A popular member of the Oxford community is killed, and nobody can think why, so a police inspector is called in from Scotland Yard, and discovers they may be more to the victim than met anyone's eye. 'Who Killed Lamb?' is a one off play from Yorkshire TV which has no connection with Thriller but was transmitted immediately after 'Sign It Death' in the second series schedule and was billed and fully networked as an episode of the classic ATV series. An American actor is featured, along with scripted Americanisms like "janitor" While it bears a similar running time [65 minutes], it uses a standalone title scene and theme music. This was quite a prestigious and well-received production at the time.
