Jacques Dollon, supported by two people, descended and entered the cab.
Immediately a rumour spread that he had been arrested.
This rumour was correct.
Our Inquiry—Silence at Police Headquarters—Probable Motives of the Crime
Such are the details referring to this strange affair, which we have been able to procure from those who were present. But the motives which determined the arrest of Monsieur Dollon are obscure.
There are, however, two suspicious facts. The first is the puncture made in Monsieur Jacques Dollon's left leg: this puncture is aggravated by a scratch. According to the doctors, soporific, injected into the human body by the de Pravaz syringe, acts violently and efficaciously. It is beyond a doubt that Monsieur Jacques Dollon has been rendered unconscious in this manner.
To begin with, the painter's first version was considered the true one, namely, that he had been surprised by robbers, who rendered him unconscious; but, on reflection, this explanation would not hold water. Murderous house-thieves do not send people to sleep: they kill them. Add to this that nothing has been stolen from Monsieur Dollon: therefore, mere robbery was not the motive of the crime.
Besides, Monsieur Dollon maintained that he was alone; yet at that time Madame de Vibray was in his studio, and was there precisely because the artist himself had asked her to come. We know that the Baroness de Vibray, who was very wealthy, took a particular interest in this young man and his sister.

Thus the assassination of the Marquise de Langrune cannot have been forgotten, an assassination which has remained a mystery, which was perpetrated a few years ago, and brought into prominence the personalities of Monsieur Rambert and the charming Thérèse Auvernois....
