Chapter 1 Summary

Alex Easton—a Sworn Soldier from Gallacia—and their batman, Angus, travel to the United States at the request of Easton’s friend and fellow veteran, Dr. James Denton. Easton resists explaining the concept of a Sworn Soldier—a person, born female, who assumes a non-binary military role and adopts one of Gallacia’s neutral pronouns, ka/kan—to the surrounding Americans, whom they anticipate would not understand. Though apprehensive about what nightmares may await, Easton feels compelled by loyalty. During the journey, Easton tries to avoid imagining the worst, though anxiety about the unknown lingers beneath their restraint.


When they arrive in Boston, Easton and Angus are met by Kent, Denton’s assistant, who escorts them to a hotel where Denton and another associate, Mr. Ingold, are waiting. Easton notes the hotel’s excessive use of mauve. There, Easton meets Mr. Ingold, an Indigenous American with a heavy Boston accent. Denton explains that his cousin, Oscar, has disappeared while exploring an abandoned coal mine near Shaversville, West Virginia on property owned by the Denton family. Denton confesses that he sought Easton’s assistance because he believes the situation to be supernatural. Easton recalls past horrors with unease, but Denton clarifies that he does not suspect another fungal infestation, but rather “more lights in the deep” (8).

Chapter 2 Summary

Denton explains that his cousin, Oscar, traveled to Hollow Elk Mine to search for coal. The mine has a reputation for being cursed and was previously plagued by accidents, which led workers to abandon it. Visibly emotional, Denton describes Oscar’s longstanding fascination with caves, recalling that as a child, Oscar once returned to a cave in which he had previously been trapped. Denton shares several letters Oscar sent from the mine.


In his correspondence, Oscar reports a series of unsettling occurrences. He first describes hearing “squelching” sounds and discovering missing supplies, insisting that his assistant, Roger, had not taken them and that Roger’s watchdog, Thunder, had not alerted them to any intruders. Oscar later recounts seeing a red glowing light within the mine, explaining that it appeared on the other side of a “squeeze.” Ingold clarifies for Easton that a squeeze is a narrow passage supported by beams or pillars. Easton feels anxious, reflecting: “I could just imagine the weight of all that rock overhead, pressing down, squeezing” (15). In a subsequent letter, Oscar describes finding an undulating, spiraling tunnel that led to a cavern with a strange, pearl-like floor. He concludes by asking Denton to join him at the mine.


Denton says that he traveled to Hollow Elk Mine but found it deserted. Upon returning home, he received a lengthy telegram from Oscar stating that he had become ill from gases in the mine and insisting that the site was of “no interest.” Since that message, Oscar has not written again.


The group offers possible explanations for Oscar’s silence. Angus suggests that Oscar may be embarrassed, while Easton and Ingold propose that he may have been murdered. Denton rejects the idea of Roger as a suspect, insisting that he is loyal and illiterate, and therefore incapable of sending the telegram. Although Denton admits he wishes the matter were as simple as murder, he recalls experiencing a strange sensation while in the mine, likening it to the feeling associated with the home of their mutual acquaintance, Usher. Easton agrees to travel to the mine.

Chapter 3 Summary

The group departs the following day. During the train journey, Denton privately asks Easton how they would prefer their gender identity to be addressed. Rather than explain the cultural concept of Sworn Soldiers, Easton says that they are content to allow others to assume they are a man and chooses not to elaborate on Gallacia’s system of pronouns. Privately, Easton reflects on the diversity of those pronouns, including the sha/shan form used for rocks.


Easton finds the journey across the United States longer than anticipated, noting the country’s size in contrast to Europe. When the train jolts unexpectedly, Easton experiences a brief flashback and reflects that both they and Denton have long suffered from “Soldier’s heart.” Along the way, Easton observes stretches of striking natural beauty as well as areas damaged by industrial development. Ingold criticizes the world’s heavy reliance on coal and explains that he is a chemist involved in multiple independent pursuits, remarking, “I dabble in things” (27). Denton, however, describes him more emphatically as a “genius.”


Ingold outlines the potential dangers of the mine, identifying noxious gases as the primary threat, including explosive “firedamp” and suffocating “blackdamp.” He notes that the ventilation shafts should help improve air circulation. During the discussion, Easton observes tension between Denton and Ingold but concludes that it is “none of [their] business” (29).


After arriving in Shaversville, the group saddles horses for the remainder of the journey. Easton dislikes the Western saddle, finding it bulky and uncomfortable, particularly because of the prominent saddle horn. They reflect on how much they miss their own horse, Hob, who remains boarded in Paris.

Chapters 1-3 Analysis

These early chapters of What Stalks the Deep orient readers in Kingfisher’s world. Before the central horror of Hollow Elk Mine emerges, Kingfisher situates the narrative within the shadow of prior traumatic events. In the opening, Easton’s reflections on his friendship with Denton—“There are some experiences that bond people together more closely than blood, and the nightmare we’d faced had been one of them” (2). Their subtle reference to the events in Ruravia serves both returning and new readers, establishing continuity with the previous books in the series and signaling that Easton and Denton enter the narrative as trauma survivors. These allusions to the earlier books in the Sworn Soldier series foreground Kingfisher’s thematic exploration of How Trauma Shapes Threat Perception. When Easton reflects on the sentient fungus they once faced—"The only reason that I slept at night was because we had destroyed it. I did not want there to be another one” (8)—the lingering psychological impact of their past experiences becomes clear. Easton, having endured war and multiple supernatural traumas, now anticipates horror.


The opening chapters reintroduce Easton through voice and tone. Humor and irony dominate their observation of the United States. After being frequently misidentified as a man, Easton notes, “They were wrong about the man part, but the thought of explaining Gallacia’s sworn soldiers to a boatload of Americans was so exhausting that I needed a gin and tonic just to contemplate it” (1). The emphasis is on exasperation rather than outrage, and Easton, anticipating misunderstanding, chooses practicality over confrontation. The aside that it took “a second [gin and tonic] to decide that explaining it would be a bad idea” (1) frames identity disclosure as labor. Similarly, the wry comment that “One American can really fill a room. I assume it only takes a hundred or so to really fill a country” (3) establishes Easton’s position as a cultural observer.


This cultural positioning expands beyond pronouns to broader social norms, introducing the novella’s thematic focus on American Conformity Versus Otherness. Easton’s remark about their sister—”my sister has a regrettable belief that if I just hold one [baby] long enough, I will come to enjoy it. I will not” (2)—extends the theme of social norms into domestic life. Easton’s refusal is calm but definitive, reflecting broader social expectations surrounding reproduction. Together with the narrative shift from ka/kan pronouns in earlier books to they/them here suggests language and behavior are shaped by context, and Easton adapts while registering constraint. This framework also informs the depiction of Denton and Ingold. Easton observes that “Ingold, at least was so pointedly not touching Denton that the space between them practically glowed. Which was interesting, and also none of my business” (29). This deliberate avoidance by all three characters suggests awareness of social boundaries, reinforcing the atmosphere of restraint that characterizes the American setting.


Trauma remains the interpretive lens through which the narrative is conveyed. Easton frames Denton’s need for them in explicitly experiential terms: “what bothered me was the idea that whatever trouble Denton was in, it was the sort of trouble that required Angus and me to cross an ocean […] Denton needed the two people he knew with experience in nightmares” (2). For Denton, Easton’s prior experience with supernatural events makes them an indispensable asset in confronting an unconventional threat. Later, when Denton remarks that the situation feels like “standing in Usher’s house again” (20), the comparison collapses past and present. The mine though is not yet explored, is—for Easton and Denton—already haunted. The early chapters demonstrate how trauma narrows one’s interpretive possibilities, as Easton imagines the horrors they may face in relation to their past experiences.


In parallel, Kingfisher introduces the industrial landscape that underpins the narrative’s ethical tensions, laying the groundwork for Kingfisher’s examination of The Human Cost of Extractive Industry. Ingold explains that “Everything here runs on coal […] The North ramped up production in West Virginia to compensate and never stopped” (9), situating the story within the shadow of extractive industry. Easton’s travel observations reinforce this backdrop: “And then you’d hit a valley and suddenly everything would be stripped away […] And next to that would be a ramshackle little town […] kept from being a slum by the sheer willpower of the people who live there” (27). The juxtaposition of environmental degradation and communal resilience complicates the setting. Rather than reducing mining communities to victims, the narrative foregrounds endurance.


Chapters 1-3 establish the interpretive framework of What Stalks the Deep. Cultural negotiation, restrained intimacy, industrial exploitation, and the ongoing consequences of trauma converge to create a landscape primed for crisis. Kingfisher waits to escalate into horror, encouraging the reader to understand how the characters will respond once the horror begins.
