'The manager will stop them at once. But he says that if the thing was done by an old hand, there must be confederates in it, and there will be trouble. However, the notes are stopped. That's done. Then I went on to the commissionaires' barracks in the Strand. The sergeant very soon found the man, and I had a talk with him. He was employed by an old gentleman, he says, staying at the Cecil Hotel, Strand. The old gentleman sent him to the bank with instructions to get the money in ten-pound notes; and very particular he was with him about not losing any of them on the way. He didn't seem a bit in a hurry either. Took the notes from the man and laid them in a pocket-book. It was in the coffee-room, and half a dozen other gentlemen were there at the same time. But this gentleman seemed alone.' 'Humph! A pretty cool business, upon my word! No hurry about it. Plenty of time. That was because they knew that the old cheque book would not be found and examined.' 'Why did they write the cheque on the counterfoil? Why did they put the cheque book back again--after they had taken it out?' 'I don't know. The workings of a forger's brain are not within the compass of my experiences. Go on, Checkley.' 'The commissionaire says that he is certain he would know the gentleman again.' 'Very good indeed, if we can only find the gentleman.' 'I then went on to the Cecil Hotel and saw the head waiter of the coffee-room. He remembered the commissionaire being sent for: he saw the bundle of bank-notes brought back from the bank, and he remembers the old gentleman very well. Says he should certainly know him again.' 'Did he describe him?' 'There didn't seem anything particular to describe. He was of average height, so to speak, dressed in grey trousers and a black frock-coat, and was grey-haired. Much as if I was to describe you.' 'Oh! The notes are stopped. Yet in three weeks there has been ample time to get them all changed. Every note may have been changed into gold in three weeks. An elderly gentleman: grey hair: average height: that tells us nothing. Checkley, the thing has been done by some one who had, or still has, access to my safe. Perhaps, in some way or other, keys have been procured. In that case----' He stepped over to the safe and opened a drawer. 'See, Checkley; this drawer is untouched: it is full of jewellery and things which belonged to my mother. Nothing touched. Here is a bag of spade guineas again--nothing taken. What do you say to that? If the forger had possessed keys, he would, first of all, have cleared out the things which he could turn into money without any difficulty and very little risk. Nothing taken except that cheque, and the cheque book replaced. What do you say to that? Eh?' 'I don't know what to say. I'm struck stupid. I never heard of such a thing before.'
