Callender and Perry Callender-Graham was announced on the girl's nineteenth birthday. One night a few months later, and just one week before the day fixed for the wedding, Perry Callender-Graham was found dead in a quiet side street near Riverside Drive. There were no marks of violence on his body, and apparently he had not been robbed. In his pockets were several letters which could have no bearing on the cause of his death, an empty envelope, a sum of money, a jewel-case containing a diamond pendant, probably intended as a gift for his fiancée, and two keys which seemed to be new. Both were latchkeys: one rather large and long, looking as if it might belong to the front door of a house; the other was small, not unlike the key to the door of the dead man's flat. Neither fitted any door of the private hotel in which he lived, however, and consequently suggested mystery. But as three specialists certified death by natural causes, the police came to regard the keys as of no importance. The doctors testified to a condition known as "status lymphaticus," which cannot be diagnosed during life, but which may cause a slight shock to be fatal. It was thought that Callender-Graham—whose body lay close to a street crossing—might have started back to save himself from being run over by a swift automobile suddenly turning the corner, and in the shock of falling have died of heart failure. Grace Callender was grieved and distressed, but not prostrated with sorrow, as she would have been over the loss of an adored lover. Everyone who knew her knew that she had been going to marry her cousin not because she was in love, but in order to give him the fortune wrongfully diverted from his father. In these peculiar circumstances, many people prophesied the thing which happened a year later: her engagement to Ned Callender-Graham, through whom the restitution could equally well be made. He seemed to be a popular fellow, even better liked in general than his dreamy, poetical brother; and as his friends guessed that he had unselfishly stood in the background for Perry's sake, all were pleased with his good fortune. The engagement went on for six months; and then a week before the wedding was to take place, Ned Callender-Graham was found dead in the same street and almost on the same spot where his brother had fallen a year and a half before. This extraordinary coincidence was rendered even more remarkable by the fact that nearly every detail of the first tragedy was repeated in the second. Not only had the brothers met their death in the same street, and almost on the eve of marriage with the same girl, but,
