According to Russel Miller’s biography of ACD “The Adventures of Arthur Conan Doyle’
(Thomas Dunne Books, 2008) page 451, Doyle claimed he ‘turned down a proposal from
Joseph Conrad, who had died in August 1924, that he might consider completing his
unfinished novel “Suspense” ‘. The source for Miller’s quote is the ‘Richard Lancelyn Green
Archive, City of Portsmouth. The two writers were familiar with each other’s works obviously,
but there’s room to find out more about Conrad’s reading of Doyle.
