from the apathy of sorrow in which I was sunken.

"Tell the cab feller to drive to the north side of Wandsworth Common,"
said a woman's voice--a voice speaking in broken English, a voice
which electrified me, had me alert and watchful in a moment.

I turned, as the speaker, entering a taxi-cab that was drawn up by the
pavement, gave these directions to the door-porter, who with open
umbrella was in attendance. Just one glimpse I had of her as she
stepped into the cab, but it was sufficient. Indeed, the voice had
been sufficient; but that sinuous shape and that lithe swaying movement
of the hips removed all doubt.

It was Zarmi!

As the cab moved off I ran out into the middle of the road, where
there was a rank, and sprang into the first taxi waiting there.

"Follow the cab ahead!" I cried to the man, my voice quivering with
excitement. "Look! you can see the number! There can be no mistake. But
don't lose it for your life! It's worth a sovereign to you!"

The man, warming to my mood, cranked his engine rapidly and sprang to

Eternally I was peering ahead; and when, leaving the well-lighted West

suburbs, a hundred times I thought we had lost the track. But always
in the pool of light cast by some friendly lamp, I would see the
quarry again speeding on before us.

At a lonely spot bordering the common the vehicle which contained
Zarmi stopped. I snatched up the speaking-tube.

"Drive on," I cried, "and pull up somewhere beyond! Not too far!"

The man obeyed, and presently I found myself standing in what was now
become a steady downpour, looking back at the headlights of the other
cab. I gave the driver his promised reward.

"Wait for ten minutes," I directed; "then if I have not returned, you
need wait no longer."

I strode along the muddy, unpaved path, to the spot where the cab, now
discharged, was being slowly backed away into the road. The figure of
Zarmi, unmistakable by reason of the lithe carriage, was crossing in
the direction of a
