Stuart unmolested. I credited
"Le Balafre" with sufficient acumen to distrust the genuineness of
my intoxication, even if he was unaware of my real identity. I never
make the mistake of underestimating an opponent's wit, and whilst
acting on the assumption that the scarred man knew me to be forcing
his hand, I recognized that whether he believed me to be drunk or
sober, Gaston Mas or another, his line of conduct must be the same.
He must take it for granted that I actually designed to lodge my notes
with Dr. Stuart and endeavour to prevent me doing so.

I could detect no evidence of surveillance whatever and cranking the
engine I mounted and drove off. More than once, as I passed along
Commercial Road, I stopped and looked back. But so far as I could
make out no one was following me. The greater part of my route lay
along populous thoroughfares, and of this I was not sorry; but I did
not relish the prospect of Thames Street, along which presently my
course led me.

Leaving the city behind me, I turned into that thoroughfare, which at
night is almost quite deserted, and there I pulled up. _Pardieu!_ I
was disappointed! It seemed as though my scheme had miscarried. It
could not understand why I had been permitted to go unmolested, and I
intended to walk back to the corner for a final survey before
continuing my journey. This survey was never made.

As I stopped the cab and prepared to descend, a faint--a very faint--

head, ripping its way through my cloth cap!

Yes! That movement had saved my life, for otherwise the knife must
have entered my shoulder--and pierced to my heart!

Someone was hidden in the cab!

He had quietly opened one of the front windows and had awaited a
suitable opportunity to stab me. Now, recognizing failure, he leapt
out on the near side as I lurched and stumbled from my seat, and ran
off like the wind. I never so much as glimpsed him.

"_Mon Dieu!_" I muttered, raising my hand to my head, from which blood
was trickling down my face, "the plan succeeds!"

I bound a handkerchief as tightly as possible around the wound in my
scalp and put my cap on to keep the bandage in place. The wound was
only a superficial one, and except for the bleeding I suffered no
inconvenience from it. But I had now a legitimate reason for visiting
Dr. Stuart, and as I drove on towa
