William Hickey . jockey judge will ride on circuit . Mr Justice Diplock , a 53-year-old Queen &apos;s bench division judge , is setting out on Circuit on April 15 despite the pleas of his wife , Lady Diplock . Circuit , I should add , is the name of his trusted mount in the bar point-to-point . and Sir Kenneth Diplock , who has ridden in it - and lost - as a Q.C , will be taking part for the first time as a high court judge . his wife views the undertaking with some trepidation . at their home in the Temple last night she told me : Circuit is getting old and though my husband rides him every week with the Cottesmore hunt I do hope he will not ride him next month . I do n&apos;t want him to get hurt again . but no doubt Lady Diplock recalls an accident in 1957 when her husband &apos;s horse fell and he was badly thrown . his arm was broken and later he presided at the Old Bailey with his arm in a sling , hidden under his robes . actually , for any young barrister who wants to have a few modest shillings on the judge , I am told he is a brilliant rider . he will be racing against five barristers . New Zealand &apos;s greatest fighter ace , group Captain Alan ( Lucky ) Deere , who destroyed 21 enemy aircraft during the war , has been appointed aide-de-camp to the Queen in place of group Captain H E Brufton , who is retiring from the R.A.F . Deere , who is 43 and married with two children , is at present deputy director of personnel ( air ) at the air ministry . work again . Charmian Scott , 18-year-old niece of the Duchess of Gloucester , returned to modelling yesterday for the first time since the car accident that put her in hospital four weeks ago . a fast disappearing scar on her left leg , and a slightly discoloured eye - well-camouflaged by make-up - were the only visible reminders of the accident , which occurred when a car in which she was travelling overturned at Hyde Park Corner . I still have one or two other bruises , said Miss Scott , but fortunately they can n&apos;t be seen by the public . she was appearing in a fashion show put on by a Piccadilly firm in a Park-lane hotel . among those watching her were her mother , Lady George Scott , and her elder sister , Georgina , who is a sales-girl for the firm . Georgina does not envy her sister &apos;s much photographed fame . I &apos;m honest with myself , she said with a smile . I know perfectly well that I have n&apos;t got the shape for modelling . so I just sell the clothes she models . separate . the German Ambassador , Dr Hans von Herwarth , has left London to go ski-ing in the Italian Alps . his wife left on the same day for winter sports in southern Germany and the Tyrol . said a spokesman for the ambassador yesterday : they usually take their winter holidays separately . no special significance in that . the ambassador seems to prefer Italy to Austria . I suppose it is just one of those things . pioneering spirit is still there . Dorothy , Lady Bruntisfield , who left England to farm in Kenya 10 years ago , has returned to this country . she has bought a house in Belgravia , and hopes to move in after Easter . when she left England in 1951 she said that Kenya was a country of freedom , wonderful climate and no restrictions . she remained on her farm - a lone white woman - throughout the Mau Mau troubles . I was frightened , of course - who would n&apos;t be ? - but there was something worth fighting for , she told me yesterday . things are different now . we have been let down . and with all these African politicians making trouble it might blow up into another Congo any day . Lady Bruntisfield - first wife of Lord Bruntisfield - sold everything before leaving Kenya . Lady Bruntisfield , in her late fifties , still retains the pioneering spirit . I find building a new home again rather exciting . it &apos;s a challenge you know . and I like a challenge . drawback . Katharine Worsley , the Duke of Kent &apos;s fianc&amp;eacute;e , made her first public appearance with the Queen in a theatre outing last night . and unwittingly , poor girl , she committed a minor social sin . her deep red dress , I &apos;m told by the women with an eye for these things , clashed with the Queen &apos;s black and plum sequined dress . she also discovered one of the drawbacks of royal protocol : she was n&apos;t able to sit with her fianc&amp;eacute; . the Duchess of Kent sat between them . also in the party were Prince Philip and Princess Alexandra . the play at the Vaudeville Theatre ? appropriately the bride comes back . old boys . one of London &apos;s odder reunions took place last night . Herr Reinhold Eggers , a former German schoolmaster who was the security officer at Colditz Castle , the camp for important prisoners of war , met up with some of his old boys . he had dinner with group Captain Douglas Bader at his London mews house . I had tea occasionally with him at Colditz , said Herr Eggers urbanely . I always admired his spirit . earlier I had joined him and Pat Reid , the British escape officer at Colditz , for a drink in a Knightsbridge pub . Herr Eggers has a sense of humour but has never , apparently , lost his schoolmasterly sense of pained surprise that his boys did not abide by the rules . now Reid , he said , was one of my biggest headaches . when he escaped I was hauled over the coals and almost wished I had escaped with him . the habit of Reid &apos;s which Eggers found most infuriating was when he sat in his punishment cell blowing derisive blasts of his trumpet during roll call . I can n&apos;t understand Lord Harewood &apos;s interest in music after Reid &apos;s performance . the Earl of Harewood was another of his prisoners . a splendid fellow , said Eggers . cooking . pretty 24-year-old Vanessa Marsh , whose father , Mr Marcus Marsh , trained horses for the late Aga Khan , has deserted the heaths of Newmarket for the kitchens of the officers &apos; club at Catterick Camp . she lives in as a &amp;pound;6 10 s-a-week assistant cook , preparing lunch and dinner for the officers . Vanessa , who two years ago was to be seen dancing with Mr Martin Parsons , half-brother of Mr Antony Armstrong-Jones , tells me : I got tired of riding horses and wanted a change . and I &apos;d taken a cookery course . landlord . from the juke box Elvis Presley throbbed are you lonesome tonight ? and on the table-tennis table the portly gentleman in baggy tweeds finished his game with an adroit smash which landed the ball smack in the face of his 16-year-old shop-assistant opponent . the Duke of Norfolk , Earl Marshal of England , in slightly unaccustomed surroundings , was opening a new coffee bar at the Arundel youth club last night . the club has 80 members and two rules : no credit and no obscene language . and since the duke is the landlord of the building ( rent 1 s a year ) he was the obvious choice as guest of honour . the duke obviously enjoyed his table tennis ( we have a table at the castle and I play with the children ) , but Presley left him unimpressed . I am a bit old , he explained almost apologetically , for that sort of thing . Princess &apos;s new house gets &amp;pound;70,000 refit . that &apos;s an end to all those rumours about jobs in the commonwealth for Princess Margaret and Mr Antony Armstrong-Jones . after all , no one - not even the ministry of works - spends &amp;pound;70,000 on doing up a house if the occupiers are about to go abroad for a few years . it is clear that the Princess and her husband are settling down in London and for this purpose 1a , Kensington Palace ( above ) is well suited . the house , in the south wing of Clock Court , is one of Sir Christopher Wren &apos;s finest examples of domestic architecture . it was built about 1690 . the front door leads out into the court , giving the couple far more privacy than they have at no 10 . it will take 18 months to put no 1a in habitable order . it suffers from bomb damage , dry rot , bad plumbing , and inefficient heating . the money to be spent on Princess Margaret &apos;s new home is only a fraction of a &amp;pound;360,000 plan to give the royal family and their staffs up-to-date accommodation . William Hickey . now young Mr Clore heads for the top . Mr Charles Clore , the Whitechapel tailor &apos;s son who , by his own ability , has become Britain &apos;s best-known man of property , seems to have passed some of his own brilliance on to his son . at an age when most schoolboys are merely preparing for the G.C.E , 16-year-old Alan Evelyn Clore has been accepted for Lincoln College , Oxford . a fairly remarkable achievement , but I am told that young Clore has a very lively mind . his school friends at Le Rosay School in Switzerland ( the old boys include the Duke of Kent , the Shah of Persia , and the Aga Khan ) describe him as a very likeable lad . he has been admitted to Lincoln College without taking an examination because , I am told , his school work was so outstanding . a spokesman for the college says : he has been accepted as a commoner for the academic year beginning in 1962 . Mr Clore adds the information , proud as any parent would be , that his son will study philosophy , politics , and economics . after taking his degree he will read for the bar . Mr Clore &apos;s marriage to his French-born wife Francine was dissolved in 1957 . their two children Alan and his sister Vivien , who is two years younger , were made wards of court in the previous year . there have been suggestions recently of a reconciliation . Mrs Clore , who lives in Paris , is at the moment staying in London . but Mr Clore describes the stories as a lot of nonsense . and his ex-wife tells me her visit is to shop and see her doctor and dentist . flying out . nine-year-old Christina Onassis , daughter of Mr Aristotle Onassis and his ex-wife Mme Tina Livanos , left England for Paris yesterday after a few days in Oxford where she has been visiting her mother , who is in hospital recovering from a ski-ing accident . Christina was driven from Oxford to London Airport in a grey Jaguar - accompanied by her nanny , Miss Lehane . at the airport they went aboard the aircraft an hour before the other passengers . wanted : a star . Madame Lily Payling , the Australian contralto who many times packed the royal Albert Hall before the war , is looking for a British singer to make into a star . Mme Payling , who now teaches in London , started the Payling musical society after the war . through it she encouraged many an unknown singer from obscurity to concert status . qualifications required , apart from a good voice ? patience and a lot of hard work , she said last night . golf bargain . it is an object lesson in the concessions one has to make after marriage . former Wimbledon champion Budge Patty marries on April 5 in Switzerland when some of his London friends will be flying out there . at 36 he is giving up full-time tennis , but fears that he will still be too good to be given a game by his wife . and his 26-year-old fianc&amp;eacute;e Macina Sfezzo who has lived most of her life in Switzerland is an expert skier - far better than Patty is likely to become now . so they have struck a bargain . both have started to play golf . Patty got the idea when he was given a set of clubs for a wedding present . to his surprise he has discovered that although he plays tennis right-handed he plays golf left-handed . Cavanagh designs for Katharine . John Cavanagh , the crinkle-faced Irishman who started his career picking up pins in a Paris salon and is now London &apos;s leading couturier , has been chosen by Katharine Worsley to design her wedding-dress of the year for her marriage to the Duke of Kent . said Cavanagh , 46 and for years the favourite designer of Princess Alexandra and the Duchess of Kent : this is one of the most thrilling things that has happened to me since my shop opened nine years ago . Mr Cavanagh has already met Miss Worsley at Kensington Palace to talk over ideas .
