"Mental excitement," said Mr. Sheldon, somewhat hastily; "Charlotte is nervous to an extreme degree, and your sudden arrival was calculated to shake her nerves."

"Undoubtedly," rejoined the doctor; "and it is unquestionable that such a dilatation of the pupil might, under certain circumstances, be occasioned by mental excitement. I am sorry to find that our patient's attacks of dizziness—"

"Which are purely the effect of fancy," interjected Mr. Sheldon.

"Which are no doubt, in some measure, attributable to a hypochondriacal condition of mind," continued the doctor in his fat voice. "I am sorry to find that this periodical dizziness has been somewhat increased of late. But here again we must look to Dr. Poseidon. Tepid sea-baths, if they can be managed, in the patient's own room; and by-and-by a dip in the waves yonder, may do wonders."

Valentine asked no further questions; and the physician departed in the St. Leonards fly, to turn his excursion to profitable use by calling on two or three dowagers in Warrior Square and Marina, who would doubtless be glad of an unexpected visit from their pet doctor.

"Well, Hawkehurst," said Mr. Sheldon, when the fly had driven away, "I hope you are satisfied now?"

"Satisfied!" cried Valentine; "yes, I am satisfied that your stepdaughter is being murdered!"

"Murdered!" echoed the stockbroker, his voice thick and faint; but
Valentine did not heed the change in it.

"Yes, murdered—sacrificed to the utter incompetence of that old idiot who has just left us."

Philip Sheldon drew a long breath.
