She went back into the passageway of the house, and by the light of a paraffin lamp made her last entry in the little diary she carried.

    "That makes eight we have seen, Thompson," she said to her escort. "Is there anybody else on the list?"

    "Nobody else to-night, miss," said the young man, concealing a yawn.

    "I'm afraid it is not very interesting for you, Thompson," said the girl sympathetically; "you haven't even the excitement of work. It must be awfully dull standing outside waiting for me."

    "Bless you, miss," said the man. "I don't mind at all. If it is good enough for you to come into these streets, it is good enough for me to go round with you."

    They stood in a little courtyard, a cul-de-sac cut off at one end by a sheer wall, and as the girl put back her diary into her little net bag a man came swiftly down from the street entrance of the court and passed her. As he did so the dim light of the lamp showed for a second his face, and her mouth formed an "O" of astonishment. She watched him until he disappeared into one of the dark doorways at the farther end of the court, and stood staring at the door as though unable to believe her eyes.

    There was no mistaking the pale face and the straight figure of Jasper Cole, John Minute's secretary.

 

 

IV. THE ACCOUNTANT AT THE BANK

 

 

    May Nuttall expressed her perplexity in a letter:

 

    DEAR FRANK: Such a remarkable thing happened last night. I was in Silvers Rents about eleven o'clock, and had just finished seeing the last of my patients, when a man passed me and entered one of the houses—it was, I thought at the time, either the last or the last but one on the left. I now know that it was the last but one. There is no doubt at all in my mind that it was Mr. Cole, for not only did I see his face, but he carried the snakewood cane which he always affects.

    I must confess I was curious enough to make inquiries, and I found that he is a frequent visitor here, but nobody quite knows why he comes. The last house is occupied by two families, very uninteresting people, and the last house but one is empty save for a room which is apparently the one Mr. Cole uses. None of the people in the Rents know Mr. Cole or have ever seen him. Apparently the downstairs room in the empty house is kept locked, and a woman who lives opposite told my informant, Thompson, whom you will remember as the man who always goes with me when I am slumming, that the gentleman sometimes comes, uses this room, and that he always sweeps it out for himself. It cannot be very well furnished, and apparently he never stays the night there.

    Isn't it very extraordinary? Please tell me what you make of it—

 

    Frank Merrill put down the letter and slowly filled his pipe. He was puzzled, and found no solution either then or on his way to the office.

    He was the accountant of the Piccadilly branch of the London and Western Counties Bank, and had very little time to give to outside problems. But the thought of Cole and his curious appearance in a London slum under circumstances which, to say the least, were mysterious came between him and his work more than once.

    He was entering up some transactions when he was sent for by the manager. Frank Merrill, though he did not occupy a particularly imposing post in the bank, held nevertheless a very extraordinary position and one which insured for him more consideration than the average official receives at the hands of his superiors. His uncle was financially interested in the bank, and it was generally believed that Frank had been sent as much to watch his relative's interests as to prepare himself for the handling of the great fortune which John Minute would some day leave to his heir.

    The manager nodded cheerily as Frank came in and closed the door behind him.

    "Good morning, Mr. Merrill," said the chief. "I want to see you about Mr. Holland's account. You told me he was in the other day."

    Frank nodded.

    "He came in in the lunch hour."

    "I wish I had been here," said the manager thoughtfully. "I would like to see this gentleman."

    "Is there anything wrong with his account?"

    "Oh, no," said the manager with a smile; "he has a very good balance. In fact, too large a balance for a floating account. I wish you would see him and persuade him to put some of this money on deposit. The head office does not like big floating balances which may be withdrawn at any moment and which necessitates the keeping here of a larger quantity of cash than I care to hold.

    "Personally," he went on, "I do not like our method of doing business at all.
