Butterfly in Shades of Grey

Plot:

L.A. radio moderator Fielding Chase kills Gerry Winters, a member of his staff who tried to help Chase's daughter Victoria (also a staff member) to leave her father and become a novelist in New York. Chase presents a fine alibi: Winters was shot dead while speaking to him on the phone, even the shooting was recorded on his answering machine. Everything seems perfect, but will Lt. Columbo really believe this story?
