"You smoked a cigarette there. Where did you put the end?"

Van Sneck rose and went into the conservatory. He walked directly to a large pot of stephanotis in a distant corner and picked the stump of a gold-tipped cigarette from thence.

"I dropped it in there," he said. "Strange; if you had asked me that question two minutes ago I should not have been able to answer it. And now I distinctly remember pitching it in there and watching it scorch some of that beautiful lace-like moss. There is a long trail of it hanging down behind. I recollect how funnily it occurred to me, even in the midst of my danger, that the trail would look better brought over the front of the pot. Thus."

He lifted the long, graceful spiral and brought it forward. Steel nodded, approvingly.

"I came very near to dropping the ring in there," Van Sneck explained. "I had it in my fingers—I took it for the purpose from my waistcoat-pocket. Then I saw Henson's eye on me and I changed my mind. I wish I had been more sober."

Bell was examining a pot a little lower down. A piece had been chipped off, leaving a sharp, clean, red edge with a tiny tip of hair upon it.

"You fell here," he exclaimed. "Your head struck the pot. Here is a fragment of your hair on it. It is human hair beyond a doubt, and the shade matches to a nicety. After that—"

A sudden cry broke from the Dutchman.

"I've got it!" he exclaimed. "You have cleverly led my mind into the right direction. The only marvel is that I did not think of it before. You will find the ring in the pot where the tuberose grows. I am quite certain you will find it amongst the moss at the base."

David carefully scooped up all the loose moss from the pot and laid it on the study table. Then he shook the stuff out, and something glittering lay on the table—a heavy ring of the most exquisite and cunning workmanship, with a large gem in the centre, flanked by black pearls on either side. Van Sneck took it in his fingers lovingly.
