I need ideas to write a harboild or thriller mystery?

Question

Thank you. Something interesting. or a cool movie you saw before

Answer 1

Somebody coming out from the cupboard  at midnight would thrill the children especially the cat-man!

Answer 2

How about a story where a girl finds out that dolls in her old dollhouse comes to life at night and the doll act out a play that shows the death of her parents when she was very young. The mystery is to find out who killed her parents and why.

Answer 3

i dont know what a harboild is, or if ur talking about a movie or a book but

a murderer who kills people with a slash in the throat and heart; an ex murderer is framed but its rlly not him

a cat/dog myseriously appears out of no where (make it black or white) right before someone dies (can be a day, an hour, a minute, or a secondd)

Answer 4

well, if you want to write one,see something that can inspire you, jot it down and think of things youve seen and keep going from there.
