What does the ghost reveal about manner of his death in hamlet?

The ghost of Hamlet's father reveals that he was murdered by his own brother, Claudius, who then married his wife, Gertrude. He does not reveal the specific method of murder, but does mention that Claudius poured poison into his ear while he slept, leaving him vulnerable.

Here's a breakdown:

* Murderer: Claudius, Hamlet's brother

* Method: Poison poured into the ear while sleeping (implied, not directly stated)

* Circumstance: The murder happened while Hamlet's father was sleeping in the garden, leaving him vulnerable to the attack.

The ghost's revelation is key to the play's plot. It fuels Hamlet's thirst for revenge, driving him to act (or rather, not act) in a way that ultimately leads to tragedy.
