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 Château 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—an old servant in the Stangerson family. Daddy Jacques entered ‘The Yellow 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 château.
