Murder by Natural Causes

Arthur Sinclair:
[to Allison] You ignored the first rule of infidelity, darling... never cheat on a man who employs a private detective.

Arthur Sinclair:
[about George] He must love you very much.

Allison Sinclair:
[defiantly] He does!

Arthur Sinclair:
Apparently. He even let you have an affair with another man, but that served another purpose, didn't it?

Garden Party Hostess:
[to Allison] You must have a lot of courage, my dear... married to a mind reader? How could one keep secrets?

Arthur Sinclair:
I'd give up those coffee comemrcials if I were you and concentrate on bigger things. Take it from me, those reviews of your play were unfair! Any time you need a testimonial...

Gil Weston:
Shut up!

Arthur Sinclair:
Watch your language, Mr. Weston. You're already in a great deal of trouble.

[last lines]

Allison Sinclair:
What are you going to do?

[Arthur, pointing a gun at her, smiles and says nothing]

Allison Sinclair:
Tell me, Arthur!

Arthur Sinclair:
[pause, then] I have a suggestion for you, darling... why don't you read my mind?

Allison Sinclair:
He [meaning George] killed you!

Arthur Sinclair:
Not quite... he *shot* me. There's a difference.

Arthur Sinclair:
Another lesson in infidelity, darling... if a private detective can find out about Lover A, he can almost certainly find out about Lover B.

Arthur Sinclair:
[to George] Allison tried to have me killed tonight. [George stares at Allison, but says nothing] Didn't you hear me? I said-...

Arthur Sinclair:
I heard you, Arthur. [to Allison] What went wrong?

Allison Sinclair:
He was expecting it.

George Brubaker:
[glances at Arthur, then] Impossible.

Allison Sinclair:
He found out about Gil months ago. Tonight was a set-up!

Arthur Sinclair:
[to telephone operator after his pacemaker test] Am I alive?

Gil Weston:
You are one cold-blooded lady.

Allison Sinclair:
[slowly slides a hand into the open front of Gil's bathrobe] Cold-blooded?
