He was secretive in his methods, using contacts which were unknown to his companions on the force. It was Zull’s boast that he could lay a snare for any man who crossed him.

He had met such a man tonight — The Shadow. They would meet again!

“Lying low,” muttered Zull, contemptuously, “that’s what he’s doing now! Pulled one on me when he got away. Nervy bird — The Shadow — except when he gets cold feet.

“Well, I’ll be ready for him. He’ll be back on my trail if he’s as clever as he’s supposed to be — and I’ll lead him everywhere — except where he wants to go!”

When Zull reached headquarters, he found a stack of reports awaiting him. He studied the statements made by Lester, by the housekeeper, and by others who had known Richard Harkness.

While he was thus engaged, his mind reverted to The Shadow. When he thought of that mysterious man, Zull pictured him hiding away in some dark room.

STRANGELY enough, Zull’s conjecture was not entirely wrong. At that very moment, The Shadow was immersed in the darkness of a room not many blocks from the house where the body of Richard Harkness lay.

But The Shadow was not there from fear. He, too, had work to do. As Zull began to inspect the reports more closely, The Shadow began an examination of his own.

There was a click in the dark room where The Shadow was wont to go alone. A low-hanging light threw its rays upon the surface of a polished table.

Two hands appeared there. They were long, slender hands; white hands, with tapering fingers. Upon the left hand glowed a peculiar gem — a rare fire opal that caught the rays of the light and reflected them from crimson depths.
