Do you remember one evening when a whistle from the shadows on the road and a yokel's shout drove you out of Walter Hine's room, sent you creeping out of it as stealthily as you entered--nay, did more than that, for that whistle and that shout drove you out of Dorsetshire.

Ah! I see you remember." Garratt Skinner indeed had often enough been troubled by the recollection of that night.

The shout, the whistle ringing out so suddenly and abruptly from the darkness and the silence had struck upon his imagination and alarmed him by their mystery.

Who was the man who had seen?
And what had he seen?
Garratt Skinner had never felt quite safe since that evening.
