man who robbed Mme. Van den Rosen and Princess Sonia
Danidoff are one and the same person.

"That is shown beyond dispute by tests made in the two cases with a
Bertillon dynamometer, an instrument of the nicest exactitude, which
proved that the same individual operated in both cases; that is one
point made good. And next, the man who robbed Mme. Van den Rosen and
Princess Sonia is Gurn. That is proved to equal demonstration by the
fact that the burglar burned his hand while engaged upon his crime, and
that Gurn has a scar on his hand which betrays him as the criminal; the
scar is faint now perhaps, but I can testify that it was very obvious at
the time of a disturbance which occurred at a low cafe named the
Saint-Anthony's Pig, where, accompanied by detective Lemaroy, who is
still in hospital for treatment for injuries received on that occasion,
I attempted, and failed, to arrest this man Gurn.

"Thus, gentlemen, I prove that the Langrune and Danidoff cases are the
work of but one man, and that man, Gurn.

"I come to another point. As you know, the murder of the Marquise de
Langrune was attended by some strange circumstances. At the inquest it
was proved that the murderer most probably got into the house from
outside, opening the front door with a skeleton key, and that he
obtained admission into the bedroom of the Marquise, not by burglarious
means--I lay insistence upon that--but by the simple means of her having
opened the door to him, which she did on the strength of his name, and,
finally, that if robbery was the motive of the crime, the nature of the
robbery remained a mystery.

"Now I have ascertained, gentlemen, and--if, as I shall ask you
presently, you decide to have an adjournment and a supplementary
investigation--I shall be able to prove two important facts. The first
is that the Marquise had in her possession a lottery ticket which had
just won a large first prize; this ticket had been sent to her by M.
Etienne Rambert. This ticket was not found at the time, but it was
subsequently traced to a person, who for the moment has utterly
disappeared, who declared that it was given to him by M. Etienne
Rambert. And it is further noteworthy that M. Etienne Rambert seemed to
be in greater funds from that time. The second fact I have ascertained
is that, although M. Etienne Rambert pretended to get into a first-class
carriage of a slow train at the gare d'Orsay, he most certainly was not
in that train between Vi
