A Ghost Hunter Sparks a Mystery in This New Hallmark Story
Hallmark Channel took to Instagram on Monday, May 18, to share the poster for “Haunted Harmony Mysteries: Key to the Castle.” Featuring Mowry-Housley and Cooper, the scene also shows a royal residence in the background that looks enticingly eerie.
As if that wasn’t enough to draw you into the story, Hallmark wrote in the caption of the post, “Every castle holds secrets. Some are buried deep. Some refuse to stay that way. 🗝️”
To pique your interest even more, you should know that “[w]hen a ghost hunter show comes to town, it’s up to Gethsemane and Eamon to solve the unexpected murder of the [show’s] host, allowing the brand-new spirit to cross over,” according to Hallmark.
“Tamera Mowry-Housley, Risteárd Cooper, and Marco Grazzini star in #HauntedHarmonyMysteries: Key to the Castle — premiering Saturday, May 30,” the IG caption continued. “Stream next day on @HallmarkPlus.”
