Mysterious Mr. Sabin by E. Phillips Oppenheim

Wolfenden lost his match upon the last hole; nevertheless it was a finely contested game, and when Mr. Sabin proposed a round on the following day, he accepted without hesitation. He did not like Mr. Sabin any the better -- in fact he was beginning to acquire a deliberate distrust of him. Something of that fear with which other people regarded him had already communicated itself to Wolfenden. Without having the shadow of a definite suspicion with regard to the man or his character, he was inclined to resent that interest in the state of affairs at Deringham Hall which Mr. Sabin had undoubtedly manifested. At the same time he was Helene's guardian, and so long as he occupied that position Wolfenden was not inclined to give up his acquaintance.

They parted in the pavilion, Wolfenden lingering for a few minutes, half hoping that he might receive some sort of invitation to call at Mr. Sabin's temporary abode. Perhaps, under the circumstances, it was scarcely possible that any such invitation could be given, although had it been Wolfenden would certainly have accepted it. For he had no idea of at once relinquishing all hope as regards Helene. He was naturally sanguine, and he was very much in love. There was something mysterious about that other engagement of which he had been told. He had an idea that, but for Mr. Sabin's unexpected appearance, Helene would have offered him a larger share of her confidence. He was content to wait for it.
