Perry Mason – Genius detective, he always finds evidence that acquits his client, and his brilliant interrogative skills always cause the truly guilty party to break down and confess in the courtroom.
Lieutenant Tragg – Stereotypical "bumbling cop", he doesn’t get in Mason’s way, but doesn’t really work with him or make his job any easier. Tragg usually suspects Perry’s client, and doesn’t look much beyond the clear evidence in opposition to the obvious suspect.
Hamilton Burger – Perry’s rival in the courtroom. He always loses the case to Mason, and his client is usually convicted as the guilty party. He’s tried to get Perry Mason in trouble, but Perry is always able to argue his way out of the situation. Also, if you slightly edit his name, you get “hamburger”
Female Characters:
On left: Della Street; Right: Gertie
Della Street - the main female protagonist of the television series. She is Perry Mason's main advisor, and most trusted confidant. She is usually able to offer some much-needed female insight and womanly intuition. Though she and Mason are very close, there is no overt romantic interest between them.
Gertrude "Gertie" Lade - Usually only mentioned in the show as "Gertie", she is rarely seen, but is mentioned in nearly every episode. She works in Perry Mason's outer office, and announces all of his visitors to Della Street, who then asks Mason if he would wish to see them. Her role in the show is minor, but important nonetheless.
