"What is it?" asked Purdie.
"This," replied Ayscough. "A Praed Street tradesman—in a small way—was picked up, dying, in a quiet street off Maida Vale, at twelve o'clock last night, and he died soon afterwards. And—he'd been poisoned!—but how, the doctors can't yet tell."
CHAPTER THIRTEEN
THE CALL FOR HELP
Purdie, whose temperament inclined him to slowness and deliberation in face of any grave crisis, motioned the detective to take a seat in the quiet corner of the smoking-room, into which they had retreated, and sat down close by him.
"Now, to begin with," he said, "why do you think this affair is connected with the affair of the old pawn-broker? There must be some link."
"There is a link, sir," answered Ayscough. "The man was old Daniel Multenius's next door neighbour: name of Parslett—James Parslett, fruit and vegetable dealer. Smallish way of business, but well known enough in that quarter. Now, I'll explain something to you. I'm no hand at drawing," continued the detective, "but I think I can do a bit of a rough sketch on this scrap of paper which will make clear to you the lie of the land. These two lines represent Praed Street. Here, where I make this cross, is Daniel Multenius's pawnshop. The front part of it—the jeweller's shop—looks out on Praed Street. At the side is a narrow passage or entry: from that you get access to the pledge-office. Now then, Multenius's premises run down one side of this passage: Parslett's run down the other. Parslett's house has a side-door into it, exactly opposite the door into Multenius's pledge office. Is that clear, Mr. Purdie?"
"Quite!" answered Purdie. "I understand it exactly."
"Then my theory is, that Parslett saw the real murderer of Daniel Multenius come out of Multenius's side-door, while he, Parslett, was standing at his own; that he recognized him, that he tried to blackmail him yesterday, and that the man contrived to poison him, in such a fashion that Parslett died shortly after leaving him," said Ayscough, confidently. "It's but a theory—but I'll lay anything I'm not far out in it!"
"What reason have you for thinking that Parslett blackmailed the murderer?" asked Purdie.
