Leturier in Montpellier, will occur at once to any toxicologist.

"And now came the great question as to the reason why.
Robbery had not been the object of the murder, for nothing
was taken. Was it politics, then, or was it a woman? That
was the question which confronted me. I was inclined from
the first to the latter supposition. Political assassins are
only too glad to do their work and to fly. This murder had,
on the contrary, been done most deliberately, and the
perpetrator had left his tracks all over the room, showing
that he had been there all the time. It must have been a
private wrong, and not a political one, which called for such
a methodical revenge. When the inscription was discovered
upon the wall I was more inclined than ever to my opinion.
The thing was too evidently a blind. When the ring was
found, however, it settled the question. Clearly the
murderer had used it to remind his victim of some dead or
absent woman. It was at this point that I asked Gregson
whether he had enquired in his telegram to Cleveland as
to any particular point in Mr. Drebber's former career.
He answered, you remember, in the negative.

"I then proceeded to make a careful examination of the room,
which confirmed me in my opinion as to the murderer's height,
and furnished me with the additional details as to the
Trichinopoly cigar and the length of his nails. I had
already come to the conclusion, since there were no signs of
a struggle, that the blood which covered the floor had burst
from the murderer's nose in his excitement. I could perceive
that the track of blood coincided with the track of his feet.
