“There’s another thing I should like to know,” he said, “and that is how you have learned all this. I suppose you won’t tell me?” Speedwell smiled as he shook his head. “Some day, sir, when the case is over. You see, if I were to show you my channels of information you would naturally use them yourself, and then where should I come in? A man in my job soon learns where to pick up a bit of knowledge. It’s partly practice and partly knowing the ropes.” “And there’s another thing I wish,” Cheyne went on as if he had not heard the other, “and that is that you had gone a bit further in your researches and learned what that paper was and what game that gang is up to.” The detective’s manner became more eager. “That’s what I was coming to myself, Mr. Cheyne. If you want that information I can get it for you. But it may cost you a bit of money. It would depend on the time I should have to spend on it and the risks I should have to run. If you would like me to take it on for you I could do so. But of course it’s a matter for yourself altogether.” Cheyne reflected. This Speedwell had certainly done an amazing amount of work already on the case, and his success so far showed that he was a shrewd and capable man. To engage him to complete the work would probably be the quickest way of bringing the matter to a head, and the easiest, so far as he himself was concerned. But then he would lose all the excitement and the fun. He had pitted his wits against these men, and to hand the affair over to Speedwell would be to confess himself beaten. Moreover, he would have to admit his failure to Miss Merrill and to forego any more alarms and excursions in her company. No, he would keep the thing in his own hands for the present at all events. He therefore said that he was obliged for the other’s offer, which later on he might be glad to accept, but that for the moment he would not make any further move. “Right, sir. Whatever you say,” Speedwell agreed amicably. “I might add what indeed you’ll be able to guess for yourself from what I’ve told you, that this crowd is a pretty shrewd crowd, and they’ll not, so to speak, be beating the air in this job of yours. They’re going for something, and you may take it from me that something will be worth their going for. At least, if not, I’ll eat my hat.” “I quite agree with you,” Cheyne returned, fumbling in his pocket. “It now remains for me to write my check and then we shall be square.” Cheyne counted the hours until four o’clock, and as soon as he dared he set off for No. 17 Horne Terrace. Indeed, he timed his visit so well that as he reached the top of the tenth flight of steps, the door of room No. 12 opened and the model emerged. She held the door open for him, and ten minutes later he was seated in the big armchair drinking the usual cup of fragrant China tea.
