‘Haunted Harmony Mysteries’ — Will Hallmark Continue Franchise After ‘Buried at C?’

As Hallmark Channel premieres “Haunted Harmony Mysteries: Buried at C” on October 12, 2025, sleuthers are likely hoping that the second movie in the franchise isn’t the last.

Good news! It appears two more “Haunted Harmony Mysteries” starring Tamera Mowry-Housley, Marco Grazzini, and Risteard Cooper are on the way — with one movie already filmed and another filming now in Ireland. That means the gap between movies shouldn’t be nearly as long as the two years between the first, 2023’s “Murder in G Major,” and the latest installment.

While promoting “Buried at C” with Grazzini, Mowry-Housley let it slip during an interview with “Good Day Sacramento” on October 8 that they were in Ireland filming a fourth movie.

When she, Grazzini, and Cooper returned to Ireland in early 2025 to film “Buried at C,” there was plenty of time on their shoot schedule to film a third installment — though it’s not clear what it will be called or when it will be released.

According to Ireland’s Screen Crew and Services Database, the cast and crew were scheduled to film for more than two months, from February 4 to April 11, in Dublin and in picturesque Wicklow, located about 30 miles south of the city. Given that most Hallmark movies stick to a 15-day production schedule, the cast and crew were able to film two new movies based on Alexia Gordon’s Gethsemane Brown Mysteries five-book series.

What Are the ‘Haunted Harmony Mysteries’ About?

Hallmark

In the first “Haunted Harmony Mysteries,” we meett main character Gethsemane, a former orchestra conductor living in Ireland to teach at a boarding school, St. Brendan’s, where she’s tasked with turning a motley group of students into an award-winning chorus.

However, when she keeps hearing the same four notes playing in the old Irish house where she’s staying, she discovers it’s the ghost of one of her music idols, a songwriter-musician, Eamon (played by Cooper), who perished years before in a mysterious murder-suicide.

Able to see his spirit, Gethsemane reluctantly starts working with him to try to solve the mystery and clear his name. She gets assistance from local Inspector O’Reilly, played by Adam Fergus, and her teaching colleague Griff (played by Hallmark fan favorite and “Virgin River” actor Grazzini.).

In the synopsis for “Buried at C,” Hallmark says, “Beloved music teacher Gethsemane Brown returns to solve a new case that hits a little too close to home when her brother, Jackson, is implicated in the murder of local troublemaker Ray.”

The logline continues, “Gethsemane and spirited partner Eamon join forces with Captain Mac, now a ghost after Ray killed him to cover up the theft of a violin recovered from the Titanic. As the investigation progresses, Gethsemane dives into a tangled web of secrets, stolen artifacts, and family drama to clear her brother’s name, all while navigating her own romantic entanglements.”

“Haunted Harmony Mysteries: Buried at Sea” premieres on October 12 at 8 p.m. Eastern time, and will be available to stream via Hallmark+ the following day.
