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.

Ally said it's difficult to maintain objectivity when writing about the case.

"There's no way any writer should do that," she said.
