What a horror plot needs
- Delay the reveal. What readers imagine is worse than what you show. Keep the threat partly off-page as long as you can.
- Escalate the rules. Horror works when the threat follows rules the reader can learn, then breaks one at the worst moment.
- Make escape cost something. The easy way out should require giving up someone or something the hero loves.
6 horror plot ideas
- A night-shift nurse in a ferry that crosses the same stretch of water every night: the baby monitor picks up a voice answering the hero's questions. Then they learn the last family left the house in the exact same way.
- A teenage babysitter in an empty ski resort out of season: a photograph of the family appears with one extra person in it. Then the hero is the one the town has been waiting for.
- A grieving father who moves his family to the country in a hospital wing closed since the 1970s: the neighbours start leaving their doors open at night. Then the haunting is a warning, not a threat.
- A sound engineer restoring old tapes in a ferry that crosses the same stretch of water every night: a tape arrives with a recording of the hero sleeping. Then escaping is possible, but only for one of them.
- A hospice volunteer in an empty ski resort out of season: the house has one more room than the floor plan. Then the hero realises the thing has been inside since before they arrived.
- An estate agent selling a house nobody will buy in a hospital wing closed since the 1970s: a child says the woman in the garden is their real mother. Then the person they trusted most has been helping it.

Questions writers ask
What makes a good horror plot?
A sympathetic character, a threat that is personal, and a slow loss of safety. The best horror plots take away the hero's options one by one.
How do I build suspense in a horror story?
Let the reader know more than the character, slow down at moments of dread, and end scenes just before the payoff.
Should horror stories have happy endings?
Not necessarily. Many end with survival at a cost or with an ambiguous final image. What matters is that the ending answers the question the story raised.
