Waitrose & Partners: Sweet Suspicion - A Deliciously Festive Whodunnit

A Masterclass in Suspenseful Media Strategy

Waitrose and Saatchi & Saatchi abandoned the traditional "food-porn" montage for a high-concept mystery that sustained a three-week cultural conversation. To treat the campaign like a prestige drama, MG OMD partnered with ITV to air teasers during high-stakes programming like *Until I Kill You*. The mystery culminated in a reveal during *I’m a Celebrity... Get Me Out of Here!*, ensuring maximum linear reach. This strategy resulted in over 150 million views and a 19% increase in the supermarket’s addressable audience.

Succession Meets the Garden Shed

Directed by BAFTA-winner Lucy Forbes, the production utilized a heavy-hitting ensemble cast to ground the comedy. Matthew Macfadyen channeled his detective repertoire as Detective David, supported by Sian Clifford and Joe Wilkinson. While the public focused on hero products like Brown Butter Mince Pies, the narrative centered on the theft of a No.1 Red Velvet Bauble Dessert. In a clever subversion of the genre, the actual culprit - Steve (Dustin Demri-Burns) - was the least suspected by the public, receiving only 8% of the vote in online polls.

Evidence Boards and Feline Suspects

The campaign extended into the physical world with an interactive "evidence board" at London King’s Cross Station, allowing commuters to analyze clues in person. In-store, Waitrose "Partners" wore t-shirts displaying their own suspect predictions to engage shoppers. Despite the detailed clues pointing toward Steve, the British public remained convinced of a different villain: Fig the Cat topped the official suspect polls with 18% of the vote. The engagement translated to a 4.5% sales growth, outperforming the overall market and attracting 1.5 million new shoppers.
