Then his whereabouts were known only to himself, in the obscurity of a pitch-black room, the sanctum of The Shadow.
A LIGHT clicked, under the touch of an unseen hand. The rays of a hanging lamp spread themselves upon the surface of a polished table. Two long, slender hands came into view beneath the lamp.
They were white hands, adorned with a solitary ring that bore a strange gem. From the depths of a perfect fire opal glowed mysterious, shimmering colors, that changed from crimson to purple.
This was The Shadow’s only jewel — a girasol. Collectors of rare gems would have coveted that stone.
The hands were at work. Upon the table they spread a detail map of Manhattan, backed by a base of thick cardboard.
The fingers inserted glass-headed pins into the map. The pins indicated important spots.
One pin located the old house that had belonged to Theodore Galvin. Another showed the building in which Richard Harkness had died. Beside it, a third pin touched the spot where Acting Inspector Herbert Zull had been surprised by an attack in the dark.
These pins were placed rapidly in position. Now came new ones: a pin for the Cobalt Club, a pin for the Hotel Thermon. The fingers, bringing up new pins, set two markers side by side, one indicating the house where Moose Shargin had gone, the other the residence of Hiram Mallory, which stood adjacent.
A pin indicated the apartment hotel where Shargin and Elvers lived.
The fingers produced a white pin and placed it in a block far uptown. They produced a black pin and laid it on the map. That completed the preliminary work.
