Killer By Night (1972)

A doctor (Robert Wagner) races against time after a woman dies in a hospital emergency room of Diphtheria, a highly communicable disease, to find others who were in contact with her before the disease spreads. Meanwhile, a police captain (Greg Morris) is searching for a cop killer (Robert Lansing) on the loose. Could the two cases be connected? Directed by Bernard McEveety (NAPOLEON AND SAMANTHA). A surprisingly effective thriller for most of its running time until the movie's last unfortunate 15 minutes when it fizzles out. Of course, better movies have been made with the same situation (PANIC IN THE STREETS comes to mind) but director McEveety keeps squeezing the tension quotient. With Diane Baker, Mercedes McCambridge (very good as a blind nun who cracks the case), Theodore Bikel and Nora Marlowe.
