"And when I further tell you," continued Jack, "that, after yourself and my mother, I am the next heir to the estates of my grandfather, Sir Montacute Trenchard, you will perhaps own that my caution is sufficiently disinterested."

"Could I credit your wild story, I might do so," returned Thames, with a look of perplexity.

"Here are Jonathan Wild's written instructions to Quilt Arnold," rejoined Sheppard, producing the pocket-book he had found in the janizary's clothes. "This letter will vouch for me that a communication has taken place between your enemies."

Thames glanced at the despatch, and, after a moment's reflection, inquired, "In what way is the attempt upon my life to be made?"

"That I couldn't ascertain," replied Jack; "but I advise you to be upon your guard. For aught I know, they may be in the neighbourhood at this moment."

"Here!" ejaculated Wood, with a look of alarm. "Oh lord! I hope not."

"This I do know," continued Jack,—"Jonathan Wild superintends the attack."

"Jonathan Wild!" repeated the carpenter, trembling. "Then it's all over with us. Oh dear!—how sorry I am I ever left Wych Street. We may be all murdered in this unprotected place, and nobody be the wiser."

"There's some one in the garden at this moment," cried Jack; "I saw a face at the window."

"Where—where?" cried Thames.
