The Silver Display Table A casual examination Dr. James Sheppard examines curios in the silver display table and notices its lid closing. Miss Russell also claims to have shut it as she left the drawing room. A weapon’s opportunity The murder dagger belongs among the objects in the table. Its access and disappearance make the seemingly decorative furniture part of the crime’s mechanics.

The Dagger Removed A missing weapon Flora insists the dagger was absent when she examined the silver display table. Her observation contradicts assumptions that it remained available to anyone later that evening. A clue with restricted access Poirot recognizes that the person who used the weapon could have taken it earlier. The dagger’s placement narrows the opportunity without immediately identifying the murderer.

The Study Armchair An odd position Parker recalls that a large chair stood away from the wall when the body was discovered. It was later returned to its proper place.

The Prints and the Boots A convincing trace Studded prints at the study window appear to prove Ralph entered and left. Inspector Raglan matches their pattern to shoes like Ralph’s.

The Letter and the Machine Two absences Mrs Ferrars’s blue envelope and letter disappear, while the Dictaphone that could explain Ackroyd’s later voice is also missing. Each absence changes the case’s shape. Evidence recovered in meaning The letter explains Sheppard’s fear, and the Dictaphone explains the false time of death. Their physical removal forms part of the same effort to control what investigators can know.
