This was all the evidence obtainable, and the coroner now proceeded to
sum up.
The case, he said, was a most remarkable one, and it would be necessary
for the jury to consider very gravely all the evidence laid before them
in order to arrive at a proper conclusion before giving their verdict.
In the first place, it had been clearly proved by the Government analyst
that the deceased had died from effects of conia, which was, as they had
been told, the alkaloid of hemlock, a well-known hedge plant which grows
abundantly in most parts of Great Britain. According to the evidence of
Dr Chinston, the deceased had died from serous apoplexy, and from all
the post-mortem appearances this was the case. But they must remember
that it was almost impossible to detect certain vegetable poisons, such
as aconite and atropia, without minute chemical analysis. They would
remember a case which startled London some years ago, in which the
poisoner had poisoned his brother-in-law by means of aconite, and it
taxed all the ingenuity and cleverness of experts to find the traces of
poison in the stomach of the deceased. In this case, however, thanks to
Dr Gollipeck, who had seen the similarity of the symptoms between the
post-mortem appearance of the stomach of Adele Blondet and the present
case, the usual tests for conia were applied, and as they had been told
by the Government analyst, the result was conia was found. So they could
be quite certain that the deceased had died of poison--that poison
being conia. The next thing for them to consider was how the poison was
administered. According to the evidence of Miss Marchurst, some unknown
person had been standing outside the window and poured the poison into
the glass on the table. Mrs Villiers had stated that the window was open
all night, and from the position of the table near it--nothing would
be easier than for anyone to introduce the poison into the glass as
asserted by Miss Marchurst. On the other hand, the evidence of the
detective Kilsip went to show that no marks were visible as to anyone
having been at the window; and another thing which rendered Miss
Marchurst’s story doubtful was the resemblance it had to a drama in
which she had frequently acted, called ‘The Hidden Hand’. In the last
act of that drama poison was administered to one of the characters
in precisely the same manner, and though of course such a thing might
happen in real life, still in this case it was a highly suspicious
circumstance that a woman like Miss Marchurst, who had frequently acted
in the drama, should see the same thing actually occur off the stage.
Rejecting, then, as improbable the story of the hidden hand, seeing that
the evidence was strongly against it, the next thing was to look into
Miss Marchurst’s past life and see if she had any motive for committing
the crime. Before doing so, however, he would point out to them that
Miss Marchurst was the only person in the room when the crime was
committed.
