Former Greenock GP and Second World War hero is the inspiration for a new adventure novel

Glasgow University graduate Dr Peter Barron was one of the town's first NHS family doctors after serving as a British Army medical officer in operations in North Africa and Europe.

After the war he spent 30 years in practices in Port Glasgow and then Greenock, after meeting his wife Dr Agnes Barron, a consultant at the Eye Infirmary.

In a real family affair his son Dr Colin Barron is basing the hero in his new thriller - Codename Enigma - on his dad.

He even introduces his mum in the closing chapter.

Colin, 63, who grew up in Greenock, said: "I see my book as being a way of honouring my late father’s wartime service.

"I expect Codename Enigma to be popular with fans of war fiction and thrillers, as it combines military action with unexpected plot twists.

"I have also taken great care to get all the historical and technical details right."

The eye doctor turned author's second novel follows on from Operation Archer.

In Codename Enigma, leading character Captain Peter Lee is taking part in a hazardous mission to get a captured German Enigma machine out of Tobruk before the port falls to Axis forces in June 1942.

For Colin, it is a real labour of love as he turns from non-fiction to fiction.

He lived in Greenock with his parents and attended Greenock Academy before graduating from Glasgow University Medical School in 1979.

Colin worked in ophthalmology, then ran a nursing home before retraining as a hypnotherapist.

He suffered a very severe heart attack in 2015 and during his recovery he turned to writing from his home in Dunblane.

He now cares for his wife Vivien,who was left disabled following a severe stroke.

His dad worked as a local GP from 1949 until he retired in 1978.

Originally his practice was based in Port Glasgow but in 1968 he set up a new GP partnership in Greenock's Bank Street with Dr Ian Martin and Dr John Kennedy.

His wife Agnes was a consultant ophthalmologist at Greenock Eye Infirmary from 1960-79 and then at Inverclyde Royal Hospital from 1979 until her retiral the following year.

Peter died in 1996 and his wife passed away in April 2014, having spent the last four years of her life in Alt na Craig nursing home in the west end.
