Nick Utechin obituary
BBC Radio 4 producer with an impressive sideline in Sherlock Holmes scholarship...Nicholas Rathbone Utechin was born in Oxford in 1952, the only child of Professor Sergei Vasilievich Utechin, who wrote and lectured on Russian history and political thought, and
Pat Utechin (neé Rathbone), who was Sir Isaiah Berlin’s personal assistant. His parents later separated.
That he was third cousin twice removed to Basil Rathbone, for many years the definitive Holmes on screen and radio, was for Utechin a lasting badge of honour. He attended Bryanston School and Glasgow Academy before reading modern history at University College, Oxford...
Nick Utechin, radio producer, was born on January 11, 1952. He died of cancer on August 17, 2022, aged 70
