There was no getting at the truth of the matter. Since she first came to London, four years ago, having been married abroad to her husband, Jack Hargrave, a young man of good family, but a bit of a mauvais sujet, she had made many acquaintances. But she appeared to have no old friends who could throw any light on her real age or her antecedents.

Her husband’s relatives received her with scant cordiality, there was too much reticence about her previous history to incline them in her favour. As a matter of fact, they were not over-fond of Jack himself. There had been certain early episodes in his career which had not endeared him to right-thinking persons.

It was well-known that he was in no sense of the word a wealthy man. Yet he kept an expensive flat, he was always immaculately dressed, and his wife, to judge by her costly costumes, must have had a very liberal allowance.

They entertained a great deal, and they had bridge parties every night when they were at home. Knowing people whispered amongst themselves that it was their winnings at bridge which enabled them to make such a brave show. They were certainly both very skilful players. Not a few persons thought they were a bit too skilful, too uniformly successful.

Two years after their marriage, Jack Hargrave died suddenly of pneumonia, the result of a neglected chill. Strange to say, he left no will. His widow explained this by the fact that he had made all his property over to her, by deed of gift, soon after their marriage, as he did not want her to be burdened with death duties.

Things were not altered in any way by Jack’s death. His widow kept on the expensive flat in Mount Street. When a decent period of mourning had elapsed, she appeared in her usual tasteful costumes, and resumed her bridge parties.

There was nothing to wonder at in this. If Jack Hargrave had made over all his property to her, she was as well-off after his death as before. Rather better, as there was only one to spend the income instead of two.

A certain thing, however, did occur which made some people suspicious. Her husband’s relatives, who had never been more than coldly civil during Jack’s lifetime, now dropped her altogether.

Jack, who was a few years younger than his wife, had been at Eton and Oxford with Guy Rossett, and they were old friends. When Hargrave returned from abroad with his pretty bride, he had hunted up Guy and induced him to become a frequent visitor in Mount Street.

Guy was considerably attracted by the young hostess. Of course, he knew that his friend was looked at askance by many people, and he knew nothing more than the rest about Mrs Hargrave’s antecedents.
