They represent the heels of the boots worn by the assassin, of which I found a most perfect impression near the ditch, where the key was picked up.

On these sheets of paper, I have marked in outline the imprint of the foot which I cannot take up, because it is on some sand.

Look! heel high, instep pronounced, sole small and narrow,--an elegant boot, belonging to a foot well cared for evidently.

Look for this impression all along the path; and you will find it again twice.

Then you will find it five times repeated in the garden where no one else had been; and these footprints prove, by the way, that the stranger knocked not at the door, but at the window-shutter, beneath which shone a gleam of light.
