the crop has an estimated street value of more than a million pounds. officers say the plants were being grown in twenty large rooms with almost every part of the bunker dedicated to what they described as the "wholesale production" of cannabis. six men have been arrested. jon kay reports. hidden in the wiltshire countryside, rghq chilmark, a huge underground bunker built to protect britain's leaders in a nuclear war. if we go in here, mind your head... this afternoon, police showed us the vast cannabis growing operation they uncovered here overnight. how would you describe what you have discovered here? a huge, massively professional setup, the biggest cannabis factory farm i have seen in 25 years of service. to find this in the heart of rural wiltshire is quite incredible. police found 20 large rooms filled with plants and equipped with specially installed equipment. every room has got this set up in it, the venting at the top to withdraw the fumes, take that outside, contain the heat. officer says huge amounts of power have been secretly siphoned off the national grid here. in several rooms, you see signs of people sleeping and working here. this was the old canteen, still being used last night, it seems, years after the bunker was sold off by the ministry of defence. six men were arrested, three of them on suspicion of human trafficking offences. in this room, police have found hundreds of bags of old compost, and they suggest the bunker has been used for cultivation for months. this is what the bunker looked like when it was filmed by the bbc during the cold war, with walls almost two feet thick police described it as almost impenetrable. they have been monitoring the site for some time and swooped when they saw the doors opening last night. they say local people had reported suspicious activity and a powerful smell coming from the vents. jon kay, bbc news, wiltshire. the headlines. storm doris brings widespread disruption and damage to parts of the country, with gusts of wind up to 95 miles per hour recorded. there have been long delays for train passengers as hundreds were stranded at london's euston station as lines to the north west were blocked. a woman was killed in wolverhampton when a large piece of wood was blown from the roof of a building in the city centre. premier league champions leicester city have sacked their manager claudio ranieri. he led them to the top of the league just nine months ago. net migration to the uk has fallen below 300,000 for the first time in two years. it's still above the government's target figure. now it's time for meet the author. sara baume has written a novel that deals with one of greatest contemporary problems, the feeling of loss, maybe hopelessness, among young people who think that the opportunity they'd been brought up to believe in is an illusion. her book a line made by walking uses artwork as a structure. she was an art student herself in ireland and the story is told by the narrator frankie, who struggles with mental illness and sees little hope. it's a dark story but a compelling one. welcome. the theme of this story is a problem, i suppose, that's very, very familiar and troubling to many people at this moment. yeah. i think we live in an age when people grow up much slower. definitely my generation. it's funny, i think about this quite often now, my parents were married and having kids at my age. but it's totally acceptable that in your early 30s you're still... i'm still doing exactly what i did as a child only, i'd like to think, a slightly more sophisticated version. i've had some wonderful responses from parents. that's interesting. yeah. saying that they're going to give this book to their kids, presumably to help them! but their kids in their 20s. how do you think it might help them? i suppose only to know that you're not the only person who feels like this. i think it's something i touch on in the book without passing any judgment, frankie, the narrator, feels very lost and disilussioned in a quite normal way because society is set up to make us feel our lives are incomplete and that this is a problem. to what extent is there an autobiographical element? to a great extent. it started actually with a nonfiction essay that i wrote when i was in college and it was structured around photographs of dead animals that i was taking, the idea that this character is stranded in the irish countryside, feels very lost and alone and feels as though everything is dying and nature becomes a kind of metaphor for that. she notices... it's like the way when you're pregnant, not that i've ever been pregnant, but you suddenly see people who are pregnant, keep seeing women who are pregnant. she keeps finding these dead animals because she notices them, i suppose. that builds the landscape around her. you were an art student and the visual arts are very important to you, you see the world in a sense through that artistic lens. it's interesting that you use artwork as a framework for the story. did thatjust come naturally? it did because i suppose it came out of the character's own mind. she's a former art student who is struggling to be an artist and she is concerned that now that she's finished formal education she won't learn anything any more and so she's getting herself on the artworks that she knows and at the same time trying to find meaning for her life in the only way she knows how, through examining artworks. it's a strange idea, really, isn't it, that learning stops when formal education ends because it should actually be the other way round and we should all know that and understand it and look forward to it. learning through life. yeah, that's most jobs, yeah, that's mostjobs, they result in an ending of that. i am very covered by the fact that i graduated during the irish recession. i think it's still a problem in irish society, we are all qualified but there are so few opportunities. you end up in dead—end jobs and learning in. frankie has all kinds of problems and you touch on something thatis problems and you touch on something that is on many people's mind, the prevalence of mental illness of various kinds, for which there is no immediate help, not much prospect of escape. more aware of that now rv?” suppose we are. we grow up slower and we are more lost and disillusioned. there is no medication for that, which is the easiest way. i don't stand in judgment of the people that take mitigation. frankie is very resista nt. mitigation. frankie is very resistant. the book draws to a certain conclusion and it's for the reader to decide whether she was right to be resistant or not. what do you think of frankie? rewriting this book recently, it grew from the essay that i wrote when i was 2526, rewriting it recently there were so many things that restricted me about her and many things that restricted me about herandl many things that restricted me about her and i was tempted to cut because i don't think like that any more. then i realised that this is my 25—year—old self. then i realised that this is my 25-year-old self. you have to v herself. precisely. she needs to make our own mistakes without you intervening. yes, she needs for people to decide for herself. what did it tell you about your 25—year—old self, rewriting this?” was very self absorbed and i think thatis was very self absorbed and i think that is a sign of the times. different perspective. the big deal isa different perspective. the big deal is a lot with the death of the grandmother. at the time, i was interested in tackling that. i am still interested in that. we don't use much about grandparents. since the book, in the last year, my father died. that was a huge dissertation. they said that you do not fully grasp and tell you one of your parents dies. i made a huge shift in that time period myself. frankie seems very small and the eagle is very important. i think you need a bit of ego if you're going to push or the arts. do you think that people are more alone and they have to be self reliant if they will make their way? yes, i sense a writer both lonely character. that is what interests me and it is an endless subject. —— yes, i tend to write about lonely characters. this is a book about the loneliness of failure oi’ book about the loneliness of failure or the loneliness of having received that you have failed when really your life has hardly begun. —— of having received that you have failed. would you like people to feel more optimistic about life when they finished the book?” feel more optimistic about life when they finished the book? i hope that they finished the book? i hope that the artworks will. .. they finished the book? i hope that the artworks will... love them. well, let them in a way or get people to look at smaller details more closely. if that were you find yourselves?
