A Heart That Works

Rob Delaney's memoir recounts the illness, death, and enduring absence of his youngest son, Henry, who died of brain cancer at age two. Blending raw grief with dark humor, Delaney traces the arc of Henry's short life, the toll it took on his family, and the ways loss reshaped his understanding of love, mortality, and what matters.

Delaney opens in the present, describing his new habit of swimming in London ponds, something his lifelong fear of lakes would once have made unthinkable. His wife, Leah, had always been a lake swimmer and took to London's ponds during Henry's hospitalization. After Henry's death, the couple took a scuba-diving course. During a drill that required sitting maskless at the bottom of a pool in darkness, Delaney felt no fear, only a dark peace, reasoning that death would mean walking through the same door Henry had walked through. He articulates his compulsion to write about Henry: not to sanctify himself, but because he believes that if people felt even a fraction of his family's pain, they would understand what life is really about.

The memoir moves backward. In 2014, Delaney and Leah relocated from Los Angeles to London so he could film the sitcom Catastrophe. Leah was pregnant with their third child and knew almost no one in the city. Delaney recalls scouting the Whittington Hospital with their older sons, Eugene and Oscar, before Leah's due date. Henry was born there via water birth, a healthy and beautiful third boy. The first year was chaotic: three boys under five, Delaney working excessive hours, and Leah shouldering most of the parenting.

Henry vomited at Eugene's fifth birthday party when he was 11 months old. Initial visits to the emergency room and a gastroenterologist yielded no clear diagnosis. Over the following weeks, the vomiting intensified and Henry lost weight visibly. A family friend recommended Dr. Anson, an experienced private pediatrician, who asked whether Henry's vomiting was "effortless," occurring without retching or distress. Delaney confirmed it was. Dr. Anson ordered an MRI, suspecting something might be pressing on the brain's emetic center. While Delaney and Leah waited at a nearby café, the doctor rushed in and told them to return immediately. The MRI confirmed a large brain tumor near Henry's brain stem. Henry had just turned one.

The family was transferred to Great Ormond Street Hospital (GOSH). Mr. Elsawi, a brain surgeon, explained that the tumor was the size of an apple and likely wrapped around critical cranial nerves. An emergency surgery to relieve pressure was performed first, followed days later by a 13-hour operation to remove the tumor. Mr. Elsawi reported removing all visible tumor, but the surgery's effects on Henry's brain stem were devastating. Henry lost the ability to swallow, could not breathe unassisted, and was deaf in one ear from a severed nerve. He received a tracheostomy and would never eat by mouth again. He also lost the ability to cry for several weeks, so his parents cried for him.

Henry spent seven months at GOSH, first in the ICU and then in the Giraffe oncology ward, where he was diagnosed with a grade-3 ependymoma, a type of brain tumor. Because radiotherapy carries a high risk of permanent brain damage in children under three, the medical team chose chemotherapy. Henry developed Bell's palsy on one side of his face from nerve damage, giving him a lopsided but endearing appearance. Delaney refused to wear gloves when changing Henry's diapers despite warnings about toxic chemotherapy waste, unwilling for gloved hands to be the only ones touching his son. He delivers a passionate defense of the National Health Service (NHS), praising the staff who cared for Henry as a whole child, not just a patient.

During Henry's hospitalization, Delaney's sister Maggie called with devastating news: her husband, Tobias, had died by suicide in Boston. Tobias had been experiencing worsening depression and had twice checked himself into a hospital. Delaney, consumed by Henry's illness, had not intervened as forcefully as he otherwise might have. He flew to Boston for the funeral, then flew directly back to London and took a taxi to the hospital to hold Henry down during a feeding-tube repair. The compounding tragedies bound Delaney and Maggie in a shared landscape of grief.

Throughout Henry's illness, Delaney and Leah worked to protect their marriage, going on weekly dates even while Henry was in the ICU and reading aloud to each other in the evenings. Delaney conceived of the family as five fingers of one hand, insisting that no member could be neglected. Because Henry's tracheostomy prevented him from speaking, the family learned Makaton, a language program using signs, symbols, and speech. Henry signed enthusiastically, demonstrating that his cognitive abilities were unaffected by the surgery. After Henry's death, Delaney recorded a CBeebies Bedtime Story in Makaton, the first of its kind, breaking down in tears at the phrase "I'm cold and lonely" (102) but continuing because children with disabilities and their families deserved the representation.

After 14 months in two hospitals, the family fought a bureaucratic battle to bring Henry home, hampered by government underfunding of social care that left the local council unable to provide qualified home carers. Leah led the effort. Henry's bedroom was converted into a hospital room with oxygen equipment, monitors, and a feed pump. At home, Henry exploded into life: cruising on a scooter, dancing to pop music, communicating in Makaton, and playing with his brothers. Two charities, Rainbow Trust and Noah's Ark children's hospice, provided essential practical and emotional support.

In September, an MRI revealed that the cancer had returned. Leah grasped before Delaney did that further treatment was impossible: Henry could not fly to specialized radiation centers, the repeated general anesthesia would kill him due to his worsening central apnea (a brain-stem condition in which the brain stops sending proper breathing signals), and another surgery would only delay the inevitable. They decided to stop treatment. Doctors estimated three to six months. The family filled Henry's remaining time with joy: the park, the zoo, animal parties, and daily routines of care and play. Leah became pregnant almost immediately, and Henry was the first person they told.

Around January 9, 2018, Henry stopped fully waking up. The palliative care team prescribed morphine and gabapentin. Over nine days, his condition declined. On the ninth night, his blood oxygen plummeted and would not rise. The family carried Henry into the back garden under the stars. Leah bathed with him one last time. Around five the next morning, Henry opened his eyes, looked into Leah's eyes, and died.

Leah attended Henry's funeral pregnant with their fourth son, Teddy, who was born a few months later. In the memoir's final reflections, Delaney describes grief as a permanent band of black added to his emotional rainbow. He mourns the fading callouses on his fingers from operating Henry's suction machine, physical proof that his son was real and needed him. He watches his older sons carry their own grief: Eugene, who was six when Henry died, expresses guilt about having gone to school that morning; Oscar, who was four, cycles between being and not being the family's youngest child. Separately, Delaney's father was diagnosed with myelodysplastic syndrome (MDS), a blood cancer likely caused by Agent Orange exposure during his service in Vietnam. Delaney's parents, divorced for over 30 years, unexpectedly reconciled through the father's illness, an act of grace that made Delaney feel like someone's child again.

Delaney rejects the idea of a physical paradise where Henry waits. Instead, he imagines himself as a glass of water that will one day be poured into the same vast ocean where Henry's glass was poured, and they will mingle together forever.
