The beloved Irish mystery series Harry Wild is back for its fourth season, premiering May 5, 2025, exclusively on Acorn TV. Jane Seymour reprises her critically acclaimed role as Harriet “Harry” Wild, the sharp-witted, recently retired English professor who just can’t resist solving crimes—much to the frustration of her detective son, Charlie (Kevin J. Ryan).
This season, Harry dives into her most dangerous cases yet, uncovering dark secrets, hidden betrayals, and unexpected connections that challenge her brilliant mind. With her unconventional sidekick Fergus (Rohan Nedd) by her side, Harry navigates Dublin’s criminal underworld with her signature mix of literary wit and fearless determination. But as the stakes rise, will her meddling finally put her in real peril?
