If this was really Cameron he did not wish that he should escape; but, at the same time, he saw no means of keeping him against his will, unless he went of his own accord to some place where other men could be called to help.

Quite apart, however, from the question whether the stranger was Cameron or not, Trenholme felt for him a sort of respect which character alone inspires, and which character written in a man's appearance has often power to inspire without a word or action to interpret it further.
