Clare Mosley, the widow of broadcaster and author Dr. Michael Mosley, returned to the Greek island of Symi with their children on the anniversary of his death, she told The Sunday Times.

Dr. Mosley, 67, was found dead near the resort of Agia Marina last June, four days after he went missing while on a walk in temperatures reaching about 40 degrees Celsius. An autopsy concluded he died around two-and-a-half hours after leaving his wife and friends; a coroner later recorded that his death was most likely a result of heatstroke.

Clare Mosley said she and the couple's four children did not stay on Symi because previous searches for Dr. Mosley had taken them across difficult terrain and had been emotionally fraught. Instead, she said they visited the island on the anniversary and went to a monastery at the far end of Symi. "I've not grown up religious at all, but I find it comforting to sit on a pew," she told the newspaper.

According to accounts provided to police investigators and reported in autopsy findings, Dr. Mosley had arrived on Symi the day before the walk. He and his wife had spent the morning at a beach on the island's east with friends. Clare Mosley said she waved him off as he set out alone. When she returned to their villa that afternoon she found he was not there. His body was recovered about 260 feet from a beach bar after days of searching.

Clare Mosley has described the period since his death as one of profound grief compounded by other family losses. She told The Sunday Times that her father, uncle and a step-sister have died in the year since. In a May interview with the Daily Mail — her first since his death — she said she would remember her husband for his adventurous and unconventional spirit.

"Michael loved exploring," she said in that interview. "That was the joy of him. His death was in keeping with his life. He was a maverick, a bit of a risk-taker. He pushed boundaries. I loved him for that; it made him so special. He was unorthodox and just so brilliant."

Clare Mosley said she did not seek detailed knowledge of the circumstances of the death beyond being reassured that he had not been distressed. "All I really wanted to know was that he was not suffering or in pain. That is what mattered. And he was not distressed," she told the Daily Mail. She added that there was "no sense of anger" and that "no one did the wrong thing. It's no one's fault."

Dr. Mosley was a well-known presenter and writer, noted for popularising health and science topics on television and in books and columns. He had written for the Daily Mail since 2011 and became known for undertaking unusual personal experiments for scientific and documentary purposes.

Greek authorities carried out inquiries after his disappearance and recovery. Investigators and the coroner's report cited the high temperatures and the circumstances of his walk — including that he had no mobile phone and only a single bottle of water — in concluding heat-related illness was the likely cause of death.

Clare Mosley's return to Symi illustrates the private process of mourning and remembrance following a public figure's sudden death. She and her children chose to mark the anniversary at locations the family found meaningful, but did not remain on the island, saying the terrain and memories made a longer stay too painful.
