“Twenty times the inducement!” laughed the Professor. “Good arithmetic, anyway! Aye, well, my friend, I don’t think this will do much good. But, as a curiosity, I should like a copy of that bill. Do you think our worthy of the paste-pot and brush would give us one?” “Nothing would please him better, I should think,” said Blick. “Especially if you give him the price of a pint of ale—bill-posting, I believe, is considered to be thirsty work.” The Professor laughed again, and approaching the bill-poster, appropriated a couple of his bills, and handed him half a crown. “Going to stick these things up all over the countryside I suppose?” he asked, as he handed one bill to Blick, and folded up the other for his pocket. “Mean to create a widespread interest, eh?” “Something of that sort, sir,” answered the bill-poster. “Such was my instructions. Two hundred copies of that poster I have in my cart, and up they go before dinner-time, all round this here village. And,” he added with a wink, “a fat lot of good they’ll do!—in my opinion.” “No good, you think?” suggested the Professor. “Why not?” “’Cause that there affair’s a darned sight too deep down in mystery!” said the bill-poster. “Deep, deep, deep—gentlemen! A deed o’ darkness!—and ain’t going to be found out in a hurry. But business is business, and I must go on with mine, which at present is to excite everybody and arouse cupidity and avaricious feelings!” “A humorist!” observed the Professor, as the bill-poster hurried away. He walked on into the village at Blick’s side, looking about him with inquisitive eyes. Suddenly he caught sight of the Sceptre. “Ah!” he said. “So that’s the Inn where the midnight meeting took place? I should like to look in there—I wonder if they could give us some lunch?” “I’m staying there,” replied Blick. “My headquarters. And I’ve a private sitting-room. If you’ll honour me, sir, I’ll order lunch whenever you like—they’re well provided.” The Professor professed himself delighted, and for the next hour or two he and Blick, over the luncheon-table and round the fire, discussed the Markenmore problem in all its ramifications. At three o’clock in the afternoon they went out to examine the scene of the drama, with Markenmore Hollow as a final objective. But as they strolled along the road, Blick suddenly caught sight of Daffy Halliwell, just within the wicket gate of the Dower House—and he saw, too, that Daffy quietly signalled her desire to speak with him. CHAPTER XXIV THE MAN WHO COULD GUESS As she made her signalling movement towards Blick, Daffy retreated a pace or two within the thick shrubbery, and the expression in her eyes indicated a desire for secrecy and caution. Blick, in his turn, signed to his companion to follow him, and whispered an aside as they left the road and passed through the wicket-gate.
