I had just finished breakfast, and deeply perplexed had risen from the table in order to get a box of matches to light a cigarette, when my black cat got between my feet and tripped me up. I fell forwards, making a clutch at the table-cloth. My forehead struck the corner of the fender and the last thing I remembered was a crash of falling crockery. Then all became darkness. My parlour-maid found me lying face downwards on the hearth-rug ten minutes later. My cat was sitting near my head, blinking contentedly at the fire. A little blood was oozing from a wound above my left eye.
