Dark Footnotes

In 1910, a wireless message from a steamship crossing the Atlantic helped launch an extraordinary manhunt. But the pursuit of Hawley Harvey Crippen began with something more personal: the disappearance of his wife, Cora, known to friends as Belle Elmore.

From the house at 39 Hilldrop Crescent to the Old Bailey, this episode follows a missing-person investigation, disputed forensic findings, a dramatic arrest at sea, and the judicial decisions that followed. Nearly a century later, analysis of a preserved tissue sample raised new questions about evidence central to the case.

What did the jury decide? What can later science actually establish? And what remains unknown about Cora?

Madrid, 1888. Luciana Borcino is found murdered in an apartment on Calle de Fuencarral.

What begins as a criminal investigation becomes a national controversy. Conflicting accounts, accusations of influence, and intense newspaper coverage turn a single murder into a wider debate about justice and public opinion.

In the first episode of Dark Footnotes, we revisit the Fuencarral case, examining the evidence, the trial, the verdict, and the questions that remain.

Some crimes leave more than a mystery. They leave a mark on history.

Content note: This episode discusses a historical murder, a criminal trial, and an execution.
