Gaslight by Patrick Hamilton is a Victorian thriller.  It is one of my favorite plays and the mystery and tension that grows throughout keeps the audience holding their breath and sitting on the edge of their seats. 

"While Jack Manningham is out on the town each evening, his wife, Bella, stays at home alone, believing she's losing her mind: she can't explain the disappearance of familiar objects, the mysterious footsteps overhead or the ghostly flickering of living room gaslights. However, questions about Jack's behaviour and true identity are aroused following the unexpected arrival of Detective Rough."

This website has the dialogue transcript for the film.  However, it doesn't list which character is saying what.  So if you've read the script before, it could be a helpful refresher.  If not, it'd be awfully confusing to try and figure out who is who.

In class Sam and Jey read the scene I chose, it was between Mrs. Manningham and Rough.  After the class discussion I absolutely agreed that I direct a different scene from the play.  I've chosen a part from the beginning between Mr. and Mrs. Manningham.

Matt and Jenna will be acting for my final.   

Bella Manningham is graceful.  She maintains poise while having the deer-in-the-headlights look when Jack criticizes her.

Mrs. Manningham: (after a pause, dropping her voice to almost a whisper) What is it?  What's the matter?  What is it now?

Mr. Manningham: (walking over to the fireplace, and speaking with his back to her) I have no desire to upset you, Bella, but I have just observed something very much amiss.  Will you please rectify it at once, while I am not looking, and we will assume that it has not hapened.

Mrs. M:  Amiss?  What's amiss?  For God's sake don't turn your back on me.  What has happened?

Mr. M: You know perfectly well what has happened, Bella, and if you will rectify it at once I will say no more about it.

Mrs. M: I don't know.  I don't know.  You have left your tea.  Tell me what it is.  Tell me. 

Mr. M: Are you trying to make a fool out of me, Bella?  What I refer to is on the wall behind you.  If you will put it back, I will forget the matter.

Mrs. M:  The wall behind me?  What?  (She turns)  Oh...Yes...The picture has been taken down.  Yes...The pictures...Who has taken it down?  Why has it been taken down...?

Mr. M: Yes.  Why has it been taken down?  Why, indeed?  You alone can answer that, Bella.  Why was it taken down before?  Will you please take it from wherever you have hidden it, and put it back on the wall again.  

Mrs. M:  But I haven't hidden it, Jack.  I didn't do it.  Oh, for God's sake lok at me.  I didn't do it.  I don't know where it is.  Someone else must have done it.

Mr. M:  Someone else?  Are you suggesting that I should play such a fantastic and wicked trick?

Mrs. M:  No, dear, no!  But someone else.  (She moves to him)  Before God, I didn't do it!  Someone else, dear, someone else.  (She reaches out to him)

Mr. M:  Someone else, eh?  Someone else. (Shaking her off)  Will you leave go of me.  You repel me--you half-witted thing.  (He walks over to the bell cord) We will see about "someone else".

Mrs. M:  Oh, Jack--don't ring the bell.  Don't ring it.  Don't call the servants to witness my shame.  It's not my shame for I haven't done it--but don't call the servants!  Tell them not to come.  (Moving to him and touching him again)  Let's talk of this between ourselves!  Don't call that girl in.  Please!

Mr. M:  (shaking her off violently)  Will you leave go of me and sit down there!  (He moves to the fireplace)  Someone else--eh?  Well--we shall see.

Mrs. M:  (rising)  Give me that Bible!  Give it to me!  Let me kiss it, too!  (She snatches it from him)  There!  (She kisses it)  There!  Do you see?  (She kisses it)  There!  Do you see that I kiss it?

Mr. M:  For God's sake be careful what you do.  Do you desire to commit sacrilege above all else?

Mrs. M:  It is no sacrilege, Jack.  Someone else has committed sacrilege.  Now see--I swear before God Almighty that I never touched that picture. (She kisses the Bible)  There!

Mr. M:  Then by God, you are mad, and you don't know what you do.  You unhappy wretch--you're stark gibbering mad--like your wretched mother before you.

Mrs. M:  Jack--you promised you would never say that again.  

Mr. M:  (after a pause)  he time has come to face facs, Bella.  If this progresses you will not be much longer under my protection.

Mrs. M:  Jack--I'm going to make a last appeal to you.  I'm going to make a last appeal.  I'm desperate, Jack.  Can't you see that I'm desperate?  If you can't, you must have a heart of stone.

Mr. M:  Go on.  What do you wish to say?

Mrs. M:  Jack, I may be going mad, like my poor mother--but if I am mad you have to treat me gently.  Jack--before God--I never lie to you knowingly.  If I have taken down that picture I have not known it.  I have not known it.  If I took it down on those other occasions I did not know it, either...Jack, if I steal your things--your rings, your keys--your pencils and your handkerchiefs, and you find them later at the bottom of my box, as indeed you do, then I do not know that I have done it...Jack--if I commit these fantastic, meaningless mischiefs--so meaningless--why should I take a picture down from its place?  If I do all these things, then I am certainly going off my head, and must be treated kindly and gently so that I may get well.  You must bear with me, Jack, bear with me--not storm and rage.  God knows I'm trying, Jack, I'm trying!  Oh, for God's sake believe that I'm trying, and be kind to me!

Mr. M:  Bella, my dear--have you any idea where that picture is now?

Mrs. M:  Why, yes.  I suppose it is behind the cupboard.

Mr. M:  Will you please go and see?

Mrs. M: (vaguely)  Yes...Yes...

        Mrs. Manningham moves to the UL cupboard and produces the picture from behind the cupboard

Yes, it's here.

Mr. M:  Then you did know where it was, Bella.  You did know where it was.

Mrs. M:  No!  No!  I only supposed it was!  I only supposed it was because it was found there before!  It was found there twice before.  Don't you see.  I didn't know--I didn't!  (She moves towards him with the picture in her hand)

Mr. M:  There is no sense in walking about the room with a picture in your hand, Bella.  Go and put it back in its proper place.

        Mrs. Manningham hangs the picture on the wall
