In the spring of 1924, the Andalucía Express departs Madrid for an overnight journey towards Seville. Near the rear of the train, two armed postal clerks guard a locked mail van containing a leather case said to be worth nearly a million pesetas.

When the emergency cord is pulled in open country, the van is found bolted from within. One clerk lies dead, the other gravely wounded, and the valuable case has vanished. A passenger has disappeared, his glove lies beside the bodies, and an injured railway inspector claims that a mysterious man jumped from the moving train.

But the evidence soon becomes stranger. A warning appears on the outside of a rain-soaked window. A photograph is taken from beyond the moving train. The dead clerk’s body disappears from a sealed carriage—and the missing leather case returns in its place.

With every clue apparently identifying a different culprit, the investigation must determine who was truly aboard the Andalucía Express, who was already dead before it departed, and how a living man vanished from a railway van locked on both sides.

This is a fast-moving Nocturnal Tales railway mystery of false identities, manufactured evidence and murder aboard one of Spain’s great night trains.

ℹ️ FOR LISTENERS
This is a complete original mystery written for Nocturnal Tales. The story is followed by a historical epilogue examining the real 1924 Andalucía Express murders that inspired it.
