At The Cottage in Laguna Beach, an unsigned note turns Dom Corvaisis’s private sleepwalking into a question about his past. It arrives beside the advance copy of his first novel, but its two sentences unsettle him more deeply than the book delights him: “The sleepwalker would be well-advised to search the past for the source of his problem. That is where the secret is buried.” The message offers no sender, evidence, or explanation. Its force lies in naming the possibility that Dom’s present condition has a buried cause—and in leaving him to decide whether the warning can be trusted.

The first warning

The note reaches Dom while he is having breakfast at The Cottage, a popular restaurant on Pacific Coast Highway. He has just opened the padded envelope containing his advance copy of Twilight in Babylon and is absorbed by the book when he turns to the rest of his mail. The contrast is immediate: the novel is a tangible achievement he can hold beside his plate; the anonymous sheet directs him toward a past he cannot remember. On reading it again, he feels a tremor and coldness at the back of his neck.

The message follows him after breakfast. Sitting in his car, with the novel forgotten on the seat beside him, Dom reads the note repeatedly and becomes so nervous that he nearly takes a Valium from his jacket pocket. He stops before swallowing it. To consider what the letter might mean, he decides, he needs a clear mind; for the first time in weeks, he puts chemical relief aside. At South Coast Plaza, while waiting for Christmas gifts to be wrapped, he continues to take the note from his pocket and reread it. Its anonymity does not diminish through repetition. It makes the ordinary acts of shopping and waiting into intervals in which the message keeps returning.

An authorship he cannot establish

Dom initially considers whether Parker Faine sent the note to shock him out of his drug-induced haze. He rejects the theory: theatrical amateur psychotherapy might seem possible, but such manipulative maneuvering does not fit Parker’s character. The question becomes more disturbing when Dom lists the only people who know he sleepwalks: himself, Parker, and Dr. Cobletz. He has ruled out Parker and is sure that Dr. Cobletz did not send it. That leaves the possibility that he wrote the warning himself without remembering it—or that someone else knows more about his condition than he thought.

At home, Dom tests the self-authorship possibility rather than accepting or dismissing it. He types the two sentences on his IBM Displaywriter, prints them, and uses the three additional printwheels he owns to make four copies in different typefaces: Prestige Elite, Artisan 10, Courier 10, and Letter Gothic. He labels and compares them against the original. Courier 10 appears to match, a suggestive result that still proves little: the same typeface is widely available. The paper is similarly inconclusive. Both sheets are ordinary twenty-pound, 8 1/2-by-11-inch stock, with no watermark or identifying feature that would show whether the original came from his supply. His painstaking comparison narrows nothing to a secure answer. The letter can be made to look like his work, but it cannot be traced to him.

The uncertainty sharpens into two questions: who besides Parker, Dr. Cobletz, and Dom could know about the sleepwalking, and what suppressed trauma or forgotten event might lie behind it? Dom grows tense while staring out at the night beyond his study window, and the desire for Valium returns. He resists again. The note has not supplied a memory, but it has changed the terms of his anxiety: instead of merely seeking escape from his symptoms, he has begun to look for their source.

A second message and a widening pattern

That night, Dom realizes he has not collected the mail from the curbside box. Among advertising flyers and Christmas cards is another plain white envelope without a return address. He opens it in his study and finds a single sheet bearing just two words: “The moon.” The abruptness of the message shocks him. It offers no explicit connection to the sleepwalking note, yet its arrival from the same anonymous, untraceable world makes the first letter feel less like an isolated provocation and more like the beginning of a sequence.

A later envelope postmarked New York contains no note, only two Polaroid photographs. One shows a young priest with an unnaturally empty expression; the other shows a woman Dom recognizes without being able to recall where they met, restrained in a narrow bed with an IV in her wrist. Their appearance intensifies the unease already set in motion by the letter. The succession of a written instruction, the cryptic lunar phrase, and disturbing photographs provides Dom with fragments, not a reliable account. Their meaning must be assembled, and the possibility that his own recollections have been compromised becomes part of the investigation.

From private suspicion to an investigation

When Dom later discusses the possibility of brainwashing with Ginger Weiss, she initially reasons that an imposed memory gap ought to reveal the days spent in custody. The answer undermines that assumption: false recollections could be implanted to cover the missing interval. In a hypnosis session with Pablo Jackson, Ginger cannot genuinely recall books and television programs she claims to have used to fill time at the Tranquility Motel. Pablo concludes that these are artificial memories, reinforced by post-hypnotic suggestions, rather than convincing recollections of lived experience. Pressing her for details makes her tense; her voice remains flat as she supplies programmed responses. The scene gives the anonymous warning a framework: a person may have a past concealed not by a clean blank, but by a substitute story.

Dom and Ginger then search old issues of the Elko Sentinel, looking beyond the reported toxic spill and evacuation for seemingly unrelated stories that might point toward what happened during the closure of Interstate 80. They identify Thunder Hill as a likely source of the crisis and Shenkfield as a misdirection. At the motel, Dom also argues that witnesses such as Elroy and Nancy Jamison may remember being evacuated because that is what they were made to remember; in his account, they too could have been held and brainwashed with the others. These claims are presented as an investigation’s developing theory, not as proof supplied by the anonymous letter. The note’s lasting importance is that it directs attention away from symptoms alone and toward the possibility of a deliberately obscured history. As the witnesses reunite, their similar nightmares of restraint and decontamination-suited attendants, and their attempts to recover events together, turn Dom’s solitary suspicion into a shared search for the truth.
