Alton

In the novel Lord Edgware Dies, Alton is Lord Edgware's butler, who disappears after the police begin looking for another suspect.

He is a handsome young man, and is described by Hastings as a "Greek god of a butler". Poirot also remarks that he bears a resemblance to the actor Bryan Martin.

Poirot theorized that Alton had discovered his master dead on the night of the murder, and had taken an envelope of money that was on the table beside him. Alton had then slipped out of the house, passed the money to an accomplice, and let himself back into the house using Lord Edgware's latchkey.
