What happens

Dr. Sheppard writes his confession at five in the morning, revealing that he murdered Roger Ackroyd. He describes his meticulous planning, including the use of a dictaphone to create an alibi, and his manipulation of events to cast suspicion on others. He reflects on his motives, his fear of his sister Caroline discovering the truth, and his decision to take his own life with veronal, addressing the manuscript to Poirot.

Key passages

  • I meant it to be published some day as the history of one of Poirot’s failures!

    Sheppard originally intended his manuscript to show Poirot being outsmarted.

    Irony: the manuscript becomes a confession instead.

  • 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.

    Sheppard decided to use Ackroyd's own dagger instead of his own weapon to avoid suspicion.

    Reveals premeditation and cunning.

  • I did what little had to be done!

    Sheppard downplays his actions of removing the dictaphone and moving the chair.

    Example of his deceptive wording throughout the narrative.
