Gilliat took the letter, glanced at it, and then at Dorothy. 'I do not quite understand,' he said doubtfully.

'Not understand?' Mr. Hawtrey repeated with some irritation. 'Do you mean to say that Miss Hawtrey has been supplied with two diamond tiaras?'

'Would you mind stepping into my room behind, Mr. Hawtrey?' the jeweller replied, leading the way into an inner room. As he closed the door his eye met Dorothy's with a look of inquiry, as if asking for instructions. Hers expressed nothing but surprise. 'Am I to understand, Mr. Hawtrey,' he asked gravely, after a pause, 'that Miss Hawtrey denies having received the tiaras?'

'Certainly you are,' Mr. Hawtrey said hotly, 'she knows nothing whatever about them.'

The jeweller pressed his lips tightly together, thought for a moment, and then touched a bell on the table. An assistant entered. 'Ask Mr. Williams to step here for a moment.'

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.'
