Leonard came towards Normanstand next forenoon in considerable mental disturbance.

In the first place he was seriously in love with Stephen, and love is in itself a disturbing influence.
Leonard's love was all of the flesh; and as such had power at present to disturb him, as it would later have power to torture him.

Again, he was disturbed by the fear of losing Stephen, or rather of not being able to gain her.

At first, ever since she had left him on the path from the hilltop till his interview the next day, he had looked on her possession as an 'option,' to the acceptance of which circumstances seemed to be compelling him.

But ever since, that asset seemed to have been dwindling; and now he was almost beginning to despair.
