“There is no need of apprehension on that head, madam,” answered Green. “Speak freely—and without reserve.”

“I have called upon business of great importance to myself, and which may prove most lucrative to you,” continued the lady.

“Before we proceed farther, madam,” said the lawyer, “may I request to be informed who recommended you to me?”

“A client of yours who resides in Pimlico, and with whom I am acquainted,” answered the beautiful woman. “Perhaps you have heard mention made of my name. I was the Countess of Carignano: but I presume that, since my husband’s native land has become a Republic and abolished titles of nobility, I must introduce myself to you as Signora Barthelma.”

“I have heard of you, madam,” responded Green: “and I shall be delighted to number you amongst my clients.”

“It is for this purpose that I have addressed myself to you to-day,” observed Laura. “But I must at once inform you that the object of my visit is scarcely connected with law.”

“If I can serve you, madam——” began Green, who was completely fascinated by her beauty and her manners.

“And serve yourself also?” added Laura: “yes—you can do both! Know, then, that I cherish a rancourous—burning hatred against two individuals—father and son—and that the time has now come for me to wreak my vengeance upon them. The son has just returned from Italy—I saw his arrival mentioned in this morning’s paper; and not another day—not another hour can I rest ere a train be laid that must lead to the explosion of all the happiness they now expect to enjoy.”

“And who are these persons, madam?” asked Green.

“Their name is Hatfield—and they reside at the mansion of the Earl of Ellingham, in Pall Mall,” responded Laura. “I am acquainted with a terrific secret regarding that family—a secret which would make the hair of all England’s proud aristocracy stand on end—a secret, in fine, that now affords me the means of humbling my two mortal enemies in the dust. Will you, sir, become the instrument of my vengeance?—will you perform my bidding in all respects? I know that I ask a great deal—that I am about to involve you in no trifling nor unimportant enterprise—and that the business does not with propriety come within the sphere of your professional avocations. But the recompense shall be most liberal; and I proffer this note for five hundred pounds as an earnest of my intentions in that respect.”
