It was hard to know which way to turn. Every path was choked with tangled weeds and bushes. Here and there remained one or two wonderful old trees, but the vegetation for the greater part consisted of laurel and other shrubs, which from lack of attention had grown almost into a jungle. They wandered about almost aimlessly for nearly half-an-hour. Then Quest came to a sudden standstill. Lenora gripped his arm. They had both heard the same sound—a queer, crooning little cry, half plaintive, half angry. Quest looked over his right shoulder along a narrow, overgrown path which seemed to end abruptly in an evergreen hedge.

“What’s that?” he exclaimed.

Lenora still clung to his arm.

“I hate this place,” she whispered. “It terrifies me. What are we looking for, Mr. Quest?”

“Can’t say that I know exactly,” the latter answered, “but I guess we’ll find out where that cry came from. Sounded to me uncommonly like a human effort.”

They made their way up as far as the hedge, which they skirted for a few yards until they found an opening. Then Quest gave vent to a little exclamation. Immediately in front of them was a small hut, built apparently of sticks and bamboos, with a stronger framework behind. The sloping roof was grass-grown and entwined with rushes. The only apology for a window was a queer little hole set quite close to the roof.

“The sort of place where the Professor might keep some of his pets,” Quest observed thoughtfully. “We’ll have a look inside, any way.”

There was a rude-looking door, but Quest, on trying it, found it locked. They walked around the place but found no other opening. All the time from inside they could hear queer, scuffling sounds. Lenora’s cheeks grew paler.

“Must we stay?” she murmured. “I don’t think I want to see what’s inside. Mr. Quest! Mr. Quest!”

She clung to his arm. They were opposite the little aperture which served as a window, and at that moment it suddenly framed the face of a creature, human in features, diabolical in expression. Long hair drooped over one cheek, the close-set eyes were filled with fury, the white teeth gleamed menacingly. Quest felt in his pocket for his revolver.
