From the big volume I detached the loose leaf, dated 1893, which recorded Lord Semptam's purchase of a carved table for fifty pounds, and on which he had been paying a pound a week from that time to the date of which I am writing, which was November, 1896. This single document taken from the file of three years previous, was not likely to be missed, as would have been the case if I had selected a current sheet. I nevertheless made a copy of the names and addresses of Macpherson's present clients; then, carefully placing everything exactly as I had found it, I extinguished the gas, and went out of the shop, locking the door behind me. With the 1893 sheet in my pocket I resolved to prepare a pleasant little surprise for my suave friend Macpherson when he called to get his next instalment of five shillings.
Late as was the hour when I reached Trafalgar Square, I could not deprive myself of the felicity of calling on Mr. Spenser Hale, who I knew was then on duty. He never appeared at his best during office hours, because officialism stiffened his stalwart frame. Mentally he was impressed with the importance of his position, and added to this he was not then allowed to smoke his big, black pipe and terrible tobacco. He received me with the curtness I had been taught to expect when I inflicted myself upon him at his office. He greeted me abruptly with,—
'I say, Valmont, how long do you expect to be on this job?'
'What job?' I asked mildly.
'Oh, you know what I mean: the Summertrees affair.'
'Oh, that!' I exclaimed, with surprise. 'The Summertrees case is already completed, of course. If I had known you were in a hurry, I should have finished up everything yesterday, but as you and Podgers, and I don't know how many more, have been at it sixteen or seventeen days, if not longer, I thought I might venture to take as many hours, as I am working entirely alone. You said nothing about haste, you know.'
'Oh, come now, Valmont, that's a bit thick. Do you mean to say you have already got evidence against the man?'
'Evidence absolute and complete.'
'Then who are the coiners?'
'My most estimable friend, how often have I told you not to jump at conclusions? I informed you when you first spoke to me about the matter that Summertrees was neither a coiner nor a confederate of coiners. I secured evidence sufficient to convict him of quite another offence, which is probably unique in the annals of crime. I have penetrated the mystery of the shop, and discovered the reason for all those suspicious actions which quite properly set you on his trail. Now I wish you to come to my flat next Wednesday night at a quarter to six, prepared to make an arrest.'
