Tiled A Wolf Among the Sheep, the book has been written by journalist Graeme Webber, who started examining the case of the man known as The Little Pebble when covering the first trial at which Kamm was convicted of sexually abusing a teenaged follower.

Mr Webber also covered a later trial at which Kamm was again found guilty of sexually abusing another teenaged follower, and attended other legal action involving Kamm.

The early legal proceedings sparked a three-year investigation into Kamm and the religious group he founded - the Order of St Charbel based at a property in West Cambewarra.

And Mr Webber said what he uncovered was a history of devious behaviour and dubious financial dealings.

Kamm’s sexual exploits are detailed using letters he sent to the girls, who he named as two of the 12 queens and 72 princesses who were to help him repopulate the world in the new era after the apocalypse.

But it was Kamm’s financial dealings that most intrigued Mr Webber, and led to him calling for a Parliamentary inquiry into the regulations that allowed Kamm to set up a charity and accept many thousands of dollars in donations, before converting the charitable trust into a private company.

The charitable trust, the Marion Work of Atonement, received a donation of more than $300,000 from wealthy Japanese supporters in 1987, the book claims, with the money used to buy the Cambewarra property on which the order was established.

But when all the trust’s directors resigned in 1999, acting on Kamm’s prediction the world was about to end, Kamm was left as the sole director and the trust became a private company under Kamm’s control and ownership.

“Starting out as a self-declared bankrupt, Kamm assembled an extensive property portfolio and several shops under a complex structure of private companies and trust funds - all under his complete control,” Mr Webber said.
