I was a microbiologist for over 30 years at the Veterinary Laboratories Agency, Weybridge where I led a small team of scientists involved in the diagnosis of bovine tuberculosis in animals and was also Great Britain's designated international expert on bovine tuberculosis for the OIE (World Animal Health Organisation).  

I began writing fiction to amuse myself, friends and family in my early teens.  My first novel, Cogrill's Mill, was  released as an e-book in 2005 and as a paperback book in 2009.  I decided to use the  penname of Jack Lindsey for this novel to separate my fictional work from that I published as a microbiologist.  A second novel, Victim of Compromise was published on 15 February 2010.  The story is darker and more explicit than the first novel so it is published under a second penname of Luke Johnson.  

 Crime and Passion, a collection of twelve contrasting short stories by Luke Johnson and Jack Lindsey, was published in ebook format in August 2011.  A second Jack Lindsey novel, Gifford's Games, was launched in June 2012 in the month preceding the London Olympic games.  However, it is billed as having nothing to do with the Olympics but everything to do with games.

I now concentrate on my fiction writing and live in Woking, England with my wife and two children.
