Thirteen at Dinner

When actress Jane Wilkinson (Faye Dunaway) forcefully demands a divorce from her husband, she appears unstable. Consequently, she is the main suspect when her husband turns up murdered. Master Detective Hercule Poirot (Peter Ustinov), who meets the actress through actor Bryan Martin (Lee Horsley), must determine, along with Inspector Japp (David Suchet), if Wilkinson's claims of innocence are true, and whether Carlotta Adams (also Dunaway), a Wilkinson impersonator, is involved.
