escription: it was
like a glimpse into another world where all petty struggles and troubles
had faded away. It needed an effort to leave the beautiful moonlight and
go to bed inside the tent, but they tore themselves away from it at
last, and rolled themselves up in their rugs. It was a long time before
either of them slept; the unusual circumstances, their cramped position,
and the swish-swash-grind of the waves made them keenly on the alert.
Though Lorraine would not have confessed it for worlds, she found the
situation a trifle eerie. She thought she heard noises in the distance,
and recalled tales of smugglers and wreckers and ghost-haunted coves.
She was glad to have Margaret close beside her. There was comfort in the
sense of contact with something human. Not till after midnight did she
fall into a troubled sleep.

When she awoke, the moon had passed across the sky, and the first hint
of dawn was in the air. Margaret had flung back her rug, and was
stepping out of the tent. Lorraine followed her, shivering a little, for
the morning air was chilly. Everything was wreathed in pearly shadows,
and the headland loomed like a grey mass of mist, with the sea for a
silver lake below. Each moment the light seemed to grow stronger, and
what at first had appeared mere clumps of darkness resolved themselves

rose. Margaret, whose paints were ready, began to set up her easel to
sketch the evanescent effect without delay. But just as she was putting
in the pegs, Lorraine nudged her and pointed. At the end of the cove,
where the bay merged into the open sea, there had suddenly arisen a
strange object. They both looked at it, and both at the same moment
realized what it was--neither more or less than the conning tower of a
U-boat!

Margaret hastily pulled down her easel, and drew Lorraine behind the
shelter of some rocks. She judged that if a U-boat were so near to the
coast, then somebody in collusion with the enemy must be about on the
shore. Nor was she mistaken. They had hardly concealed themselves when
voices were heard quite a short distance away, and the grating sound of
a boat being pushed along the shingle. In the gathering brightness of
the dawn they could see, not a hundred yards off, the entrance to a cave
from which two men were taking some barrels. They rolled them down the
