“I can't tell you what I don't know,” said Mr Brown, impelled by curiosity to try to see whether the note between Randall's long fingers was for ten pounds or only five.

“Perhaps I ought to tell you that I am not a policeman,” sighed Randall. “Though I believe one of the plainclothes fraternity is wandering about outside.”

“Think I don't know?” said Mr Brown scornfully. “I could tell a busy half a mile off.” It dawned on him that his visitor also appeared to possess this useful faculty, and he added with more respect in his voice: “You'd better clear off out of this. I don't want no more trouble than what I've got already, and I tell you straight Mr Hyde ain't here, nor he hasn't been near the place for ten days.”

“In view of the gentleman outside that hardly surprises me,” said Randall. “But I feel sure you could direct me to him—for a consideration.”

“Well, I couldn't,” said Mr Brown curtly. “What do you want with him?”

Randall's slow smile curled his lips. “Do Hyde's visitors usually confide in you?” he asked.

There was a slight pause. Mr Brown stared frowningly at him, and after a moment said: “Look here, I don't know no more than you do where Mr Hyde is, and what's more I've had enough of him and his games! You clear off out of this before that busy outside starts smelling round after you, that's my advice!”

Randall regarded him thoughtfully. “Perhaps,” he said, “if I were to leave a letter for him in your charge it would be delivered? Oh, for a consideration, of course!”

Mr Brown cast a hasty glance towards the door of the shop, and said loudly: “Well, it wouldn't then, because I don't know where to deliver it! What do you want? What's your blooming hurry to get hold of Mr Hyde?”

“Oh, I don't think it's necessary for you to know that,” said Randall. “I just have business with him—ah, somewhat, important business. I wonder if you could use ten pounds?”
