Laurieton resident Ally Chumley says the case of missing boy William Tyrrell is one which many feel a deep personal connection to.
Her book Searching for Spiderman is due to be released on July 22 and it includes Ally's own extensive research and interviews after following the case for the past five years, since William's disappearance from Kendall in 2014.
Ally said when she heard a three-year-old boy had gone missing from a property in Kendall the incident grabbed her attention.
Ally decided to help and bring together members of the community to assist in the widespread search for William through the dense bushland at the back of Beneroon Drive.
Ally is a trained English teacher and has also written 45 educational text books.
She said she utilised her skills as a researcher to try and draw some conclusions about what might have happened to William.
As a local, Ally said she knew many of the people who came forward to give evidence at the inquest into William's disappearance at the NSW Coroner's Court in 2019 and 2020.
She meticulously took notes at the inquest to assist with her research for the book.
The inquest will resume in October, with the NSW Coroner's Court hearing potential witnesses are withholding information.
Ally said she had previously known Bill Spedding prior to him being named as a person of interest.
She decided she would be an advocate for him, given the media scrutiny he came under.
"It's easy to criticise people from a distance without really knowing the family and the situation," she said.
"It was suddenly personally involving."
Ally said it's difficult to maintain objectivity when writing about the case.
"There's no way any writer should do that," she said.
"As a reader you're looking through the lens of the writer's opinion and I was not trying to straight out investigate the case.
"I was trying to tell the story of essentially a local person's involvement in it, rather than just the police findings."
Ally does come to her own conclusions about what might have happened to William within the book.
"The police and the detectives obviously know far more than what we do," she said.
"What I tried to base my conclusions on were reactions I saw and witnessed in the court."
Ally believes there is hope William's family will receive closure about what has happened to their boy.
"I think we're a lot closer to a resolution than what has been spoken about in the media," she said.
Ally is friends with a lot of the locals in Kendall and the Camden Haven and was able to interview many of the people directly involved in the case.
Ally dedicated the book to the residents of Kendall.
Meanwhile, former NSW lead detective Gary Jubelin was convicted and fined $10,000 for making illegal recordings during his role at the head of Strike Force Rosann during the investigation.
In June Mr Jubelin appealed his conviction and will next face court in mid-August.
