text_A: "SiP", as it is commonly known, began as a three-issue mini-series published by Antarctic Press in 1993, which focused entirely on the relationship between the three main characters and Francine's devoted boyfriend, to whom she is nonetheless unfaithful. This is now known as "Volume 1.” Thirteen issues were published under Moore's own "Abstract Studio" imprint, and these make up "Volume 2.” This is where the "thriller" plot was introduced. The series moved to Image Comics' Homage imprint for the start of "Volume 3,” but after eight issues moved back to Abstract Studio, where it continued with the same numbering. Volume 3 concluded at issue #90, released June 6, 2007.
text_B: Given the limited information about this series, is it possible that Francine herself was also having intimate relations with one of the other main characters?
YES.
