He wasn't a very good illusionist

Wadsworth:

Mrs. White, you've been paying our friend, the blackmailer, ever since your husband died under, shall we say, mysterious circumstances? Miss Scarlet:
Ah! [laughs] Mrs. White:
Why is that funny? Miss Scarlet:
I see! That's why he was lying on his back, in his coffin. Mrs. White:
I didn't kill him. Colonel Mustard:
Then why are you paying the blackmailer? Mrs. White:
I dont want a scandal, do I? We had had a very humiliating public confrontation. He was deranged. He was [points to head] Mrs. White:
a lunatic! He didn't actually seem to like me very much; he had threatened to kill me in public. Miss Scarlet:
Why would he wanna kill you in public? Wadsworth:
I think she meant he threatened, in public, to kill her. [rolls eyes] Miss Scarlet:
Oh. Was that his final word on the matter? Mrs. White:
Being killed is pretty final, wouldn't you say? Wadsworth:
And yet, he was the one who died, not you, Mrs. White, not you! Miss Scarlet:
What did he do for a living? Mrs. White:
He was a scientist, nuclear physics. Miss Scarlet:
What was he like? Mrs. White:
He was always a rather stupidly optimistic man. I mean, I'm afraid it came as a great shock to hime when he died, But, he was found dead at home. His head had been cut off, and so had his, uh... you *know*. [Colonel Mustard, Professor Plum, and Mr. Green cross legs] Mrs. White:
I had been out all evening at the movies. Miss Scarlet:
Do you miss him? Mrs. White:
Well, it's a matter of life after death. Now that he's dead, I have a life. Wadsworth:
But, he was your second husband. Your first husband also disappeared. Mrs. White:
But that was his job. He was an illusionist. Wadsworth:
But he never reappeared! Mrs. White:
[admittedly]
