuclear fall-out shelter.
The otherwise empty bunker is locked from the inside, which would suggest that the man shot himself, but he has crippling arthritis in his hands and could barely pour a drink, much less pull a trigger, so how did he actually die?
Suspects include the rather odd son, the air-headed daughter-in-law and assorted monkeys used for research, but what role does an envelope containing a copy of his book play in the investigation?
A painting disappears from a locked room and the owner, theatre critic Sylvester Le Fley, offers a large reward for its recovery, which tempts Maddy.
Jonathan is quick to announce that he knows how the theft was done, but will not explain due to his dislike of Le Fley, who recently published a negative review of Adam's show.
A judge on a police protection programme is killed by a rapier blade into the chest and after a brief struggle, but only his sleeping wife was in the room at the time, and the only evidence at the crime scene is a torn fingernail.
An illusionist, whose twin sister died when an escape trick went wrong and she was partially sliced in half, is found dead in her snow-covered garden after her husband witnessed her shooting herself.
As Jonathan looks into the man's real identity, his only clue being a package in the attic containing six books by a best-selling author, Maddy takes the opportunity to perform a disappearing trick of her own.
A former glamour model, now living quietly with her rich, older husband in the countryside, is seriously injured when her garden shed explodes, leaving her badly burned.
With Maddy gone to America on a book promotion tour, Jonathan teams up with Carla Borrego, a theatrical agent representing an escapologist who is being hired for Adam's show.
After an awkward break-up some months ago, Jonathan and Carla – now married to the producer of a Crimewatch-like television show – unite to investigate a serial killer who wears a Davy Crockett hat and kills people named after flowers.
However, things take on a new dynamic when the killer shoots at police during a reconstruction of a murder and escapes from a locked room while the only window was in full view of those present.
A pop star's husband is baffled as to how a woman he had an affair with can regrow a full head of hair barely two days after she had it all hacked off in a hoax kidnap ransom video.
A priceless Eastern porcelain monk (said to have a curse on it that will bring nothing but evil to its owners) is stolen in front of several witnesses, prompting Jonathan and Carla's discovery of a major case of sibling rivalry, a disfigured woman who resembles another person, and a twisted love affair.
Using his powers of deduction and belief that nothing is as it seems, Creek races against time to uncover a number of intriguing clues which lead him to the unbelievable truth and the revealing of one of the greatest acts of illusion he has encountered yet.
When a classic locked room mystery is turned into a West End musical, its female star falls victim to a real-life 'impossible crime', which Jonathan reluctantly becomes involved in solving.
