1892, the following note appeared in the latest edition of the "Temps":

"A frightful crime has been committed at the Glandier, on the border of the forest of Sainte-Genevieve, above Epinay-sur-Orge, at the house of Professor Stangerson. On that night, while the master was working in his laboratory, an attempt was made to assassinate Mademoiselle Stangerson, who was sleeping in a chamber adjoining this laboratory. The doctors do not answer for the life of Mdlle. Stangerson."

The impression made on Paris by this news may be easily imagined. Already, at that time, the learned world was deeply interested in the labours of Professor Stangerson and his daughter. These labours - the first that were attempted in radiography - served to open the way for Monsieur and Madame Curie to the discovery of radium. It was expected the Professor would shortly read to the Academy of Sciences a sensational paper on his new theory, - the Dissociation of Matter, - a theory destined to overthrow from its base the whole of official science, which based itself on the principle of the Conservation of Energy. On the following day, the newspapers were full of the tragedy. The "Matin," among others, published the following article, entitled: "A Supernatural Crime":

"These are the only details," wrote the anonymous writer in the "Matin" - "we have been able to obtain concerning the crime of the Chateau du Glandier. The state of despair in which Professor Stangerson is plunged, and the impossibility of getting any information from the lips of the victim, have rendered our investigations and those of justice so difficult that, at present, we cannot form the least idea of what has passed in The Yellow Room in which Mdlle. Stangerson, in her night-dress, was found lying on the floor in the agonies of death. We have, at least, been able to interview Daddy Jacques - as he is called in the country - a old servant in the Stangerson family. Daddy Jacques entered The Room at the same time as the Professor. This chamber adjoins the laboratory. Laboratory and Yellow Room are in a pavilion at the end of the park, about three hundred metres (a thousand feet) from the chateau.

"'It was half-past twelve at night,' this honest old man told us, 'and I was in the laboratory, where Monsieur Stangerson was still working, when the thing happened. I had been cleaning and putting instruments in order all the evening and was waiting for Monsieur Stangerson to go to bed. Mademoiselle Stangerson had worked with her father up to midnight; when the twelve strokes of midnight had sounded by the cuckoo-clock in the laboratory, she rose, kissed Monsieur Stangerson and bade him good-night. To me she said "bon soir, Daddy Jacques" as she passed into The Yellow Room. We heard her lock the door and shoot the bolt, so that I could not help laughing, and said to Monsieur: "There's Mademoiselle double-locking herself in, - she must be afraid of the 'Bete du bon Dieu!'"
