In less than the stipulated half-hour she had reached the village—­that bleak, depressing-looking village, with its miscellany of dull little houses, through which one must pass, as through some dreary gateway, to reach the wild, sea-girt beauty of the coast itself.  Leaving her cycle in charge at a cottage, Nan set out briskly on foot down the steep hill that led to the shore.  She was conscious of an imperative need for movement.  She must either cycle, or walk, or climb, in order to keep at bay the nervous dread with which her visit to Trenby had inspired her.  It had given her a picture of Roger’s home and surroundings—­a brief, enlightening glimpse as to the kind of life she might look forward to when she had married him.

It was all very different from what she had anticipated.  Even Roger himself seemed different in the environment of his home—­less spontaneous, less the adoring lover.  Lady Gertrude’s influence appeared to dominate the whole house and everyone in it.  But, as Nan realised, she had given her promise to Roger, and too much hung on that promise for her to break it now—­Penelope’s happiness, and her own craving to shut herself away in safety, to bind herself so that she could never again break free.

Her unexpected meeting with Peter the previous evening had shown her once and for all the imperative need for this.  The clasp of his hand, the strong hold of his arms about her as he bore her across the stream, the touch of his lips against her hair—­the memory of these things had been with her all night.  She had tried to thrust them from her, but they refused to be dismissed.  More than once she had buried her hot face in the coolness of the pillows, conscious of a sudden tremulous thrill that ran like fire through all her veins.

And that Peter, too, knew they stood on dangerous quicksands when they were alone together, she was sure.  This morning, beyond a briefly-worded greeting at breakfast, he had hardly spoken to her, carefully avoiding her, though without seeming to do so, until her departure to Trenby Hall made it no longer necessary.  She hoped he would not stay long at Mallow.  It would be unbearable to meet him day after day—­to feel his eyes resting upon her with the same cool gravity to which he had compelled them this morning, to pretend that he and she meant no more to one another than any two other chance guests at a country house.

Nan’s thoughts drove her swiftly down the steep incline which descended towards the cove and, arriving at its foot, she stopped, as everyone must, to obtain the key of the castle from a near-by cottage.  The old dame who gave her the key—­accepting a shilling in exchange with voluble gratitude—­impressed upon her the urgent necessity for returning it on her way back.

“If you please, lady, I’ve lost more than one key with folks forgettin’ to return them,” she explained.

“I won’t forget,” Nan assured her, and forthwith started to make her way to the top of the great promontory on which stands all that still remains of King Arthur’s Castle—­the fallen stones of an ancient chapel, and a ruined wall enclosing a grassy space where sheep browse peacefully.
