"I wonder whether I'll be in time?" he muttered to himself in German, going forward as he bent against the cold driving rain which swept in from the sea. He usually spoke German to himself when alone. His way, for the first mile, was beside a long straight "drain," into which, in the darkness, it would have been very easy to slip had he not now and then flashed on his lamp to reveal the path. Beneath his breath, in German, he cursed the weather, for already the bottoms of his trousers were saturated as he splashed on through the mud, while the rain beat full in his face. Presently he came in sight of a row of cottage-windows at a place called Langham, and then, turning due north into the marshes, he at last, after a further mile, came to the beach whereon the stormy waters of the North Sea were lashing themselves into a white foam discernible in the darkness. That six miles of low-lying coast, stretching from the little village of Chapel St Leonards north to Sutton-on-Sea, was very sparsely inhabited--a wide expanse of lonely fenland almost without a house. Upon that deserted, low-lying coast were two coastguard stations, one near Huttoft Bank and the other at Anderby Creek, and of course--it being war-time--constant vigil was kept at sea both night and day. But as the district was not a vulnerable one in Great Britain's defences, nothing very serious was ever reported from there to the Admiralty. By day a sleepy plain of brown and green marshes, by night a dark, cavernous wilderness, where the wild sea beat monotonously upon the shingle, it was a truly gloomy, out-of-the-world spot, far removed from the bustle of war's alarm. Lewin Rodwell, on gaining the beach at the end of a long straight path, turned without hesitation to the right, and walked to the south of the little creek of Anderby for some distance, until he suddenly ascended a low mound close by the sea, half-way between Anderby Creek and Chapel Point, and there before him stood a low-built fisherman's cottage, partly constructed of wood, which by day was seen to be well-tarred and water-tight. Within a few yards of the beach it stood, with two boats drawn up near and a number of nets spread out to dry; the home of honest Tom Small and his son, typical Lincolnshire fishermen, who, father and son, had fished the North Sea for generations.
