The woman sprang to her feet, with a cry.
"Ferrari! impossible."
"Is his name Ferrari?"
"Yes! No! that is, Mr. Maxwell," she cried, seizing the young man by the lappet of his coat "What do you mean? what do you suspect?"
"I mean that this diamond pin belongs to Ferrari, whom you have just named. I suspect that he murdered Sir Rupert Pethram."
Mrs. Belswin uttered a cry of terror.
"No! no! It cannot be."
"Then let him prove his innocence."
"Prove his innocence?"
"Yes!" said Maxwell, with an air of determination. "I have made up my mind to bring the murderer of Sir Rupert Pethram to justice. Appearances are dead against this man, and I intend to put the matter in the hands of the police."
