In the conclusion of the two-part story "Black Orchid," the Doctor (Peter Davison), mistaken for a champion cricket player, is invited to a fancy dress ball on the eve of an important test match. Alas, he is unable to enjoy the festivities thanks to the presence of a demented killer who has targeted the Doctor's companion, Nyssa (Sarah Sutton), as his next victim. Written by Terence Dudley, "Black Orchid, Episode 2" was first telecast on March 2, 1982. ~ Hal Erickson, Rovi
