Julia’s boss at the magazine Seine Scenes. Originally from New York City, Joshua is exacting and intense. Joshua gives Julia the assignment to write about the Vel’ d’Hiv’ roundup. When Julia’s article is eventually published, Joshua commends her on the attention the article gets but also points out that Julia neglected to interview any of the French policemen or bus drivers that participated in the roundup. Although he is confused and annoyed by Julia’s focus on the Vel’ d’Hiv’ children, Joshua ultimately agrees to give Julia an advance on her paycheck, which allows her to take Zoë to Italy in search of William.
