ets of Cairo was
immediately forthcoming, and into it I sprang.

"Tell the man to follow the other carriage," I said to the porter, "as
fast as he can go."

The porter said something in Arabic to the driver, and a moment later we
were off in pursuit.

It was a beautiful night, and, after the heat of the day, the rush
through the cool air was infinitely refreshing. It was not until we had
gone upward of a mile, and the first excitement of the chase had a
little abated, that the folly of what I was doing came home to me, but
even then it did not induce me to turn back. Connected with Pharos as I
was, I was determined if possible to find out something more about him
and his doings before I permitted him to get a firmer hold upon me. If I
could only discover his business on this particular night, it struck me,
I might know how to deal with him. I accordingly pocketed my scruples,
and slipping my hand into my pocket to make sure that my revolver was
there, I permitted my driver to proceed upon his way unhindered. By this
time we had passed the Kasr-en-Nil barracks, and were rattling over the
great Nile bridge. It was plain from this that whatever the errand might
be that was taking him abroad, it at least had no connection with old
Cairo.

Crossing the Island of Bulak, and leaving the caravan depot on our left,
we headed away under the avenue of beautiful Lebbek-trees along the road
to Gizeh. At first I thought it must be the Museum he was aiming for,
but this idea was dispelled when we passed the great gates and turned
sharp to the right hand. Holding my watch to the carriage-lamp, I
discovered that it wanted only a few minutes to eleven o'clock.

Although still shaded with Lebbek-trees, the road no longer ran between
human habitations, but far away on the right and left a few twinkling
lights proclaimed the existence of Fellahin villages. Of foot-passengers
we saw none, and save the occasional note of a night-bird, the howling
of a dog in the far distance, and the rattle of our own wheels, scarcely
a sound was to be heard. Gradually the road, which was raised several
feet above the surrounding country, showed a tendency to ascend, and
just as I was beginning to wonder what sort of a Will-o'-the-wisp chase
it was upon which I was being led, and what the upshot of it would be,
it came to an abrupt standstill, and towering into the starlight above
me, I saw two things which swept away all my doubts, and told me, as
