Questions regarding the Ending and the plot. Please help. (spoilers)

...exposing himself.

1) in the the third ending Tim Curry was actually Mr Boddy he invited them and the master manipulated the whole thing so that all of them were put in a position were they would basically kill off his informants ( Yvette, the Cook, the traveller, the cop ) people he knew they knew before hand such as Yvette being the woman who stole Ms White's husband. He had hired his butler to pretend to be him however the butler turned the tables on him and tried to get them to kill him instead which instead of derailing his plans actually enhanced them as now he had another person's death which he could blackmail them with and they all had weapons the butler had given them making it easier to frame them. The rest of the movie was the plan going exactly as it should have done them killing off all the informants which would give him the means to keep blackmailing them for more money he was basically tightening his grip on them. He'd been blackmailing them for a while he knew all about them and what they were capable of he basically just created a scenario where the end result is he would get more power.

2) In the third one he's an FBI agent undercover that's why he got that phone call from J Edgar Hoover the FBI had obviously found out about Mr Boddy's blackmail schemes and had sent him in there undercover. The whole persona of Mr Green was a facade to lure Mr Boddy out to expose him. He wasn't actually gay. It was the character he was playing. That's the joke his personality was the complete opposite of the one he'd been pretending to be all night. He seemed the most stupid and timid out if all of them but he was actually the smartest, bravest one.

3) It wouldn't have mattered he still would have had the means to blackmail them they were all accomplices in 6 murders since they all knew about it and didn't inform the police that's why he says the line about the police not being called and Professor Plum had already killed someone, the butler (the person pretending to be Mr Boddy) by that point the real Mr Boddy just needed the rest of the accomplices out of the way before they could have blabbed to police and also to give him more leverage over the rest of them cause he could easily just frame one of them and say that one of them did it with the information he knew about them the police would believe it.

4) It's such a low whisper it could have been man or a woman's voice when you whisper that low the sound of your voice makes it undistinugshable as to what gender you could be. Thereby it could easily have been a woman or a man. It's a device used in a lot of mystery films.

5) When Mr Boddy was pretending to be Wadsworth he said the reason he was being blackmailed was because his wife had friends who were communists that was a "red herring" a lie to throw them off track suspecting him. The film is set I think during the McCarthy era so there was a rampant fear in America about the dangers of of communism so the characters all had that fear which made it easy for them to believe Mr Boddy's story and not question it which allowed him to enact his plan to continue to blackmail them.
