The girl kept on with the same resolute pace, until she reached a spot where the canal found its outlet to the sea. There she turned aside and skirted the breakwater wall for a little distance, as if searching for something. The next moment she was scaling the breakwater wall. Colwyn was too far away to intercept her, or reach her if she slipped. He stopped and watched her climb to the top of the wall, and stand there, like a creature of the sea, with the spray leaping hungrily at her slight figure. He saw her take something from the bosom of her dress and cast it into the wild waste of seething waters in front of her. Having done this she turned to descend the breakwater. Colwyn had barely time to leave the path, and take refuge in the shadow of the wall, before she reached the path again and set out to retrace her steps across the lonely marshes. CHAPTER XI Colwyn waited on the marshes until the coming of the dawn revealed the breakwater and the sea crashing against it. A brief scrutiny of the white waste of waters, raging endlessly against the barrier, convinced him of the futility of attempting to discover what the innkeeper's daughter had thrown from the breakwater wall an hour before. The sea would retain her secret. The sea mist hung heavily over the marshes as Colwyn cautiously picked his way back along the slippery canal path. Sooner than he expected, the inn appeared from the grey mist like a sheeted ghost. Colwyn stood for a few moments regarding the place attentively. There was something weird and sinister about this lonely inn on the edge of the marshes. Strange things must have happened there in the past, but the lawless secrets of a bygone generation of smugglers had been safely kept by the old inn. The cold morning light imparted the semblance of a leer to the circular windows high up in the white wall, as though they defied the world to discover the secret of the death of Roger Glenthorpe. There was no sign of life about the inn as Colwyn approached it. The back door yielded to his pull on the latch, and he gained his room unobserved; apparently all the inmates were still wrapped in slumber. Colwyn spent half an hour or so in making some sort of a toilet. He had brought a suit-case with him in the car, so he changed his wet clothes, shaved himself in cold water, washed, and brushed his hair. He looked at his watch, and found that it was after six o'clock. He wondered if the girl Peggy was sleeping after her night's adventure. A swishing noise, somewhere in the lower regions, broke the profound stillness of the house. Somebody was washing the floor, somewhere. Colwyn opened his door and went downstairs. Ann, the stout servant, was washing the passage. She was on her hands and knees, with her back towards the staircase, swabbing vigorously, and did not see the detective descending the stairs. "Good morning, Ann," said Colwyn, pleasantly.
