In response Miss Heredith related to the detective all that had passed between the young wife and herself in the bedroom before dinner on the night of the murder. Colwyn listened attentively, with a growing sense of hidden complexities in the crime revealed at the eleventh hour. He saw that the case took on a new and deeper aspect when considered in conjunction with the facts which had been so innocently ignored. When Miss Heredith had finished, he asked her when it was first decided to send the necklace to London for resetting. "It was the night before the murder," Miss Heredith replied. "Sir Philip suggested that Violet should wear the necklace to the dance on the following night, but Violet said that the pearls were really too dull to be worn. Mr. Musard agreed with her, and offered to take it to London and have it cleaned and reset by an expert of his acquaintance. Mr. Musard had to return to London on the morning after the dance, so that was the reason why I went into Violet's room before dinner on the night of the party to ask her for the necklace." Colwyn considered this reply in all its bearings before he spoke. "The best thing I can do is to return to London without delay and bring these additional facts before Scotland Yard," he said. "They have been misled--unwittingly but gravely misled--and it is only right that they should be informed at once. I know Merrington, and I will make a point of seeing him personally and telling him about the discovery of the missing necklace." The little group heard his decision in a silence which suggested more than words were able to convey. It was Phil who finally uttered the thought which was in all their minds: "Are you satisfied that Hazel Rath is innocent?" "I cannot say that," responded the detective quickly. "The loss of the necklace does nothing to lessen the suspicion against her unless it can be proved that she had nothing to do with its disappearance--perhaps not even then. But all the facts must be investigated anew. The necklace must be traced, and the point about the revolver cleared up. But there is nothing more to be done here at present. The field of the investigation now shifts to London. I will get ready for the journey, if you will excuse me." "I hope you will continue your own investigations, Mr. Colwyn," said Phil earnestly. "I am more than ever convinced of Hazel Rath's innocence, but I have small faith that the police are likely to establish it--even if they attempt to do so. I was not impressed with the skill of Detective Caldew, or his attitude when I told him that I believed Hazel Rath to be innocent." "I will continue my investigations in conjunction with Scotland Yard, if it is your wish," the detective replied. CHAPTER XVIII
