The lumber room at the other end of the passage had not been locked, and the door stood ajar. Colwyn entered it, and by the glancing light of the torch looked over the heavy furniture, mouldering linen, and stiffly upended bedpoles and curtain rods which nearly filled the room. The clock of a bygone generation stood on the mantel-piece, and the black winding hole in its white face seemed to leer at him like an evil eye as the light of the torch fell on it. But nobody had been in the room. The dust which encrusted the furniture and the floor had not been disturbed for months.
Colwyn returned, puzzled, to his own room. Could he have been mistaken? Was it possible that the sound he had heard had been caused by the door of the lumber room swinging to? No! the sound had been too clear and distinct to admit the possibility of mistake, and it had been made by the grating of a key in a lock, not by a swinging door. He stood in the darkness by his open door, listening intently. Several minutes passed in profound silence, and then there came a scraping, spluttering sound. Somebody not far away had struck a match. Looking cautiously out into the passage, he saw, to his utter amazement, a gleam of light appear beneath the door in which the dead man lay. The next moment the gleam moved up the line of the door sideways, cutting into the darkness outside like a knife. The gleam became broader until the whole door was revealed. Somebody inside was opening it. Even as he looked a hand stole forth from the aperture through which the light streamed, and rested on the jamb outside.
Colwyn was a man of strong nerves, but that sudden manifestation of light and a human hand from a sealed death chamber momentarily unbalanced his common sense, and caused it to swing like a pendulum towards the supernatural. He would not have been surprised if the light and the hand had been followed by the apparition of the murdered man on the threshold, demanding vengeance on his murderer. The feeling passed immediately, and with the return of reason the detective stepped back into his room, closed his door quietly, and watched through a knife's edge slit for the visitor to the death chamber to appear.
The door of the dead man's room opened gently, and the face of the innkeeper's daughter peered forth into the darkness, her impassive face, behind which everything was hid, showing like a beautiful waxen mask against the light of the candle she held in her hand. Her clear gaze rested on Colwyn's door, and it seemed to him for a moment as though their glances met through the slit, then her eyes swept along the passage from one end to the other. As if satisfied by the scrutiny that she had nothing to fear, she stepped forth from the death chamber, closed and locked the door behind her, withdrew the key, walked swiftly along the passage to the head of the stairs, and descended them.
Colwyn opened his door and followed her. He paused outside to pick up the boots which he had placed there to be cleaned, and carrying them in his hand, ran quickly to the head of the stairs. Looking over the landing, he saw the girl reach the bottom of the stairs and turn down the passage towards the back door, still carrying the lighted candle in her hand.
When Colwyn reached the bottom, the girl and the light had disappeared. But a swift gust of wind in the passage revealed to him that she had gone out by the back door, and closed it after her. He followed along the passage till he felt the latch of the back door in his hand. The door yielded to the lifting of the latch, and he found himself in the open air.
It was a grey northern night, with a bitter wind driving the sea mist in billows over the marshes, and a waning half moon shining fitfully through the dingy clouds which scudded across a lead-coloured sky. By the light of the moon he saw the figure of the girl, already some distance from the house, swiftly making her way along the reedy canal path which threaded the oozing marshes.
Colwyn was not a stranger to marshlands. He had waded knee-deep from dawn to dusk through Irish bogs after wild geese; he had followed the migratory seafowl of Finland, Russia and Serbia into their Scottish breeding haunts, and he had once tried to keep pace with the sweep of the Bore over the Solway Marshes, but he had never undertaken a task so difficult as following this girl across a Norfolk marshland. The path she trod so unhesitatingly was narrow, and slippery, with the canal on one side and the marshes on the other. In keeping clear of the canal Colwyn frequently found himself slipping into the marshes. His feet and legs speedily became wet and caked with ooze, and once he nearly lost one of his boots, which he had pulled on hurriedly outside the inn, and left unlaced.
But the girl walked straight on with a swift and even gait, treading the narrow path across the morass as securely as though she had been on the high road. Colwyn soon realised that the path they were following was taking them straight across the marshes to the sea. The surging of the waves against the breakwater sounded increasingly loud on his ears, and after a while he saw the breakwater itself rise momentarily out of the darkness like a yellow wall, only to disappear again. But presently it was visible once more, looming out in increasing clearness, with a ghostly glimmering of the grey waters of the North Sea heaving turbulently outside.
As they neared the breakwater the path became drier and firmer, and the light of the moon, falling through a ragged rift in the scurrying clouds, showed a line of sand banks and strips of tussock-land emerging from the marshes as the marshes approached the sea.
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
