Imagine Forest

From whodunits to unsolved crimes, here are over 70 mystery writing prompts that will keep your readers hooked from beginning to end.

The mystery genre is all about gathering clues and evidence to solve a crime or mystery of some sort. Common mysteries to solve may include murder, kidnappings, theft and any other unsolved crimes. The thing that makes a mystery story so appealing is that no one knows who the true culprit is until the very end of the story. And the big reveal at the end is always shocking to the reader. The secret to a good mystery lies in theplot twist. You have to be two steps ahead of your readers Get inside the head of your readers and think, Who would your readers think the main culprit is? Then switch it around, and pick someone who is highly unlikely to be the real baddie.

You can pick a random prompt from our mystery writing prompts generator below to practice your plot twist skills on:

In a mystery novel, characters are a huge part of the mystery. Common characters may include:

Street smart detective They ask all the right questions, but are the answers to be trusted?

Bent cop Known for planting fake evidence at crime scenes.

Mysterious guy No one knows anything about them, and therefore they could be an easy suspect in the case.

The scapegoat The one everyone is blaming.

The obvious suspect All clues point to this person.

The unobvious suspect No real evidence against this person, but somehow they link to the crime in question.

When writing your mystery story think about the characters you would include carefully before diving in. We even recommend creating character profiles for each character, and maybe even a mind-map to show their connection to the crime in question.
