Dim lights shone from the windows of the house on Death Island. Bars showed on those
same windows. The strange abode was one in which uninvited visitors could expect no
welcome. Curious people stayed away from the house on Death Island.
WITHIN the house was a room that contrasted oddly with the dull exterior. This was the front
room on the ground floor. It was the private study of Professor Arthur Whitburn, the old
inventor who owned the house on Death Island. Professor Whitburn's study was a cheery,
well-lighted room.
This room was in great disorder. A large bookcase ranged along one wall, and fully half of
its volumes had been removed. These missing books had not gone far. They were strewn
about the study. Stacks on the tables, stacks on the chairs, stacks on the floor; besides
these were other books, dropped at random, here and there.
In addition to the books, the floor and the furniture held mussed heaps of papers. Glass jars,
pieces of metal tubing, odd-looking mechanical contrivances added to the chaos. There
was a shelf in the corner where these articles belonged; it was a disorderly as the room.
Professor Whitburn had piled bottles and tubes haphazardly upon that shelf.
There was a desk near the center of the room. It was also a hodge-podge of books, papers,
and apparatus. The only object that appeared to be in its proper place was the telephone. It
stood at an angle, however, for it had been propped upon a crazy stack of handwritten
manuscripts.
A wide window sill was also well littered with papers; but this spot showed some semblance
of order. A large tiger-cat had chosen the sill for a resting place. Nestled there, the creature
looked over the room with an expression of part ownership. The cat seemed quite at home
in its select spot.
In fact, the cat was quite alert despite its assumed laziness. This was proven when the
animal rose and arched its back when it detected the sound of footsteps from the corridor
outside the study. Then, as the door opened, the cat nestled back on the window sill. It had
recognized the approach of its master.
PROFESSOR WHITBURN entered the study. Old, stooped and thin, he was a man of
curious appearance. His hair formed an untrimmed mass of white. His mustache —also
white—was long, with drooping ends. But the professor's eyes were keen. His sharp gaze
noted the cat settling back upon the window sill.
"Hello, Quex," chuckled the professor, approaching to stroke the cat. "What is the trouble?
Has something disturbed you?"
The cat responded with a plaintive meow. The old man studied the animal closely. Quex
blinked and emitted another meow. Then the cat subsided under the professor's friendly
strokes. While he quieted his pet, Whitburn stared about the room in suspicious fashion.
A glare appeared upon the old man's countenance. With sharp eyes, the professor surveyed
the stacks of books and heaps of papers. He moved away from the window sill and
approached the desk. He lifted the telephone and looked at the manuscript beneath it. He
picked up books and replaced them. Nodding, the old man turned toward the cat.
"You are right, Quex," declared Professor Whitburn. "Some one has been intruding here.
You know when matters are wrong, don't you, old fellow?"
Pausing, Whitburn again looked about the room. He muttered to himself, then spoke half
