People can change the way they look. But voices stay the same.

The expression “People can change the way they look. But voices stay the same.” turns a practical observation about disguise into a way of recognizing continuity beneath altered appearances. In a conversation between Martha and Stig, it leads Martha toward the suspicion that a baby she heard years earlier is the same baby she has encountered again; elsewhere, the novel repeatedly makes spoken and recorded voices carry truths that people have hidden or delayed telling.

The Expression in Context

Stig demonstrates a phone’s GPS, camera, and recording functions, then asks Martha to record him speaking. After she plays back the recording, he makes the observation about appearance and voice. The exchange gives the maxim a concrete basis: a changed image may frustrate recognition, while a familiar voice can still connect a person to an earlier encounter.

The scene also sets voice against image without treating recognition as infallible. Martha replies that some voices do change, but thinks of the baby’s whimper over a walkie-talkie, which she remembers as unchanged. Her reply narrows Stig’s general claim into a particular sound that has persisted in her memory.

Martha’s Recognition

Martha explains that she has worked at the Ila Centre for seven years. The length of that experience gives context to her judgment when she tells Stig, “I swear it’s the same baby.” The conclusion is prompted by the connection she makes between the remembered whimper and the voice she associates with the baby now; the text presents it as her conviction, not as independent confirmation of the child’s identity.

Stig does not challenge her or supply an explanation. He simply nods, and Martha appreciates that response. The scene therefore makes listening itself significant: her recognition is voiced to someone who neither dismisses it nor pretends to know more than she does.

Voices as Evidence

The maxim resonates with the novel’s broader pattern of truth emerging through speech and its records. At Staten Prison, Johannes Halden finally tells Sonny Lofthus that Ab Lofthus did not shoot himself. The disclosure comes after Johannes has identified himself as Ab’s confidential informant, and its delayed delivery gives the spoken sentence the force of a confession that changes Sonny’s understanding of his father’s death.

Recorded voices can preserve evidence beyond the moment of speaking. Simon Kefas plays a sound file in which a man identifies an account in Dennis Limited’s name, registered in the Cayman Islands, and begins giving its number. Simon uses the recording as something he can offer in a negotiation. The voice is not merely a sign of personal identity here; it carries information that can implicate others and acquire practical value.

The novel also complicates the idea that simply hearing a person guarantees truthful understanding. At the Ila Centre, a chaplain recognizes why residents confide in Sonny: Sonny listens without reaction or judgment, while the chaplain suspects that his own religious purpose makes his listening seem to carry an agenda. The contrast distinguishes the act of hearing from the conditions under which someone chooses to speak. A voice may preserve a clue, but trust shapes whether a secret is spoken at all.

Written Testimony and the Limits of Recognition

Sonny’s letter to Martha recalls his father’s account of a drowning and the boy who briefly believed his father had been saved. That remembered story shapes Sonny’s reflection on loss and on the possibility that hope can be cruelly withdrawn. He then tells Martha that he has found his father’s diary, wonders whether Ab meant it to be discovered, and explains that he is going to disappear. The letter makes Sonny’s own voice a final form of testimony, while Ab’s diary offers a separate written record of the pressures and decisions behind the family’s history.

Together, these scenes give the expression a significance beyond physical disguise. Voices and records can join separated moments, unsettle accepted accounts, and carry recognition across time; yet the novel also shows that evidence must be heard, trusted, and interpreted. Martha’s certainty about the baby remains her own conclusion, while Johannes’s disclosure and Simon’s recording demonstrate how a voice can become consequential evidence in a larger search for truth.
