 A number of theories have also been put forward to explain the derivation of Bunbury , and <unk> , which are used in the play to imply a secretive double life . It may have derived from Henry Shirley Bunbury , a <unk> acquaintance of Wilde 's youth . Another suggestion , put forward in 1913 by Aleister Crowley , who knew Wilde , was that Bunbury was a combination word : that Wilde had once taken train to <unk> , met a schoolboy there , and arranged a second secret meeting with him at Sunbury .
