Why it matters
The catapult tableau and wine-cellar climax make this one of Midsomer's most cheerfully excessive pieces of machinery.
Solicitor Nick Turner apparently takes his own life by walking from his roof on the same day neighbour Jack Wilmot disappears. Barnaby and Scott learn that a large sum is missing from a client account and that Turner's professional rivals have reasons to watch the fallout closely.
An elaborate killing involving a working model of a medieval catapult broadens the case, while wine investment offers another route for money to vanish behind specialist language. The detectives eventually find themselves locked inside a neglected cellar with the fraud's physical evidence.

Break a second seal: reveal the verified killer
Who was the killer in Hidden Depths? (spoiler)
Nick Turner · Felicity Turner (accomplice)Nick killed Jack Wilmot and used his body to stage Nick's own death, then killed Otto Benham and Mike Spicer in revenge for the fraudulent wine deal. Felicity helped construct and sustain the deception and is labelled as an accomplice rather than as the physical killer.
Verified motive
Nick killed Jack to fake Nick's own death and escape his financial collapse, then killed Otto and Mike in revenge for the fraudulent wine investment that had ruined him. Felicity helped sustain the false-death plan to protect them from exposure and its financial consequences.
Verified important clue
Archive case 41 · checked 16 September 2026Nick Turner's duplicate suit and shoesThe retailer remembers Nick buying two of every item in cash; combined with the photograph showing Nick and Jack's similar build and hair, the duplicate clothes expose how Jack's body could be passed off as Nick's while Felicity controlled the identification.
Verified decisive clue
