Vickers felt a strange sense of alarm as the boat left the yacht.

He noticed two or three suspicious circumstances.

As soon as they got away, he saw that all the yacht's lights had been or were being darkened or entirely obscured; at a dozen boat lengths they could see her no more.

Nor were there any lights on the shore itself; all there was in utter blackness.
