n the hall, and without a moment's hesitation they all followed.
The Professor led the way down a narrow and concealed path, but when they
reached the little clearing in which the hut was situated, they were
unable to approach any nearer. The place was a whirlwind of flame. The
smell of kerosene was almost overpowering. The wild yell of the leopard
rose above the strange, half-human gibbering of the monkeys and the
hoarse, bass calling of another voice, at the sound of which Lenora and
even Quest shuddered. Then, as they came, breathless, to a standstill,
they saw a strange thing. One side of the hut fell in, and almost
immediately the leopard with a mighty spring, leapt from the place and ran
howling into the undergrowth. The monkeys followed but they came straight
for the Professor, wringing their hands. They fawned at his feet as though
trying to show him their scorched bodies. Then for a single moment they
saw the form of the ape-man as he struggled to follow the others. His
strength failed him, however. He fell backwards into the burning chasm.

The Professor bade them farewell, an hour later, on the steps of the
house. He seemed suddenly to have aged.

"You have done your best, Mr. Quest," he said, "but Fate has been too

foul jealousy which smeared the walls of that hut with kerosene and set a
light to it. The work of a lifetime, my dreams of scientific immortality,
have vanished in those flames."

He turned slowly away from them and re-entered the house. Quest and Lenora
made their way down the avenue and entered the automobile which was
waiting for them, almost in silence. The latter glanced towards his
companion as they drove off.

"Say, this has been a bit tough for you," he remarked. "I'll have to call
somewhere and get you a glass of wine."

She tried to smile but her strength was almost gone. They drove to a
restaurant and sat there for a some little time. Lenora soon recovered her
colour. She even had courage to speak of the events of the afternoon when
they re-entered the automobile.

"Mr. Quest," she murmured, "who do you suppose burned the hut down?"

"If I don't say Craig, I suppose you will," he remarked. "I wonder whether
Laura's had
