Hewitt laughed. "Perhaps it is," he said. "Now, as to the man who sent you with the bag. Was it an old bag?"

"Bran' cracklin' new—a brown leather bag."

"Locked?"

"That I niver thried, sor. It was not my consarn."

"True. Now, as to this Mr. W. himself." Hewitt had been rummaging for some few minutes in a portfolio, and finally produced a photograph, and held it before the Irishman's eye. "Is that like him?" he asked.

"Shure it's the man himself! Is he a friend av yours, sor?"

"No, he's not exactly a friend of mine," Hewitt answered, with a grim chuckle. "I fancy he's one of that very respectable family you heard about at Mr. Hollams'. Come along with me now to Chelsea, and see if you can point out that house in Gold Street. I'll send for a cab."

He made for the outer office, and I went with him.

"What is all this, Hewitt?" I asked. "A gang of thieves with stolen property?"

Hewitt looked in my face and replied: "It's the Quinton ruby!"
