"[to Poelzig] Do you know what I am going to do to you now? No? Did you ever see an animal skinned, Hjalmar? Ha, ha, ha. That's what I'm going to do to you now — fare the skin from your body...slowly...bit by bit!"

"[to Poelzig] How does it feel to hang on your own embalming rack, Hjalmar?"

"It's the red switch, isn't it Hjalmar? The red switch ignites the dynamite. (He activates one of the large switches.) Five minutes and Marmaros, you and I, and your rotten cult will be no more..."

"It has been a good game."

"Bus Driver: All of this country was one of the greatest battlefields of the war. Tens of thousands of men died here. The ravine down there was piled twelve deep with dead and wounded men. The little river below was swollen red, a raging torrent of blood. And that high hill yonder where Engineer Poelzig now lives, was the site of Fort Marmorus. He built his home on its very foundations. Marmorus, the greatest graveyard in the world."

"Peter Allison: [to Werdegast, about Poelzig] Well, I suppose we've got to have architects too. If I wanted to build a nice, cozy, unpretentious insane asylum, he'd be the man for it."

"Newspaper review: In Triple Murder, Mr. Alison's latest mystery thriller, he fulfills the promise shown...We feel, however, that Mr. Alison has, in a sense, overstepped the bounds of the matter of credibility. These things would never, but with a further stretch of the imagination, actually happen. We could wish that Mr. Alison would confine himself to the possible instead of letting his melodramatic imagination run away with him."

"Cum grano salis. Fortis cadere cedere non potest. Humanum est errare. Lupus pilum mutat, non mentem. Magna est veritas et praevalebit. Acta exteriora indicant interiora secreta. Aequam memento rebus in arduis servare mentem. Amissum quod nescitur non amittitur. Brutum fulmen. Cum grano salis. Fortis cadere cedere non potest. Fructu, non foliis arborem aestima. Insanus omnes furere credit ceteros. Quem paenitet peccasse paene est innocens."

"With a grain of salt. A brave man may fall but he cannot yield. To err is human. The wolf may change his skin but not his nature. Truth is mighty and will prevail. External actions show internal secrets. Remember when life's path is steep to keep your mind even. The loss that is not known is no loss at all. Heavy thunder. With a grain of salt. A brave man may fall but he cannot yield. By fruit, not by leaves, judge a tree. A madman believes all others mad. Who repents from sinning is almost innocent."

"Electric tension!"

"Deep their love! Great the risk!"

"Notorious woman of many desires! Fateful fascination! Bold intrigue!"

"Notorious woman of affairs... Adventurous man of the world!"

"Alexander Sebastian: [to Alicia] Many things have died for all of us. We mustn't let our spirit die with them. Perhaps I can help you to forget. I'd like to."

"John Huberman: You can put me away, but you can't put away what's going to happen to you and to this whole country. Next time, next time we are going to..."

"Mr. Devlin's been transferred to Spain...Well I guess he thought he was going stale here...I guess he thought he'd find Spain more interesting...Well, of course, it is more or less routine now."

"That sand that Devlin brought in shows uranium ore so now we know what we're driving at. And your job from now on will be to try to help us find out where that sand comes from."

"Now try to memorize the names of all the people you see there tonight. The men I mean. And get their nationalities. That's very important...And I suggest that you, uh, don't ask any questions. Just use your eyes and ears. They're a pretty keen and desperate bunch. Don't underestimate them."

"Gentlemen, I assure you, she's the perfect type for the job."

"[to Alex, while carrying Alicia] I'm taking her to the hospital to get the poison out of her...How'd you like your friends downstairs to know? They've yet to be told...You haven't forgotten what they did to Emil, have you Sebastian?...You've got your chance here and now. Tell them who she is."

"She wasn't drunk, she was sick. Maybe that's why she hasn't shown up. She looked like the ragged end of nowhere."

"I don't know if she'll do it...Well, I don't think she's that type of woman."

"[to Sebastian] Mr. Devlin has pestered me with his attentiveness ever since I arrived."

"I'm allergic to American agents. Their fine points don't particularly appeal to me."

"I don't know why I should feel so bad. When he told me a few years ago what he was, everything went to pot. I didn't care what happened to me. Now I remember how nice he once was. How nice we both were, very nice. It's a very curious feeling as if something had happened to me and not to him. You see, I don't have to hate him anymore or myself."

"[to Devlin] Go away and leave me alone. I have my own life to lead. Good times. That's what I want, and laughs with people I like. And no underhanded cops who want to put me up in a shooting gallery, but people of my own kind, who treat me right and like me and understand me."

"[to Devlin] Get out of my car, federal cop! Crashing my party, just like that buzzard with the glasses!"
