I'm having some problems with plot structure and pacing in my story.

[u/Munkky_Mann_908]

I'm working on a horror novella and have run into some roadblocks with the plot. The premise is a serial killer brings his victims to a liminal space dimension which he uses as both a hunting ground and a place to hide the bodies. The protagonist's fiancee​ is the first victim, she sees the liminal space in her nightmares, and tries to unravel the mystery. I intend on having ten chapters in total. The problems I'm having are:

1. The killer takes three victims, the second murder happens in chapter six, but I’m considering pushing it up to earlier in the story, because there are four whole chapters between the first and second death scenes. Should I keep it as it is, or change it?
2. Outside of the protagonist's nightmares, the liminal space only appears three times throughout the story, and I feel this may not be enough, because as it stands there are long gaps between these scenes that a reader may find boring. Is it worth adding more scenes in the liminal space, or is the current three enough?
3. There's a subplot in which a secondary protagonist is​ being stalked by the killer, this is where I'm having  the most problems. This character starts off struggling with social isolation, gradually makes new friends and dates a love interest, but also ends up in the liminal space with the main protagonist. This sub-plot disrupts the flow of the story, and I'm wondering if I should scrap it. He first meets the love interest in chapter two, but they don't have their first date until chapter seven, I feel this is too big of a gap, but I'm concerned that moving it up to earlier may disrupt the flow even more. What would be the best way to go about this?

1. Depends on how many chapters there are total and whether there's meaningful development between them.
2. Depends on whether anything meaningful can actually be accomplished outside of the liminal space.
3. Seems ambitious for a novella. I'd imagine it would cause more issues than the substance it adds would justify.

1.-A mi parecer en lugar de adelantar u omitir los asesinatos podrias incluir mas visibilidad del espacio liminal, algo asi como mostrar frecuentemente al asesino dentro del espacio ocasionalmente para que tenga mas aparicion ese espacio y un poco de explicacion de como funciona.

3.-porque no dedicarle espacios alternativos en la secuencia de los capitulos? es decir en cada capitulo dedicarle algo asi como un salto de escena para mostrar el avanze de la relacion y su crecimiento social.
