'Excuse me a moment,' said the shopkeeper, and he followed the young man into the private office.

As I examined the curious heterogeneous collection of things for sale, I heard the clink of coins being poured out on the lid of a desk or an uncovered table, and the murmur of voices floated out to me. I was now near the entrance of the shop, and by a sleight-of-hand trick, keeping the corner of my eye on the glass pane of the private office, I removed the key of the front door without a sound, and took an impression of it in wax, returning the key to its place unobserved. At this moment another young man came in, and walked straight past me into the private office. I heard him say,—

'Oh, I beg pardon, Mr. Simpson. How are you, Rogers?'

'Hallo, Macpherson,' saluted Rogers, who then came out, bidding good-night to Mr. Simpson, and departed whistling down the street, but not before he had repeated his phrase to another young man entering, to whom he gave the name of Tyrrel.

I noted these three names in my mind. Two others came in together, but I was compelled to content myself with memorising their features, for I did not learn their names. These men were evidently collectors, for I heard the rattle of money in every case; yet here was a small shop, doing apparently very little business, for I had been within it for more than half an hour, and yet remained the only customer. If credit were given, one collector would certainly have been sufficient, yet five had come in, and had poured their contributions into the pile Summertrees was to take home with him that night.

I determined to secure one of the pamphlets which the man had been addressing. They were piled on a shelf behind the counter, but I had no difficulty in reaching across and taking the one on top, which I slipped into my pocket. When the fifth young man went down the street Summertrees himself emerged, and this time he carried in his hand the well-filled locked leather satchel, with the straps dangling. It was now approaching half-past five, and I saw he was eager to close up and get away.

'Anything else you fancy, sir?' he asked me.

'No, or rather yes and no. You have a very interesting collection here, but it's getting so dark I can hardly see.'

'I close at half-past five, sir.'

'Ah, in that case,' I said, consulting my watch, 'I shall be pleased to call some other time.'
