"What's our young friend after?" he asked, good-humouredly. "What's his game?"

"Hanged if I know, doctor!" said Ayscough, shaking his head. "He's got some notion in his head. Are you satisfied, Mr. Rubinstein?"

Melky was making for the door.

"Ain't I just said so?" he answered. "You come along of me, Mr. Ayscough, and let's be getting about our business. Now, look here!" he said, taking the detective's arm when they had left the house. "We're going to take a look at them Chinks. I've got it into my head that they've something to do with this affair—and I'm going to see 'em, and to ask 'em a question or two. And—you're coming with me!"

"I say, you know!" remarked Ayscough. "They're respectable gentlemen—even if they are foreigners. Better be careful—we don't know anything against 'em."

"Never you fear!" said Melky. "I'll beat 'em all right. Ain't I got a good excuse, Mr. Ayscough? Just to ask a civil question. Begging their pardons for intrusion, but since the lamented death of Mr. Daniel Multenius, me and Miss Zillah Wildrose has come into his bit of property, and does the two gentlemen desire to continue their tenancy, and is there anything we can do to make 'em comfortable—see? Oh, I'll talk to 'em all right!"

"What're you getting at, all the same?" asked the detective. "Give it a title!"

Melky squeezed his companion's arm.

"I want to see 'em," he whispered. "That's one thing. And I want to find out how that last cheque of theirs got into our back-parlour! Was it sent by post—or was it delivered by hand? And if by hand—who delivered it?"

"You're a cute 'un, you are!" observed Ayscough. "You'd better join us."
