Suspects for the murder-granted I have a lot!

I've just read this murder mystery again to try to understand it a bit more and get my head around it. I've thought about this a lot and I'm still really undecided I don’t really know who the murderer is. But there are some that I think could be in the pipe line and have an alibi for the murder. Ok just before you start reading my suspects granted I have suspected a lot of the cast but you know you can never be to careful hopefully at least one of my suggestion is right!. So bare with me but i think the suspects for the murder is either

Maggie- Ok so just an observation but 1.she is wearing a scarf and Ivor was strangled!!....coincidence I think not!!!. I think she could have done it because she didn’t like Ivors music and the singer she likes (Rob Stuart) has gone out of work because of him and she loves and would do anything for the Rod Stuart (the singer act whatever his name is) as a fan girl would. I also think she could have done it because she seems to really like Gerry and seems to be really sympathetic toward him (obviously she would be but that’s not the point) because Ida is having an affair. I think she could have maybe taken it into her own hands to sort out the relationship for her best friends? to make Ida come to her senses. It feels a bit like Ida has dragged her into this party and Maggie is a bit fed up with her?.

Frank-Lee- 1. He wanted to play his own music and wanted to be in the spot light for once 2. He wanted some credit as he done all the work for Ivor and never got any recognition

Bet or Rob- These are both brother and sister and I think they could have been trying to help each other out for both Bet’s business and Rob’s career. So 1. Killing Ivor would help publicity for Bet’s pub as he’s a small star 2. Bet could want to get back at Ivor for giving Rob a breakdown as she had to put up with the consequences of Robs breakdown all because of Ivor kicking him out of the band.

Ida- The obvious reason is the affair BUT also she went to question ivor but apparently he was already dead. I don’t know if I believe this. She could have wanted her old life back and didn’t want to go to America with Ivor (like she says) and could have killed him because she saw no other way out. She even says that she was stupid to have an affair in the script. Also she’s very worried about the flower bed (the chrysanthemums) and if she loved Ivor you would have thought she would be very upset really I don’t know maybe it was a cover up? I don’t know

Trevor- I don’t know I just think he’s suspicious. He’s always like in mostly everything he says that he was working early but maybe he wasn’t?

Gerry- also for the obvious reason of his wife’s affair and he had a bit of a fight (not really a fight) with Ivor the night before about a suspicious circumstance.

Also just throwing it out there Melody is very quiet so I don't know weather this is enough to be a suspect she could be fed up with Ivor? but yes I don't know I'll leave it there anyway again I hope at least one of these is right!.
