Inclosed are articles required. Sample of paper used as stationery at Larchmont Court. Sample of paper found in Durgan’s apartment when I entered with the master key you sent me. Sample of tobacco found in cigarette box at Durgan’s.
The code used was the one which The Shadow had given to Cliff Marsland.
The hands found the articles mentioned within an inner envelope. They were placed on the table also.
Then the hands produced a strange machine that bore an odd resemblance to a stereopticon. It was a portable black-light apparatus — science’s latest weapon against crime. A wire ran from the machine. The hands disappeared.
There was a slight noise as the plug at the end of the wire was fitted into the wall of the room.
The Shadow was back at work. Beneath the circle of purplish rays that came from the strange machine, the hands set three tiny fragments of paper — two torn from the sheets sent by Cliff Marsland — the third the fragment that had been taken from the closet floor.
The slips of paper glowed with an eerie light. They seemed to be charged with luminous paint. One fragment had a darkish tinge. Two were a dull orange.
Above the rays of the detector, The Shadow held a microscope. The enlarged views of the orange-glowing fragments showed that they were identical.
The bit of paper found in the closet was the same as the sample that had come from Killer Durgan’s apartment!
Now the tobacco was subjected to the test. Here, again, there was a strange, oddly shimmering glow, that did not leave an iota of doubt. The same mixture of tobacco had been found in the closet and in Durgan’s cigarette box!
