She was so eager to be of use to him that she did not wait for his reply, but ran quickly and noiselessly along the passage, and down the stairs. In a very brief space she returned with the key, which she placed in his hand. "Is there anything else I can do?" she asked.
"Nothing, except to tell me where you got the key. I want to put it back again without anybody knowing it has been used."
"It hangs on the kitchen dresser—the second hook. You cannot mistake it, because there is a padlock key and one of my father's fishing lines hanging on the same hook."
"Then that is all you can do. I will let you know if I want to see you at any time."
"Thank you. Good night!" She was gone without another word.
Colwyn stood at his door watching her until she disappeared into the passage which led to her own room. Then he turned into his bedroom and shut the door behind him.
He walked to the window and threw it open. The sea mist, driving over the silent marshes like a cloud, touched his face coldly as he stood there, meditating on the strange turn of events which had brought him back to the inn to pursue his investigations into the murder at the point where he had left them more than a fortnight before. In that brief period how much had happened! Penreath had been tried and sentenced to death for a crime which Colwyn now believed he had not committed. Chance—no, Destiny—by placing in his hand a significant clue, had directed his footsteps thither, and left it for his intelligence to atone for his past blunder before it was too late.
It was with a feeling that the hand of Destiny was upon him that Colwyn turned from the window and regarded the little room with keen curiosity. Its drab interior held a secret which was a challenge to his intelligence to discover. What had happened in that room the night Ronald slept there? He noted the articles of furniture one by one. Nothing seemed changed since he had last been in the room, the day after the murder was committed. There was a washstand near the window, a chest of drawers, a dressing table and a large wardrobe at the side of the bed. Colwyn looked at this last piece of furniture with the same interest he had felt when he saw it the first time. It was far too big and cumbrous a wardrobe for so small a room, about eight feet high and five feet in width, and it was placed in the most inconvenient part of the room, by the side of the bed, not far from the wall which abutted on the passage. He opened its double doors and looked within. The wardrobe was empty.
Colwyn made a methodical search of the room in the hope of discovering something which would throw light on the events of the night of the murder. Doubtless the room had not been occupied since Penreath had slept there, and he might have left something behind him—perhaps some forgotten scrap of paper which might help to throw light on this strange and sinister mystery. In the detection of crime seeming trifles often lead to important discoveries, as nobody was better aware than Colwyn. But though he searched the room with painstaking care, he found nothing.
It was while he was thus engaged that a faint rustle aroused his attention, and looking towards the corner of the room whence it proceeded, he saw a large rat crouching by the skirting-board watching him with malevolent eyes. Colwyn looked round for a weapon with which to hit it. The creature seemed to divine his intentions, for it scuttled squeaking across the room, and disappeared behind the wardrobe.
