Charlie Bezzina, a former high-profile Victorian homicide detective, has given a scathing account of the management process that ended his career and the careers of other senior officers.

The ABC has obtained the manuscript of Mr Bezzina's autobiography, which will be released next month.

In it the retired detective claims Chief Commissioner Simon Overland feared the elite homicide squad was too powerful.

He blames Mr Overland for orchestrating his professional demise.

With hundreds of investigations under his belt, Mr Bezzina was one of the country's elite detectives. But his career came to an acrimonious end.

In his autobiography, Mr Bezzina claims Mr Overland felt threatened by the experienced members of the homicide squad.

"I think they saw us as a threat, a bit of a power base growing within the department," he said.

"It would be us five, [the five senior sergeants from homicide], who would question things, because we basically said, 'well, we've got a right to, and what are they gonna do to us?'.

"Well, we found out what they could do to us."

Mr Bezzina fell victim to the rotation policy that moved experienced detectives out of their areas of expertise.

"We had high arrest rate, high conviction rate, high morale, no complaints and served the community well, I thought," he said.

"We had a high solvability rate within the homicide squad and I think it was a smokescreen to say, well, we need your skills elsewhere."

His comments are backed by Greg Davies, the head of the Police Association.

"More than 50 years of homicide investigating experience has been lost to the police force," he said.

"That is a gap that will take a very long time to replace, and worse still, it's a self-inflicted wound."

On a personal level, Mr Bezzina details the depths of his depression as he was forced out of the homicide role.

"I went through some really dark times when I came to the realisation of what the department had done to me and my colleagues," he said.

Now a self-employed handyman, Mr Bezzina says his reputation as an honest and clean cop was tarnished when he was not selected for a taskforce set up to review the murder of police informant Terrence Hodson.

It was an investigation he led.

Mr Bezzina questioned Mr Overland about the decision.

"Overland saved his greatest insult for last," he said.

"As I was about to leave, he made a final comment about the Hodson case that I will never forget, nor forgive: 'I knew you wouldn't solve it'."

Mr Overland did not wish to comment about the book.

Victoria Police was unaware the book had been written until it was contacted by the ABC.

Mr Bezzina has since been warned by police management that as a former officer he can still be charged with bringing the force into disrepute.
