He was now down by the back gate with his camera , where I found him turning it end-down and photographing the road . Together we made a thorough search of the woods and the road about the gate , but could discover absolutely nothing . After breakfast I improvised a dark room and developed the films , while Craig went down the back lane along the shore `` looking for clues , '' as he said briefly . Toward noon he returned , and I could see that he was in a brown study . So I said nothing , but handed him the photographs of the road . He took them and laid them down in a long line on the library floor . They seemed to consist of little ridges of dirt on either side of a series of regular round spots , some of the spots very clear and distinct on the sides , others quite obscure in the centre .
