"Her Royal Highness held my great-uncle in much esteem, Mr. Colwyn," she added, as she proceeded to fit one of the keys into the box. "He was one of the most famous of Nelson's captains. When he died the residents of his native town erected a memorial to him. It was inscribed with testimony to his worth in a civic, military, and Christian capacity, together with a text stating that he caused the widow's heart to sing for joy. Beneath the text was commemorated his feat in sinking the French frigate L'Équille, with every soul on board."
"That hardly seems like causing the widow's heart to sing for joy," commented Musard.
"The reference was to English widows, Vincent," replied Miss Heredith, proceeding to open the box with loving care. "At that period of our history we had not discovered the good qualities of the French people, which have endeared them to—Oh!" Miss Heredith broke off with a startled exclamation as the lid of the silver box fell back, revealing an empty interior.
It is only in moments of complete surprise that the human face fails to keep up some semblance of guard over the inmost feelings. At the discovery that the jewel-case was empty Miss Heredith's dignity dropped from her like a falling garment, and she stared at the velvet interior with half-open mouth and an air of consternation on her face.
"Oh!" she cried again, finding voice after a moment's tense silence. "The necklace is gone."
"By heaven, this is amazing," muttered Musard.
"I thought you said it was safe?" The speaker was Phil. He did not look at his aunt as he uttered this reproach, but gazed at the empty box with glowing eyes under drawn brows.
"Phil, Phil, I thought it was safe—oh, I thought it was safe!" cried Miss Heredith almost hysterically. "Where is it gone? Who could have taken it? The box was locked when we saw it upstairs, and the day after the funeral I found Violet's keys at the back of the drawer where she always kept them."
"The box may have been locked when you found it, but it seems equally certain that it was also empty," said Colwyn. He alone of the excited group was cool enough to estimate the awkward possibilities of this discovery. "How was it that the detectives did not open the jewel-case on the night of the murder, so as to make quite sure that the necklace had not been stolen?"
"I took the necklace downstairs and locked it away before the police arrived," said Miss Heredith tearfully. "When Detective Caldew came he asked me if anything was missing from Violet's bedroom, and I told him no. Of course, I did not dream of anything like this. Oh, how I wish now that I had opened the jewel-case at the time. But I never thought. I tried the case and found it locked, so I thought it had not been touched."
