Kate Alice Marshall is an author who transitioned from young adult fiction to adult psychological thrillers with A Killing Cold.

The central revelation in A Killing Cold is that Theo Scott is actually Rowan Cahill, a child who witnessed a murder at the Dalton estate years earlier. The family patriarch Magnus orchestrated a cover-up, sending the traumatized four-year-old away with a new identity. The current murder victim, Olena, was killed by mistake—someone intended to kill Theo to protect the family's decades-old secret.

In A Killing Cold, fifteen-year-old Alexis Dalton accidentally shot Mallory after confronting her about an affair with Alexis's father. Magnus Dalton ultimately killed Mallory by stabbing her to control the situation and protect Alexis from exposure. This murder set off a chain of cover-ups including the disappearance of young Rowan (Theo) and Liam's death, creating the central mystery that drives the novel.

The Dalton family in A Killing Cold is concealing multiple interconnected crimes: Mallory's murder, Liam's accidental death, and the abuse inflicted by Nick on Mallory and young Rowan. Magnus Dalton orchestrated extensive cover-ups to protect family members and their reputation. Each family member—Louise, Rose, Nick, Vance, Trevor, and Alexis—carries guilt and secrets that make them complicit in maintaining these lies for decades.

A Killing Cold shares similarities with classic locked-room mysteries through its isolated mountain setting and snowbound estate that traps characters together. Like Agatha Christie's And Then There Were None or Lucy Foley's The Guest List, Kate Alice Marshall uses the confined setting to build claustrophobic tension. However, A Killing Cold adds a unique twist by connecting the protagonist's suppressed childhood memories to the family's dark history.

A Killing Cold takes place at Idlewood, the Dalton family's isolated mountain mansion retreat during Christmastime. Kate Alice Marshall creates an intensely atmospheric and claustrophobic environment with heavy snowfall that makes roads impassable. The estate includes multiple cabins named after dragonflies (Dragonfly, Red Fox), contributing to the winter thriller aesthetic. The cold, remote setting mirrors the chilling family secrets and creates constant tension throughout the novel.

A Killing Cold centers on Theodora "Theo" Scott (actually Rowan Cahill) and her fiancé Connor Dalton. The wealthy Dalton family includes authoritarian grandmother Louise, suspicious Rose, controlling Magnus, hostile Uncle Nick, spoiled Trevor, and sympathetic Alexis with her wife Paloma. Secondary characters like Vance, the housekeeper Irina, and murder victim Olena all play crucial roles in revealing the interconnected secrets that define the family's dark history.

Some readers found A Killing Cold overly complicated with too many plot twists and revelations that felt overwhelming. Critics noted the premise requires suspending disbelief, particularly regarding the speed of Theo and Connor's engagement and the coincidental nature of their meeting. A few reviewers felt Kate Alice Marshall tried too hard to manufacture suspense through repetitive pacing, though most agreed the atmospheric setting and character development compensated for these weaknesses.

A Killing Cold epitomizes the winter thriller genre through its snow-covered mountain setting, Christmas holiday timing, and blizzard conditions that isolate characters. Kate Alice Marshall uses cold weather imagery and the claustrophobic atmosphere of being trapped indoors to amplify psychological tension. The killing cold of the title operates both literally—as a character dies in freezing conditions—and metaphorically, representing the Dalton family's emotionally frigid dynamics and calculated cruelty.
