Can you recommend some halloween mystery novels?

One great halloween themed murder mystery novel is 'The Halloween Tree' by Ray Bradbury. It weaves a spooky tale around the holiday. Another is 'Murder on Halloween' by various authors which is filled with twists and turns. Also, 'The Hollow' by Agatha Christie has a certain eerie atmosphere that can be associated with halloween.

Often, they have a spooky setting like old mansions, graveyards or dark forests which are typical halloween settings. This creates an atmosphere of mystery and fear.

Sure. There's a great one about a magic Halloween costume. A kid finds an old costume in the attic and when he puts it on for Halloween, he starts having strange adventures. He can fly and visit different spooky lands. But he has to solve the mystery of why the costume has this magic before midnight or he'll be stuck in the spooky world forever.

One great 'adult halloween novel' could be 'The Halloween Tree' by Ray Bradbury. It's a classic that weaves together elements of Halloween traditions, mystery, and a touch of the supernatural. It's suitable for adult readers who enjoy stories with deeper themes and a spooky atmosphere.

There is also 'Haunted Hearts on Halloween'. This novel is set in a haunted town during Halloween. The main characters are drawn to each other while exploring the spooky happenings in the town. The author does a great job of creating an atmosphere that is both scary and romantic at the same time.

One great Halloween novel is 'The Legend of Sleepy Hollow' by Washington Irving. It's a classic that features the iconic Headless Horseman. Another is 'Dracula' by Bram Stoker. The story of the vampire Dracula is full of mystery and horror, perfect for Halloween. And 'Frankenstein' by Mary Shelley also fits well. It explores themes of creation and monstrosity which are very Halloween - esque.

I highly recommend 'The Haunting of Hill House' by Shirley Jackson. It's a spooky mystery about a group of people staying in a haunted house. The atmosphere is really creepy. Another good one is 'The Turn of the Screw' by Henry James. The mystery of the ghosts and what they want from the governess is really interesting. And 'Midnight Dreary' by Douglas Preston and Lincoln Child is also great for Halloween, with its mystery and horror elements.

One popular 'halloween series novel' is 'The Halloween Tree' by Ray Bradbury. It's a great read with a spooky and mysterious atmosphere that really captures the essence of Halloween.

One modern adult Halloween novel is 'The Halloween Tree' by Ray Bradbury. It weaves a spooky and magical tale around the traditions of Halloween.

'Goosebumps' series by R.L. Stine is also very popular. There are many books in this series, each with its own spooky tale. They often involve kids facing supernatural or creepy situations, which is exciting for kids during halloween time.
