In “The Nose Knows” Betty displays another talent—recognizing smells—and Veronica leads her around the school getting her to identify locations such as the staff room (coffee) or the art class (linseed oil). Then they go by the school library.
This would never happen. If the books in the library are in such a bad state that the smell of mold lingers in the hallway then Riverdale High has a serious problem and the health inspector would get involved.
“The Nose Knows” was written by Kathleen Webb, pencilled by Jeff Schultz, inked by Henry Scarpelli and lettered by Bill Yoshida. It first appeared in Betty and Veronica 180 (December 2002). No colourist is given but I think a different reprint gives it as Barry Grossman. I saw it in Betty and Veronica (Jumbo Comics) Double Digest 276 (October 2019). It is copyright Archie Comic Publications.
