In the BMJ (subscription required), Dalrymple examines a book on the death of Dylan Thomas:

Dylan Thomas (1914-53) was a perfect poète maudit. He spent much of his
short life in dark bars, inhaling smoke and imbibing beer, often at
other people’s expense. Until I read David N Thomas’s book Fatal
Neglect: Who Killed Dylan Thomas? I (like most people) had always
assumed that he had more or less drunk himself to death. But Mr Thomas’s
theory is that he died from medical incompetence, and his case is a
good one.
