The principal assistant entered: 'Mr. Williams, do you remember on what day it was that Miss Hawtrey selected the two tiaras?' 'It was about three weeks ago, sir; I cannot tell you the exact day without consulting the sales book.' 'Do so at once, if you please.' Mr. Williams went out and returned in a moment with the book. 'It was the 15th of last month, sir--July.' 'You served her yourself, I think, Mr. Williams, or, rather, perhaps you assisted me in doing so?' 'Certainly, sir.' 'What was the value of the tiaras, Mr. Williams?' 'One was twelve hundred, the other was twelve hundred and fifty, sir.' 'She took them away herself?' 'Certainly, sir; I offered to place them in the carriage for her, but she said it was a few doors up the street, and she would take them herself.' 'You have not a shadow of doubt about the facts, Mr. Williams?' 'None whatever, sir,' the assistant said, in some surprise. 'You know Miss Hawtrey well by sight?' 'Certainly, sir; she has been here many times, both by herself, for repairs or alterations to her watch or jewellery, and with other ladies.' 'Thank you, Mr. Williams, that will do at present.' The door closed and the jeweller turned to his customers. Mr. Hawtrey looked confounded, his daughter bewildered. 'I do not understand it,' she said. 'I have not been here, Mr. Gilliat, since the beginning of May, when I came to you about replacing a pearl that had become discoloured in my necklace.' 'I remember that visit perfectly, Miss Hawtrey,' the jeweller said gravely, 'but I must confirm what my assistant has said. Allow me to recall to you that, in the first place, you told me that in view of an approaching event you required a tiara of diamonds, and of course, having heard of your engagement to Lord Halliburn, I understood your allusion, and came in here with you, and had the honour of showing you five or six tiaras. Of these you selected two, and said that you should like to show them to Mr. Hawtrey before choosing. I offered to send an assistant with them, but you said that your carriage was standing a few doors off and that you would rather take them yourself. Our firm having had the honour of serving Mr. Hawtrey and his family for several generations, and knowing you perfectly, I had, of course, no hesitation in complying with your request. I may say, as an evidence of the exactness of my memory, that Miss Hawtrey was dressed exactly as she is at present. I had, of course, an opportunity of noticing her dress as she was examining the goods. She had on that blue walking dress with small red spots, and the bonnet with blue feathers with red tips.' 'Will you give me the hour as well as the day at which you say my daughter called here?' Mr. Hawtrey said sternly. 'My own impression is that it was about three o'clock,' the jeweller said, after a moment's thought. 'Will you call your assistant and ask him?'
