I was near the door of the morning room, and for a second slipped inside and switched on the electric light. Then I took from my vest pocket the tiny little object I had found and carefully examined it. My heart stood still. My eyes riveted themselves upon it. The mystery was solved. I alone knew the truth! CHAPTER VII. THE MAN SHORT AND HIS STORY. A light footstep sounded behind me, and scarcely had I time to thrust the little object hastily back into my pocket when my well-beloved entered in search of me. "What do the police think, Ralph?" she asked eagerly. "Have they any clue? Do tell me." "They have no clue," I answered, in a voice which I fear sounded hard and somewhat abrupt. Then I turned from her, as though fully occupied with the investigations at which I was assisting, and went past her, leaving her standing alone. The police were busy examining the doors and windows of the back premises, kitchens, scullery, and pantry, but could find no evidence of any lock or fastening having been tampered with. The house, I must explain, was a large detached red brick one, standing in a lawn that was quite spacious for a suburban house, and around it ran an asphalte path which diverged from the right hand corner of the building and ran in two parts to the road, one a semi-circular drive which came up to the portico from the road, and the other, a tradesmen's path, that ran to the opposite extremity of the property. From the back kitchen a door led out upon this asphalted tradesmen's path, and as I rejoined the searchers some discussion was in progress as to whether the door in question had been secured. The detective-sergeant had found it unbolted and unlocked, but the cook most positively asserted that she had both locked and bolted it at half-past ten, when the under housemaid had come in from her "evening out." None of the servants, however, recollected having undone the door either before the alarm or after. Perhaps Short had done so, but he was absent, in search of the dead man's widow. The police certainly spared no pains in their search. They turned the whole place upside down. One man on his hands and knees, and carrying a candle, carefully examined the blue stair-carpet to see if he could find the marks of unusual feet. It was wet outside, and if an intruder had been there, there would probably remain marks of muddy feet. He found many, but they were those of the constable and detectives. Hence the point was beyond solution. The drawing-room, the dining-room, the morning-room, and the big conservatory were all closely inspected, but without any satisfactory result. My love followed us everywhere, white-faced and nervous, with the cream chenille shawl still over her shoulders. She had hastily put up her wealth of dark hair, and now wore the shawl wrapped lightly about her.
