In this episode of the Explaining History Podcast, we're joined by writer Susan Barrett to discuss her new novel, *All Cats Are Grey*—a dark and compelling work of historical fiction set against the backdrop of the London Blitz.

The book tells the story of four very different people, each of whom has committed what might be called a "necessary murder" in their past. They come together during the chaos of the blackout to use their lethal skills against a serial rapist and murderer who is exploiting the wartime disruption to terrorise the bomb-scarred streets of London. This villain is inspired by a real figure: Gordon Cummings, an infamous but largely forgotten serial killer of the Blitz era.

But our conversation ranges far beyond the plot. Susan, whose background is in film and television research, shares fascinating insights into how historical research has changed—and what we lose in the age of the internet. She discusses the serendipity of physical archives, the power of handwritten ledgers and Victorian photographs, and the surprising voices uncovered by the Mass Observation project that challenge our assumptions about "respectable" wartime behaviour.

We also delve into the mythology of the Blitz itself. How does the reality of crime, class division, and social disruption sit alongside the cherished national story of plucky unity? What did people actually think and do when the bombs were falling? And why does Britain have such a peculiar fascination with poisoners and serial killers?

From the tragic case of Timothy Evans and Reginald Christie to the Jack the Ripper industry, from the origins of the welfare state to the echoes of COVID—this is a wide-ranging conversation about history, memory, and the stories we tell ourselves.

*All Cats Are Grey* is published on 24th April by Bathwick Hill Press, a small independent publisher. Please consider supporting independent bookshops and publishers.
