Murder in a Small Town Season 2 cast complete guide

1. Rossif Sutherland as Karl Alberg

Rossif Sutherland embodies the world-weary yet deeply competent core of the series as Karl Alberg, a man haunted by the traumas of his big-city policing past. Sutherland’s performance is a masterclass in restrained intensity, conveying Alberg’s sharp intelligence and inner turmoil through a quiet, observant demeanor rather than overt dramatics. He is a man trying to outrun his own nature, only to find that his talent for seeing the darkness in people is both his curse and his greatest gift.

In Season 2, Sutherland will delve deeper into Alberg’s ongoing struggle to reconcile his desire for a peaceful life with his undeniable calling as an investigator. As the murders become more personal or intricately tied to the town’s hidden secrets, we see the psychological toll it takes on him. Sutherland expertly portrays a hero who is not invincible but is relentlessly driven by a need for justice, making him a profoundly relatable and compelling anchor for the series.

2. Kristin Kreuk as Cassandra Lee

Kristin Kreuk returns as Cassandra Lee, the town librarian and Karl Alberg’s love interest. Kreuk brings a wonderful warmth, intelligence, and independent spirit to the role, making Cassandra far more than just a love interest; she is a pillar of the community and often a source of crucial local insight for Alberg’s investigations. Her calm presence provides a necessary emotional anchor and a glimpse of the normal life that Alberg is fighting to protect.

Kreuk’s chemistry with Sutherland provides the show with its heart. Their relationship represents the central conflict of the series: the choice between a quiet life and a calling to confront darkness. Cassandra’s perspective often grounds Alberg, and her own storylines ensure she is a fully realized character with her own agency, dreams, and connection to the town’s mysteries.

3. Aaron Douglas as Sid Sokolowski

Aaron Douglas, known for his iconic role in Battlestar Galactica, brings grit and a dry wit to Staff Sergeant Sid Sokolowski, the head of the local RCMP detachment. Douglas perfectly captures the essence of a dedicated, pragmatic cop who has a deep respect for Alberg’s skills, even if their methods sometimes differ. He represents the official law enforcement arm, often serving as the bridge between Alberg’s unofficial consulting and the procedural requirements of a murder investigation.

Douglas provides a fantastic foil for Sutherland. Their partnership is built on mutual respect and a shared goal, though often tested by jurisdictional boundaries and different approaches. Sid’s deep roots in the community provide essential context for the cases, and his character adds a layer of procedural authenticity and gruff charm to the narrative.

4. Savonna Spracklin as Isabella Harbud & Fiona Vroom as Phyllis Diaz

Savonna Spracklin and Fiona Vroom appear as Isabella Harbud and Phyllis Diaz, respectively. These characters are likely residents of the small town, each holding their own secrets and connections to the various cases. One might be a local business owner, a council member, or a figure from someone’s past. Their presence is vital for building the rich tapestry of the community, serving as sources of information, potential red herrings, or even suspects as Alberg peels back the layers of each mystery.

Their roles, while supporting, are essential in creating the authentic “small town” feel where everyone is connected and everyone has a story. An interaction with a character like Isabella or Phyllis could provide the crucial clue that breaks a case wide open, or it could send the investigation down a misleading path, adding to the suspense and complexity of each episode.

5. Dakota Guppy as Holly Alberg & Alisha Newton as Devon Travis

Dakota Guppy returns as Holly Alberg, likely playing Karl’s daughter. Her character introduces personal stakes and a glimpse into Alberg’s life before the small town, reminding him of what he left behind and what he’s fighting for. Alisha Newton (Heartland) joins the cast as Devon Travis, a new character whose details are under wraps but could be a summer resident, a newcomer causing a stir, or a young person connected to a victim.

These younger characters represent the future of the town and the impact the crimes have on the next generation. A character like Devon could be a witness who saw something she shouldn’t have, or her arrival could be the catalyst that disrupts the town’s fragile equilibrium, setting the season’s mystery in motion.

6. Bethany Brown

The talented Bethany Brown joins the cast in a role that is sure to be significant. Given the show’s structure, she could portray a victim’s grieving relative, a suspect with a compelling alibi, or a new professional in town like a journalist or doctor. Brown is a versatile actress capable of adding depth and intrigue to any role she takes on.

Her character will be woven into the seasonal mystery, providing emotional weight, key information, or misdirection. Whether she is seeking justice for a loved one or hiding a dark secret, her presence will undoubtedly contribute to the compelling web of relationships and suspicions that define the show.

7. Marci T. House as Dr. Angela Clyburn

Marci T. House appears as Dr. Angela Clyburn, almost certainly the town’s medical examiner or a specialist brought in on a case. House brings authority and intelligence to the role, providing the crucial scientific facts that guide Alberg’s investigation. Her character is the voice of empirical evidence, delivering findings about time of death, murder weapons, and cause of death that often confirm Alberg’s instincts or send him in a new direction.

Dr. Clyburn’s interactions with Alberg and Sokolowski will be key procedural moments in each episode. Her expertise adds a layer of scientific credibility to the investigations, and her no-nonsense professionalism makes her an invaluable, if occasionally skeptical, ally in the pursuit of the truth.

8. Marcia Gay Harden as Mayor Christie Holman

Academy Award winner Marcia Gay Harden is a major new addition to the cast as Mayor Christie Holman. Harden is a master at portraying sophisticated, intelligent, and formidable women, making her perfect for a political figure in a town rocked by crime. Mayor Holman is likely deeply concerned with the town’s image and economic stability, creating a fascinating dynamic where her political interests often clash with Alberg’s uncompromising pursuit of justice, no matter where it leads.

Harden’s presence elevates the drama and stakes immensely. Mayor Holman could be a powerful ally who provides resources or a formidable obstacle who tries to steer the investigation away from the town’s most powerful citizens. Her character introduces themes of political power, corruption, and the difficult choices between what is right and what is convenient for the greater good.
