St Thomas’s Hospital is the London hospital where Cormoran Strike locates and interviews Rochelle Onifade, a friend of Lula Landry and a potential source of evidence about her death. Its outpatient psychiatric clinic provides the connection between the two women, while Rochelle’s history of illness and treatment sharpens a central tension in the investigation: psychiatric diagnoses may describe real needs and experiences, yet can also be used to discount a person’s account or presume a motive.

Setting and connection to the investigation

Rochelle’s file indicates that she is expected to attend an outpatient clinic at St Thomas’s Hospital. Robin Ellacott follows that lead, telephones the hospital while pretending to be Rochelle, and learns that Rochelle’s appointment is scheduled for 10:30 on Thursday morning. The discovery gives Strike less than an hour to reach the hospital and find her, turning the clinic’s routine appointment system into a practical route to a witness whom he has been trying to locate.

Strike arrives shortly after ten and checks that the automatic double doors on Grantley Road are the only entrance. He then takes up a position on a stone wall in the car park, about twenty yards from the entrance, where he can observe people going in and out. He knows little about Rochelle beyond the likelihood that she is homeless and the certainty that she is Black, so he watches the clinic entrance and calls her name as people emerge. The hospital is thus not merely a destination: its entrances, appointment time, and waiting area shape the method of the search.

Strike finds Rochelle

The search takes longer than Strike expects. He calls out to other Black women entering or leaving the building, but they are not Rochelle. Just after eleven, he sees a short, stocky woman leave with a distinctive side-to-side gait and wearing a conspicuous magenta fake-fur coat. Recognizing that she is the person he has been waiting for, he calls her name again and approaches. Rochelle stops, looks around, and regards him with mistrust.

The encounter begins under conditions that make trust difficult. Strike has found Rochelle by using information in a police file and by waiting outside a psychiatric clinic; his appearance and approach give her reason to be wary. He decides against taking out his notebook, believing that the formal act of recording the interview might make her withdraw or leave. Instead, he asks questions casually about how she came to attend the clinic and how she first met Lula. At first Rochelle gives monosyllabic answers, but she gradually becomes more forthcoming.

The clinic and Rochelle’s history

Rochelle explains that she met Lula through the outpatient clinic. Her own history includes early abuse, care placements, severe mental illness, foster homes, and violent outbursts; she became homeless at sixteen. She eventually received appropriate treatment after being hit by a car: when her unusual behavior made it difficult to treat her physical injuries, hospital staff called in a psychiatrist. By the time Strike speaks with her, she is taking medication that greatly eases her symptoms.

For Rochelle, the clinic is more than an appointment. Strike perceives that the outpatient group, where she met Lula, appears to have become the highlight of her week, and Rochelle speaks affectionately about the young psychiatrist who runs it. That detail gives the hospital a relational significance in her life: it is associated with treatment and routine, but also with a rare point of connection. It is through that setting that Rochelle and Lula become acquainted.

Diagnosis, testimony, and narrative significance

The hospital’s association with psychiatric care matters beyond Rochelle’s own history. John Bristow tells Strike that Lula had been diagnosed with bipolar disorder, that medication had controlled her condition, and that the autopsy confirmed she had been taking it. He argues that the police and coroner could not see past her history of poor mental health when they treated her death as suicide. Strike, however, does not accept the opposite inference that an apparently positive outlook proves a person could not have died by suicide: he recalls a previous case in which a man had appeared cheerful at a birthday party before taking his own life.

Rochelle also describes Lula as depressed and says that depression is an illness that can overwhelm someone. Her account differs from John’s insistence that Lula had not been depressed, but neither a diagnosis nor a witness’s impression alone resolves what happened. The investigation’s attention to mental health therefore remains a question of interpretation: treatment and symptoms are relevant circumstances, not automatic proof of a person’s intentions or the manner of her death.

The hospital setting brings that problem into focus without resolving it. It is where Rochelle receives care, where her acquaintance with Lula begins, and where Strike finds her through patient-related appointment information. The same place that makes a witness accessible also frames how others may judge her credibility. In the investigation, St Thomas’s Hospital links care, memory, and testimony while underscoring the limits of treating psychiatric history as a substitute for evidence.
