The second, the impression of the left foot, was not quite so far from the first as the first was from the window, and here again the heel was the more lightly defined.

But there was this difference--the mark of the toe, which was pointed in the first instance, was, in this, broader and a trifle blurred.

Close beside it the right foot was again visible; only now the narrow heel was more clearly defined than the ball of the foot.

It had, indeed, sunk half an inch into the soft ground.

There were no further imprints.
