diminished by reason of her elder brothers, and she
had scarcely enough to pay her debts; while the rebukes
were renewed from the mouths of her brothers, one
of whom, being civil lieutenant, had the power to
separate her again from her lover. This must
be prevented. Lachaussee left the service of
Sainte-Croix, and by a contrivance of the marquise
was installed three months later as servant of the
elder brother, who lived with the civil lieutenant.
The poison to be used on this occasion was not so
swift as the one taken by M. d’Aubray so violent
a death happening so soon in the same family might
arouse suspicion. Experiments were tried once
more, not on animals—for their different
organisation might put the poisoner’s science
in the wrong—but as before upon human subjects;
as before, a ‘corpus vili’ was taken.
The marquise had the reputation of a pious and charitable
lady; seldom did she fail to relieve the poor who
appealed: more than this, she took part in the
work of those devoted women who are pledged to the
service of the sick, and she walked the hospitals
and presented wine and other medicaments. No
one was surprised when she appeared in her ordinary
way at l’Hotel-Dieu. This time she brought
biscuits and cakes for the convalescent patients, her
gifts being, as usual, gratefully received. A
month later she paid another visit, and inquired after
certain patients in whom she was particularly interested:
since the last time she came they had suffered a relapse—the
malady had changed in nature, and had shown graver
symptoms. It was a kind of deadly fatigue, killing
them by a slows strange decay. She asked questions
of the doctors but could learn nothing: this malady
was unknown to them, and defied all the resources of
their art. A fortnight later she returned.
Some of the sick people were dead, others still alive,
but desperately ill; living skeletons, all that seemed
left of them was sight, speech, and breath.
At the end of two months they were all dead, and the
physicians had been as much at a loss over the post-mortems
as over the treatment of the dying.
Experiments of this kind were reassuring; so Lachaussee
had orders to carry out his instructions. One
day the civil lieutenant rang his bell, and Lachaussee,
who served the councillor, as we said before, came
up for orders. He found the lieutenant at work
with his secretary, Couste what he wanted was a glass
of wine and water. In a moment Lachaussee brought
it in. The lieutenant put the glass to his lips,
but at the first sip pushed it away, crying, “What
have you brought, you wretch? I believe you
want to poison me.” Then handing the glass
to his secretary, he added, “Look at it, Couste:
what is this stuff?” The secretary put a few
drops into a coffee-spoon, lifting it to his nose and
then to his mouth: the drink had the smell and
taste of vitriol. Meanwhile Lachaussee went
up to the secretary and told him he knew what it must
be: one of the councillor’s valets had
taken a dose of medicine that morning, and without
noticing he must have brought the very glass his companion
had used. Saying this, he took the glass from
the secretary’s hand, put it to his lips, pretending
to taste it himself, and then said he had no doubt
it was so, for he recognised the smell. He then
threw the wine into the fireplace.
