A Mansfield author is to promote his crime thriller books at two special days at the Tesco Extra store on Chesterfield Road South in the town.

Trevor Negus, who released his fourth book, Two Wrongs, in January, will be in the store on 23rd and 24th March.

Trevor, (above), who spent two years as a child in Australia before moving to Mansfield, joined Nottinghamshire Police in 1975.

In a varied 30-year career he spent six years as a firearms officer and police sniper, and 12 years with the CID, including time spent as a tier five interviewer dealing with the interviews of murder suspects.

Trevor retired from the police in 2007 and now concentrates on his writing, which he had done throughout his adult life, contributing short stories for magazines.

His first novel, The Coal Killer, is a dark crime thriller set in Nottinghamshire in 1984 at the heart of the year-long bitter miners’ strike.

The Exodus Murders and A Different Kind Of Evil completed the Chief Inspector Flint trilogy.

His latest book, Two Wrongs, is set in 1987. It follows the story of what happened when drug-related crime rose in Nottinghamshire after Barry Tate, who had controlled the distribution of illegal drugs across the county, was jailed.

Standing in the way of the downward spiral into lawlessness are the Special Operations Unit (SOU), the armed response teams of Nottinghamshire Police.

But the war on crime takes an unexpected and personal turn when the wife of a serving SOU officer — and the barrister responsible for the successful prosecution of Barry Tate — is abducted.

Two Wrongs is the first of a new trilogy focusing on the police firearms response teams.

Trevor is currently working on the second book in the series, The Root Of All Evil.

He will be in Tesco signing copies of his books from 9am to 6pm on Saturday, 23rd March, and from 10am to 4pm the following day, Sunday 24th.

He said: “Thank you to Tesco for supporting a local author — it is unusual for a big store will do that.

“It is very much appreciated and I hope people will support the two days.”

Anyone who can’t get to Tesco over the weekend and wants to buy copies of Trevor’s book can find them for sale on Amazon.
