Not only make-believe …

In 1958, another impostor entered Trevor-Roper’s life. At that point, he was claiming to be the Reverend Robert Peters, a highly qualified and recently married postgraduate student at Magdalen College, Oxford. Further investigation revealed, however, that his name was not Peters, that he had been stripped of holy orders, that his qualifications were false and that his marriage was bigamous. Only his status as a postgraduate student was true – and the discovery of these malfeasances soon ended that.
