## Key lines

> The cause of death was aconitine poisoning.

The official medical examiner determined that Julius D'Arblay died from aconitine poisoning.

_This revelation at the inquest changes the nature of the case from accidental drowning to murder._

> It could not have been injected by deceased himself... The needle-puncture was in the back, just below the left shoulder-blade.

The poison was injected into a spot on the back that D'Arblay could not have reached himself, proving it was administered by someone else.

_This evidence rules out suicide and confirms homicide._
