“I have begun,” she said, “and I will go through with it. Besides, what danger could there be? People don’t go shooting and killing promiscuously like that.”

“Oh, don’t they!” Carpentaria exclaimed.

“Moreover, I have no fancy to be left alone here now,” she added. “And most likely there isn’t anyone there at all.”

“Hush!” said Carpentaria. “Can’t you hear the splash of an oar? Listen!”

They listened.

“Yes,” she murmured. “And is not that the noise of a boat crunching on the beach?”

The path disappeared mysteriously before them under the terrace; they could not see the end of it. But the sound-waves came clearly enough through the little tunnel.

“We will go back,” said Carpentaria, “and slip on to the terrace. Behind the parapet we can see anything that may happen to be going on. But quietly, quietly, dear lady.”

In a few moments they were creeping across the broad terrace. Simultaneously they bent down, side by side, under the parapet and looked between its squat, rounded pillars at the water below.

Pauline gave a slight smothered cry, which Carpentaria, with an imperious gesture, bade her check.
