individual, and if you extend the time period too many days, you might find there is ongoing, permanent dysfunction in the individual patient. the answer is it varies upon so many factors. 0k, we must leave it there. thank you for joining us. a bbc news investigation has found that a third of all the stock at one sea life centre died in the space of a year. the owners merlin entertainments has described the loss of 800 creatures as "deeply regrettable" and "distressing." it blamed a water quality issue. the marine conservation society says it's now reviewing its sponsorship of the centres. alex dunlop has this exclusive report. sea life centres are among the best—known visitor attractions where you can see everything close—up, from the exotic to the more familiar. the emphasis is on

education and conservation. gary and jenny smith are taking their granddaughter to the sea life centre in great yarmouth. we wouldn't come on our iron but you do learn a fair bitjust on our iron but you do learn a fair bit just walking around. on our iron but you do learn a fair bitjust walking around. it is good in that respect. a bbc investigation of sea life's own figures reveals high death rates among its stock with big differences between eight centres in england. of around 2a,000 creatures, more than centres in england. of around 2a,000 creatures, more than 4,000 died between 2015—16. at its london aquarium, one in ten died in one year. at great yarmouth, one in three died. ben is a well—known biologist and ambassador for the conservation society. 0ne biologist and ambassador for the conservation society. one in three creatures dying is not acceptable. you wouldn't go to hospital and expect to die one in three times. i wouldn't and it isn't acceptable that a whole facility can lose a

their procedures to see if there is scope to tighten them up. perhaps also for those who inspect those sea life centres perhaps to go back and have another look. hidden beneath the waves, there are creatures beyond our imagination. during conservation is a huge issue, thanks in part to be busy‘s bloop planet. in. part fnhfipgqfsfilwflm was a spike in. part fnhfipgqfsfilwflm 7333555339 was 7 it says it aims . provide best ca re but highi—éi? but high death 77 "7 7' some centres - come as a shock in some centres may come as a shock to the millions who visited them. now it's time for meet the author. this week on meet the authorjim naughtie talks with the writer mc sergeant hamish macbeth lives in a sleepy place, lochdubh, in the highlands where you might think there's not much drama. but 33 books on, he's investigating yet another murder in death of an honest man. yet, in mc beaton's novels, even when dastardly

happenings are all around you, the pace of life in lochdubh, with its regular cast of characters never seems to change. these are crime stories that are written to be reassuring. welcome. what do you think hamish macbeth's secret is? ithink... what fascinates people is he's totally unambitious. and what i try to do, you see, i think of myself more as an escape artist than a writer, is give someone something to take their mind off the troubles or a wet day or a journey. and it's based on a crofter that i still know up near buey, and he would say, "just fed the hens and i'm going to see my cousin in hong kong."

and very laid—back. fascinating. yes, it is interesting. of course, he doesn't want to leave lochdubh, which is a lovely place, although terrible things keep happening. and he's terrified. inspector blair, who keeps interfering with him and his activities, is always a threat on the horizon but all he wants to do is stay with his own folk in the village and that's a very reassuring thing to readers, isn't it? yes, it is. it observes the unity, keeping it all in a small place, and justice seen to be done. i admit it's rather old—fashioned because it can't be high—tech. the forensic lab's usually off playing shinty or drunk. but it's reassuring to know that it will all come all right in the end. i like stories with happy endings. you do, clearly. and there is also a great calm in the way that you write. there's no sense of hurry or frenzy, even when awful things are happening.

there will be a moment of violence, we're not going to give away the plot because that would be a terrible thing to do,
