Liesl Vitzlipützli

Liesl is a major character in the Deptford Trilogy by Robertson Davies. She's a physically grotesque, but incredibly charismatic and intelligent woman, who manages Paul Dempster's a.ka. Magnus Eisengrim's magic show. She hires Dunstan Ramsay, the trilogy's main character to ghost-write Paul's autobiography.
Her name is derived from a minor devil in Goethe's Faust.
