"No fear, dad. I don't forget the biz."

"Well, well; just wait till I've gone through the letters, and we'll see what we can do. We'll see. Ha! this reads well. I like this. Ben, we're in luck this morning. In luck, my boy!"

Mr. Benjamin abandoned his negligent attitude, and, drawing close to his father, peered over his shoulder. The letter which lay upon the desk was not a long one, but it was to the point.

"Thurwell Court,
"Thursday.

"Dear Sirs,

"I am recommended to consult your firm on a matter which requires the services of a skilled detective and the utmost secrecy. I am coming to London to-morrow, and will call at your office at about half-past ten. Please arrange to be in at that time.

"Yours truly,
"Helen Thurwell.

"To Messrs. Levy & Son,
"Private Agents,
—— Street, Strand, London."

Mr. Levy, senior, drew his hand meditatively down the lower part of his face once or twice, and looked up at his son.

"Something in it, I think, Benjamin, eh? Thurwell Court! Coat of Arms! Lady signs herself Miss Thurwell! Money there, eh?"
