Darby was prosecuted for sexually abusing his 13-year-old stepdaughter, Wendy. Wendy testified to Darby's conduct. On cross-examination, defense counsel asks Wendy, "Isn't it true that shortly before you complained that Darby abused you, he punished you for maliciously ruining some of his phonograph records?" The question is 
proper, because it relates to a possible motive for Wendy to accuse Darby falsely.  proper, because Wendy's misconduct is relevant to her character for veracity.  improper, because the incident had nothing to do with Wendy's truthfulness.  improper, because it falls outside the scope of direct examination.
