Luciano soon became a top aide in Masseria's criminal organization. In contrast to Rothstein, Masseria was uneducated, with poor manners and limited managerial skills. By the late 1920s, Masseria's main rival was boss Salvatore Maranzano, who had come from Sicily to run the Castellammarese clan. Maranzano refused to pay commissions to Masseria. Their rivalry eventually escalated into the bloody Castellammarese War and ultimately resulted in the deaths of both Maranzano and Masseria.
At Sherborne, Turing formed a significant friendship with fellow pupil Christopher Morcom (1911 – 1930), who has been described as Turing's "first love". Their relationship provided inspiration in Turing's future endeavours, but it was cut short by Morcom's death, in February 1930, from complications of bovine tuberculosis, contracted after drinking infected cow's milk some years previously.
