On the line was Secretary Canitrot at the Brigade Criminelle. Without relaying the details of the discovery at rue Le Sueur, Canitrot urged the boss to come as quickly as possible and sent over a car right away. Fifteen minutes later, a long black Citroën 11 CV was waiting outside Massu's residence, the chauffeur with a hand at his cap.

Bernard wanted to tag along, as he sometimes did on the most serious or interesting cases. The commissaire agreed. Massu, a stocky man in his fifty-fifth year, with a shock of black hair and a dark mustache, put on his black overcoat and gray fedora. The two Massus, each wrapped up for the night chill, hopped into the car and drove across the city that, years before, would have been swirling with activity. That evening, however, Paris looked, as Massu put it, "somber and deserted."

The city was suffering the fourth year of the Nazi Occupation. Huge red and white banners emblazoned with a black swastika had flown atop the Eiffel Tower, the Arc de Triomphe, and many other landmarks and buildings near Petiot's town house. White placards with Gothic script directed traffic, mostly German and many of them, in that area, Mercedes-Benzes or Citroëns with small swastika flags on the fenders. The few people on the streets after the official ten p.m. curfew were Germans, "friends of the occupiers," and the "workers of the night." A brothel exclusively for Nazi officers was located just around the corner from Petiot's property.

As the car pulled up to 21 rue Le Sueur, a single streetlamp, hooded for the wartime blackout, cast a dim bluish light on the activities of the police, which, as Massu already realized, were inspiring an "uneasy curiosity" among the street's residents. Some officers controlled the crowd eager to watch from balcony windows; others followed the commissaire inside the town house. Policemen were now arriving every few minutes. Massu entered the mansion, which had a grand salon, a petit salon, a large formal dining room, a billiards room, a library, six bedrooms, and two kitchens. The house had previously belonged to Princess Marie Colloredo-Mansfeld, a sixty-seven-year-old Frenchwoman whose husband's family had borne the title of imperial prince since 1763. The French actress Cécile Sorel, the comtesse de Ségur and doyenne of the Comédie Française, had lived there in the 1930s, a neighboring concierge was telling people. This would be claimed for years, but it is not accurate. Sorel had only rented the house to store her extensive wardrobe and trunks of memorabilia from her long career on the stage.

The current owner of the property was far less known to the general public than either the princess or the actress. "The name Marcel Petiot meant absolutely nothing to me," Commissaire Massu admitted. It was the first time he had even heard it.

From what Massu could tell, the owner was an assiduous collector of fine art. Many of the rooms boasted a splendid array of crystal chandeliers, oriental rugs, antique furniture, marble statues, Sèvres vases, and oil paintings in gilded frames. At the same time, there was a startling state of neglect. The rooms were not only dusty and full of cobwebs, but also, in some cases, the furniture was turned over or stacked in corners as if at a flea market. In several rooms and corridors were torn wallpaper, loose baseboards, and dangling panels. Massu saw exquisite Louis XV furniture alongside filthy couches with visibly protruding springs. When one officer warned that the case would most likely turn out to be appalling, Massu was unfazed. He had heard this before. In fact, almost every time a new crime was discovered, someone usually noted that it would be a "terrible histoire." He had no doubt that this might well be the case. As chief of the Brigade Criminelle, he was used to investigating disturbing affairs.

Still Massu was taken aback at the macabre spectacle in the basement of 21 rue Le Sueur: the half-burned skull in the furnace, the pile of tibias, femurs, and other bones on the floor. A foot, Massu saw, was "blackened like a log that had been slowly consumed." A dismembered hand, curled up tightly, "grasped the thin air in desperation." A woman's torso lay there, with the flesh "gnawed away to reveal the splinters of the ribcage." The stench - "the sinister odor of roasted human flesh," as he put it - gripped his throat.
