twenty minutes or so, fearing lest some labourers early astir might come to the spot before going to work, I was about to leave when, of a sudden, in a place where no grass grew upon the clay, I saw something that held me rigid. In the soft earth was the plain imprint of the small sole of a woman’s shoe, with a Louis XV heel! Lolita wore high heels of exactly that character, and took three’s in shoes. Was it possible that the footprint was hers? As I looked I saw others, both of a person advancing and receding. One was ill-defined, where she had apparently slipped upon the clay. But all of them I stamped out—all, indeed, that I could find. Yet was it possible, I wondered, to efface every one? If one single one remained, it might be sufficient to throw suspicion upon her. While engaged in this, something white caught my eye lying upon the grass about ten yards distant. I picked it up and found it to be a piece of white fur about an inch square that had evidently been torn bodily out of a boa or cape—the same fur that had been found between the dead man’s fingers. This I placed carefully in my cigarette-case and continued my work of effacing the damning footprints. There were other marks, of men’s boots, but whether those of the dead man or of our own I could not decide, so I left them as evidence for the police to investigate. My eyes were everywhere to try and discover the weapon with which the foul deed had been committed, for the assassin, I thought, might have cast it away, but my search was in vain. It had disappeared. Fully twenty distinct marks of those small well-shod feet I effaced by stamping upon them or scraping the surface with the trowel, and was preparing to return and keep the appointment with the doctor when of a sudden I saw, lying close behind the trunk of the giant oak, a half-smoked cigarette, which on taking up I found to be of the same brand as those found in the dead man’s pocket. He had therefore kept a tryst at that spot, and had smoked calmly and unsuspiciously in order to while away the time. Of men’s footprints in the soft ground there were a quantity, but then I remembered how all four of us had tramped about there, in addition to the victim himself, and I was not sufficiently expert in tracking to be able to distinguish one man’s tread from another’s.
