My friend Gavin Selerie, who has died aged 73, was a writer whose collections of poetry included Azimuth (1984), Roxy (1996), Le Fanu’s Ghost (2006) and Hariot Double (2016).
Favouring long-form verse, Gavin liked to think of his volumes as research projects that involved original academic analysis. Le Fanu’s Ghost, for instance, was based on family history of the Irish writer Sheridan Le Fanu, while Hariot Double brought together his wide-ranging knowledge of the Renaissance with his love of music and a fascination with London by juxtaposing the Elizabethan-era polymath Thomas Harriot with the modern jazz saxophonist Joe Harriott.
