House at 4 rue Vauborel is both a home and a clandestine communications site in occupied Saint-Malo. Etienne LeBlanc and Marie-Laure LeBlanc live there under the pressure of German surveillance, and its ordinary features—stairs, a wardrobe, a chimney, and a front gate—are adapted for warning, concealment, and transmission. The house’s transformation makes domestic space part of the resistance, but also makes it a place where discovery can arrive at any moment.

Setting and Occupants

The house is identified in the occupation authorities’ required door list as the residence of Etienne LeBlanc, aged sixty-two, and Mademoiselle Marie-Laure LeBlanc, aged fifteen. That official record turns their home into a publicly legible address even as they use it to shelter secret activity. The contrast is central to the house’s role: its occupants must appear within the administrative order while hiding what they do inside it.

From the street, the building is tall and narrow, with eleven windows on its facade. Its foundation is furred with moss, and orange lichen marks the exterior. The house stands high on the edge of the sea, a position that gives its attic a strong location for broadcasting. Yet the antenna, when raised alongside the chimney, is almost invisible from street level. The building’s height and exposed situation therefore serve two purposes at once: they make it a useful transmitting point and a conspicuous object for anyone who knows what to look for.

Domestic Space Adapted for Secrecy

Before using the transmitter, Etienne LeBlanc makes the house more responsive to intrusion. He runs wires behind the walls to connect bells on the third floor, beneath the telephone table, in the attic, and at the front gate. Marie-Laure LeBlanc tests the arrangement by opening the outer gate from the street; from deep inside the house, two faint rings sound. The alarm system turns movement at the threshold into a warning that can travel through the building without announcing itself outside.

Etienne LeBlanc also builds a false back into a wardrobe, fitting it on a sliding track so that it can open from either side. The concealed compartment gives the house an interior boundary between what can be seen and what can be hidden. These alterations are practical rather than grand: wires, bells, and a modified piece of furniture become safeguards for the people and equipment within. The house is prepared not as a fortress, but as a home whose ordinary fittings have acquired a second, secret use.

At dusk, after the hidden mechanisms are installed, Etienne LeBlanc leads Marie-Laure LeBlanc upstairs, through the sixth-floor room, and up a ladder into the attic. He raises the heavy telescoping antenna beside the chimney and switches on the apparatus; a delicate crackle fills the attic. This is the house’s passage from concealed preparation to active transmission. The attic, tucked above the rooms of daily life, becomes the point from which a signal can leave the building.

A Resistance Address Under Pressure

The secrecy maintained inside the house is never secure. When its electric bell rings, Etienne LeBlanc, Madame Manec, and Marie-Laure LeBlanc stop chewing at the same moment, each fearing that their activities have been discovered. Their alarm encompasses the attic transmitter, the women in the kitchen, and the repeated journeys to the beach. The moment shows how separate elements of clandestine life converge at one address: a bell at the door can threaten not only the equipment upstairs but the whole network of people and movements connected to the household.

Messages also reach the house through an apparently ordinary exchange. In the summer of 1943, Madame Ruelle passes Marie-Laure LeBlanc a folded piece of paper beneath a loaf at the bakery. Marie-Laure takes the loaf home, secures the door, and waits for Etienne LeBlanc to come downstairs. Later, after an attack on a German truck in a village far to the south, Madame Ruelle brings another loaf containing nine numbers. The attack leads occupation authorities to intensify labor demands and restrictions around the coast, while the women warn that the authorities are blaming an elaborate network of anti-occupation radio broadcasts. The house is thus connected to a message route whose simplest covering is bread, even as the risks around communication increase.

The House Discovered

The same chimney that conceals the transmitter also gives Werner Pfennig a clue. At night, while searching the streets for a broadcasting source, he sees an antenna rise beside a chimney and unfold into a T. He locates it at a high house by the sea, notes how nearly invisible the antenna is from street level, and identifies the facade by its eleven windows, orange lichen, and mossy foundation. The address he recognizes is House at 4 rue Vauborel. The careful disguise has worked from below, but the antenna’s movement exposes the house to a trained observer.

During the bombardment, Marie-Laure LeBlanc reaches for the transmitter and uses the lever her uncle installed beside the chimney to extend the antenna. She hopes someone might still have a radio—perhaps the fire brigade, the resistance, or the Americans—and imagines that Etienne LeBlanc may be able to hear a sign of hope. The mechanism she activates was designed for communication, but in the damaged city its operation is also perilous: the antenna makes a grating noise above the roof, too loud for concealment. House at 4 rue Vauborel’s final significance lies in this unresolved tension. Its hidden architecture enables warnings and broadcasts, yet every opening, signal, and sound can disclose the people it was built to protect.
