When a classic locked-room novel is turned into a West End musical, one of its stars falls victim to a real-life 'impossible crime'.
The Mystery of the Yellow Room, based on a 19th century story, is thrilling London theatre audiences with its enticing blend of music, romance and sizzling gothic melodrama.
But events take a sinister turn when the show's glamorous singing sensation Juno Pirelli is found horribly stabbed inside a locked dressing room, from which no assailant could possibly have escaped.
No weapon or any other evidence of an intruder can be found, nor any rational explanation for the victim's wounds.
As the actress's life hangs in the balance, her producer and colleagues remain baffled. And attention once again turns to the lateral-thinking Jonathan Creek for a solution to the whole grisly puzzle.
But can Creek - now a happily married man - even be persuaded to embark upon the investigation? As he and wife Polly struggle to come to terms with a sudden personal tragedy, a series of dark and disturbing family secrets are about to emerge that will throw the couple's whole world into turmoil...
