How would you explain “lines of charlie” in the context? “Tansy Bestigui definitely witnessed Landry falling past the window, though, didn’t she? Because Wilson reckons he heard the body fall right before Mrs. Bestigui started screaming.” “Maybe she saw it, but she wasn’t having a pee. She was doing a couple of lines of charlie in the bathroom. We found it there, cut and ready for her.” “Left some, had she?” “Yeah. Presumably the body falling past the window put her off.” How would you explain “lines of charlie” in the second passage? Thanks!
