In order to achieve his goal, Falstaff had some of his most trusted men follow Wayne Enterprises' CEO, Lucius Fox. Falstaff soon offered Fox a position in his own company with the only condition that he would reveal secrets of Wayne Ent. and betray Bruce Wayne. After Fox's refusal, Falstaff took a more direct approach and kidnapped the daughter of Bruce Wayne's personal secretary, forcing the woman to feed him information about Wayne's financial activities. With this information, Falstaff managed to seize most of Wayne's assets, but when Bruce uncovered his scheme, Falstaff was confronted by Batman. However, during their confrontation, Talia killed Falstaff from behind, claiming that Falstaff had stolen from her father.
Later, Batman learned that Talia was actually sent to deal with Falstaff, who had served his purpose after stealing Wayne's assets and was no longer needed by Ra's, the mastermind behind it all.
