Beautrelet discovers that the Étretat Needle is hollow, a secret sanctuary and treasure vault used by kings and now by Arsène Lupin. He locates the hidden entrance and observes Lupin's men moving goods out at night. He then meets Inspector Ganimard, who reveals that the government considers the Needle a state secret of military importance. They plan an assault for the next day at high tide, using a dozen fishing smacks and a torpedo boat to block escape by sea.

## Key lines

> The Étretat Needle was hollow! Was it a natural phenomenon, an excavation produced by internal cataclysms or by the imperceptible action of the rushing sea and the soaking rain? Or was it a superhuman work executed by human beings, Gauls, Celts, prehistoric men?

Beautrelet realizes that the Needle at Étretat is hollow, and wonders whether it was formed by nature or carved by ancient peoples.

_This marks the central revelation of the chapter, confirming the secret of the Hollow Needle._

> Without the Hollow Needle, Lupin is incomprehensible, a myth, a character in a novel, having no connection with reality.

The narrator argues that Lupin's extraordinary success is only possible because of the hidden fortress, without which he would seem like a fictional character.

_This emphasizes the importance of the secret location to Lupin's legend and operations._

> Beautrelet, I was at the Élysée last night. They look upon this matter as a state secret of the utmost gravity. There are serious reasons for concealing the existence of this citadel—reasons of military strategy, in particular.

Ganimard tells Beautrelet that the government considers the Needle a top-secret military asset, potentially useful as an arsenal for new explosives.

_This reveals the political and strategic stakes beyond Lupin's criminal activities._
