El Cojo? "He who goes with a limp." Der Stelze, Clubfoot, had been the nickname of that other cripple, the man of might in that Imperial Germany which sank to destruction in the fire and smoke of the Hindenburg Line, whose ways lay in dark places, whom everybody feared but whom so few had ever seen.... If he could rise from his grave and seek me out on the island, then, indeed, might my imagination, like poor old Carstairs', people these darkling woods with hidden spies!

Sunk in my thoughts I had wandered on heedlessly, going ever deeper into the tangle of the forest. But now the undergrowth, growing thicker, barred my further progress and I came to an abrupt halt with the thick tendril of some creeping plant wound about my body. On it blossomed a gaudy flower with a heavy, musky scent. The touch of the creeper on my bare arm made me shrink.

It was as dark as pitch in that jungle-like forest. A phrase I had read somewhere about "opaque blackness" flashed into my mind. I realised I stood an extremely good chance of being lost, and cursed myself for a dreamy fool. Fortunately, I had the orientation of our camp—I had taken it that afternoon on the beach—and I knew that, by striking west, I should roughly hit Horseshoe Harbour where we had put ashore.

I took out my compass and opening the lid, bent over the luminous needle. I stood absolutely still to allow the pointer to swing to rest. Then, from the black depths of the forest all about me, a gentle droning fell upon my ear. I listened. No mistake was possible. It was undoubtedly a human voice. And it was softly humming, as a man might hum quietly to himself, to pass away the time. I listened again. The voice rose and fell, with now and then a break, but always on a muted note. Suddenly, I caught the melody, a melancholy, haunting refrain with a phrase, as in a folksong, that came again and again. And I felt the perspiration break out on my brow, my heart grow cold within me, as I recognised the air....

"Se murio, y sobre su cara
"Un panuelito le heche...."

It was the song of Black Pablo, the singer in the lane.

CHAPTER XII

I MEET AN OLD ACQUAINTANCE

I remained rooted to the spot. The droning chant went on. How far the singer was from me, it was impossible to estimate; for a voice carries far at night—he might be anything from twenty to a hundred yards away. There was nothing to do but retire;.... in that clammy, steamy darkness any idea of stalking a man was out of the questions.
