The bridge was artificial, so was the stream’s present course. It had been diverted from the natural channel that marked the path to the transverse. Letting his eye rove up the stream, Cranston saw where it came from.
This rivulet had long ago been put underground. The bank which it flowed from rose high above it, forming a great mass of earth which was flanked by jutting rocks, high above.
Not as high as the Knoll, those rocks, though they were like small foothills leading toward it.
At the spot where the stream issued, there was a heavy iron grating set deep into a rock formation that formed the foundation of the grassy embankment. Cranston didn’t follow the stream, because his path lay off to the right of it. So he continued his stroll by that route until he reached the Graceland Memorial Library.
A polite attendant started to show Cranston to the room that contained old maps and volumes dealing with the history of early New York, but Cranston shook his head. There was another room that interested him more today. It bore a sign:
MANHATTAN GENEALOGY
It didn’t take Cranston long to find the volume that he wanted, since it was practically at the head of the row, among those bearing the letter A. In opening the book, Cranston practically skimmed through the early pages, proving that he was more interested in more modern data.
As he found what he wanted, Cranston gave a strangely subdued laugh, which by its very tone belonged to his other self, The Shadow!
CHAPTER XVI
IT was dusk when Lamont Cranston stopped around to see Craig Farnsworth. The evening was balmy so they went out on the high terrace that overlooked the park.
