“That money was a loan, for which she deposited with me a number of diamonds. The diamonds were valued by Mr. Stronge of Hurst & Stronge’s, and I gave her less than their value. I thought I had taken all reasonable precautions, but now,” Mr. Williams made a faint gesture of despair, “now it seems that they were stolen.”

“Stolen?” Mr. Scarlett repeated in a shocked voice. “My dear sir! Allow me to say how extremely sorry I am to have to tell you that I fear your discovery has come too late. Your cheque had been paid practically in full.”

Mr. Williams gave a little groan, though he had evidently been expecting the bad news. He would have spoken, but French broke in with, “Is that so, sir? That is really what we came to ask. Now I want you please to give me as detailed an account of the whole business as you can.”

“I will do so, of course,” Mr. Scarlett returned, “but I fear my story will not help you much.” He raised his desk telephone. “Ask Mr. Plenteous to come here,” he directed, and when a young, fair-haired man had entered he resumed, “This is Mr. Plenteous who carried out the details of the transaction. As Mr. Williams has said, he and the lady called on me,” he turned over the leaves of a diary, “about midday on Thursday, 26th November. He introduced the lady as a Mrs. Chauncey S. Root, of Pittsburg, and stated he had called to certify that she was the person referred to in a cheque he had made out. She produced a cheque for £3000, and Mr. Williams identified it as his. She thanked him and he withdrew. She then said that she wished to open a temporary account, and that she would like cash for £1500, and to lodge the remainder. I sent for Mr. Plenteous, and asked him to arrange the matter, and he showed the lady out to his counter. Next day the balance was withdrawn except for a few shillings, which I believe we still hold. Is not that correct, Plenteous?”

“Yes, sir,” the fair-haired young man answered, “quite correct. I can turn you up the exact balance in a moment.”

“Presently, thank you, Mr. Plenteous,” French interposed. “In the meantime perhaps you would tell us what took place between you and the lady after you left this office.”

After a glance at his chief, the clerk answered:

“Mrs. Root handed me the cheque for £3000, and said she wished to lodge half. I filled the customary forms, took her signature, and gave her a passbook, all in the usual way. Then she told me she would like the other £1500 cashed in notes of small value. She said she was a stranger to London, but that already she had discovered the difficulty of changing Bank of England notes. Being short of ready money, she had proffered a twenty-pound note in a shop. It was refused, and on asking for change in a bank which happened to be next door, the cashier politely informed her he was not permitted to change notes for strangers. She had, indeed, to go back to her hotel before she could get it done. She said she therefore wanted nothing larger than ten pounds, and at her further request I counted her out a hundred tens and a hundred fives. She stowed them away in a despatch case she was carrying. I pointed out that that was not a very safe way to carry so large a sum, but she laughed and said she guessed it was all right, that no one would know she had money in it. She said good-day and went out, and that was the last I saw of her.”

“You noticed nothing in any way suspicious about her manner or actions?”

“Nothing whatever.”
