They will discuss how to create memorable characters, page-turning storylines, and bring the world of their mystery novels to vibrant life.
Local writer Helen Macfarlane, writing as Poppy Mann, says she does not consider herself to be a crime writer exclusively, though her novels all contain crime - be it murder or mayhem.
She has been writing stories since she was 10, but only seriously in the last 30 years.
Helen says she was pleasantly surprised to be selected for the Ngaio Marsh Awards 2018 with her novel The Night of the Moonflower.
"I encourage people to attend this event to interact with these authors, and discover their methods and ideas and research methods for writing their books.
"It may inspire other people to write a book themselves. It should be an informative and hopefully fun event."
Joanne started writing books later in life, though she has always had stories in her head, she says.
"It was like watching a movie in my head and writing it down. It was fun."
She says Murder in the Library is a great idea because it helps people get to know local authors.
She encourages people to come along to support local creative people and hopes it will encourage young writers to keep going.
Grant says he is looking forward to meeting local crime fiction fans and fellow writers.
Grant is also the co-founder for Rotorua Noir, which will be the first crime writing festival held in New Zealand.
It will be held on January 26 and 27 2019 at the Shambles Theatre, with a day of creative workshops on January 25.
Rotorua Noir will involve two days of panels, with five overseas writers attending from Australia, Iceland, Finland and the United Kingdom, along with New Zealand writers.
There will also be a short story competition, with the winner getting the chance to read their work on stage at the festival.
Founder and judging convenor of the Ngaio Marsh Awards Craig Sisterson says the Rotorua event was an expansion of their Murder in the Library series that has been running since 2015.
"Readers like to be thrilled, to feel excitement and a sense of vicarious danger, and also to be intrigued or puzzled.
"Crime fiction offers all of that, and allows authors to dig deep into many social issues and other important real-life topics, through the prism of an exciting, page-turning story that holds readers attention and can buffer against preachiness or soap-boxing."
No booking is required for Murder in the Library. For more information on Rotorua Noir go to www.rotoruanoir.com.
