APOLOGIA
Five a.m. I am very tired—but I have finished my task. My arm aches from writing.
A strange end to my manuscript. I meant it to be published some day as the history of one of Poirot's failures! Odd, how things pan out.
All along I've had a premonition of disaster, from the moment I saw Ralph Paton and Mrs. Ferrars with their heads together. I thought then that she was confiding in him; as it happened I was quite wrong there, but the the idea persisted even after I went into the study with Ackroyd that night, until he told me the truth.
Poor old Ackroyd. I'm always glad that I gave him a chance. I urged him to read that letter before it was too late. Or let me be honest—didn't I subconsciously realize that with a pig-headed chap like him, it was my best chance of getting him not to read it? His nervousness that night was interesting psychologically. He knew danger was close at hand. And yet he never suspected me.
The dagger was an afterthought. I'd brought up a very handy little weapon of my own, but when I saw the dagger lying in the silver table, it occurred to me at once how much better it would be to use a weapon that couldn't be traced to me.
