‘Here in Paris we know what is right.’ The Massacre (1966) is a serial of disputed authorship, of which no known video copy survives. One of the last of Doctor Who’s ‘past’ stories as originally defined, it was produced during a fractious transitional period. It nevertheless draws on a variety of primary and secondary sources, many never previously acknowledged, to examine religious civil strife in the Paris of 1572 from some surprising angles, and with maturity and complexity.
