 Hornung knew Doyle 's sister , Constance ( " Connie " ) <unk> Monica Doyle ( 1868 – 1924 ) , whom he had met when he visited Portugal . Connie was described by Doyle 's biographer , Andrew <unk> , as being attractive , " with pre @-@ <unk> looks ... the most sought @-@ after of the Doyle daughters " . By December 1892 , when Hornung , Doyle and Jerome visited the Black Museum at Scotland Yard , Hornung and Connie were engaged , and in 1893 Hornung dedicated his second novel , Tiny <unk> , " to <unk> " They were married on 27 September 1893 , although Doyle was not at the wedding and relations between the two writers were sometimes strained . The <unk> had a son , Arthur Oscar , in 1895 ; while his first name was from Doyle , who was also Arthur 's <unk> , the boy 's middle name was probably after Doyle and Hornung 's mutual friend Oscar Wilde and it was by his second name that he was known . In 1894 Doyle and Hornung began work on a play for Henry Irving , on the subject of boxing during the Regency ; Doyle was initially eager and paid Hornung £ 50 as a down payment before he withdrew after the first act had been written : the work was never completed .
