Jessica (Angela Lansbury) and Seth (William Windom) are invited to the South Carolina plantation owned by Seth's cousin, a wealthy botanist. The visit becomes somewhat less than pleasant when the cousin turns up murdered. Evidently there are several people who would have benefited from this death, but the clues aren't quite so plentiful--but as always, Jessica needs only one or two clues to tighten the noose around the guilty party's neck. ~ Hal Erickson, All Movie Guide
