Love on the Train
CORRIDOR CAR DON JUAN
Not even notorious Bluebeards like Landru had so many fiancées to their discredit as the
police credit Desire David, the Don Juan of the corridor cars. Deeming himself irresistible to the opposite sex,. ex-Lieut Desire David, wounded war hero, suspected spy, and six times convicted rogue, who has served twelve years in prison, is once more in the hands of the French police, and the allegations are of an amazing character.
It is alleged that for years David has haunted the corridors of the international trains seeking out wealthy foreign women travelling alone, with the object of making lightning love to them in order to gain their confidence as preliminary to extracting money and jewellery from them. So rapid and so thorough were the methods of the man that he has been known to board a train at the Gare deLyon in the wake of an utter stranger, and to emerge with her at the end of the journey an engaged couple! In one instance it is alleged that he actually went through a marriage ceremony with one of the women he wooed in the course of the journey, taking advantage of a long wait at a frontier station.
He has wooed and become affianced to at least one hundred women, several of them English, and one at least well known in London Society. The man had a: accomplices his sister, and his 'petite Amie. 'who are accused of having helped him to pick out likely victims, and if necessary to aid the main gaining the confidence of these victims ,,,, [missing text]
'Everything has gone wrong between me and my friend' she wrote. ‘I am hopelessly In love with him and life is not worth living. ‘One of these letters sent other lover, and all of them are now in the hands of the police. It was through her sister. Mrs. Mabel Scott, that the
tragedy was discovered. She received a letter and, bursting open the door of the Sat, found Mrs. de Brevai dead in bed. She had garbed herself L her oesi pink silk nightdress, and a oiueboidoir cape covered her shoulders. On her face was a peaceful smile, and she appeared to be staring up at the photograph of the man she loved, hanging on the wall above, as if her last earthly thoughts had been of him before she passed out into eternity. . ? .
Mrs. de Brevai spent a fortune of £10,000 in the last three years, she was separated from a wealthy husband who generously provided for her. Known as Peggy Croshie to the habitués of the West End nightclubs, she would sometimes invite a number of her friends to her other flat in Colville Gardens, Notting Hill Gay, luxurious affairs these parties were, in which no expense was spared. Choice foods and wines were on the table, and champagne flowed like water. The revelry reached high pitch on occasions, and many of her neighbours would chaff her in a friendly way about the noise her friends had made on the previous night, She kept her tiny flat in Dovsr street simply as a handy spot where she could take her friends for cocktails, and she also had a cottage at Virginia Water, which she visited at week-ends. 'We knew bar friend was very wealthy,' explained a male acquaintance, who had often been to her parties, 'but though we met him often at the flat, she introduced him simply As 'Bob'.'
On a night just before the tragedy she met the young banker and implored him to have half an hours talk with her. He was unable to grant this, and she said that she could not go on without him. She also tried to get in touch with him by telephone. Then she wrote just before she died, saying there was nothing more to live for. Not even the gaiety she loved would compensate for the loss of her handsome banker. Mrs. de Brevai left a request to be buried in her wedding dress, and arrangements were made to carry out her wishes.
