He swept this possible cover with his lamp.
Was his imagination playing him a trick, or had he caught the briefest glimpse of a white face peering round the corner?
He put on his light again.

There was nothing visible.

He walked to the building and round it.
There was nobody in sight.

He thought he saw a dark form under the shadow of the building moving towards the belt of pines which surrounded the house on the three sides.

He put on his lamp again, but the light was not powerful enough to carry the distance required, and he went forward at a jog trot in the direction he had seen the figure disappear.
