Within two minutes after his arrival San Giacinto heard the bolt of the heavy lock run back in the socket and the surgeon entered the mortuary chamber. San Giacinto had nearly finished his cigar and was growing impatient, but the doctor made many apologies for his long absence.

"An unexpected relapse in a dangerous case, Signor Marchese," he said in explanation. "What would you have? We doctors are at the mercy of nature! Pray forgive my neglect, but I could send no one, as you did not wish to be seen. I locked the door, so that nobody might find you here. Pray come with me, and you shall see the young lady at once."

"By all means," replied San Giacinto. "Dead men are poor company, and I am in a hurry."

The surgeon led the way to the accident ward and introduced his companion to a small clean room in which a shaded lamp was burning. A Sister of Mercy stood by the white bed, upon which lay a young girl, stretched out at her full length.

"You are too late," said the nun very quietly. "She is dead, poor child."

San Giacinto uttered a deep exclamation of horror and was at the bedside even before the surgeon. He lifted the fair young creature in his arms and stared at the cold face, holding it to the light. Then with a loud cry of astonishment he laid down his burden.

"It is not she, Signor Professore," he said. "I must apologise for the trouble I have given you. Pray accept my best thanks. There is a resemblance, but it is not she."

The doctor was somewhat relieved to find himself freed from the responsibility which, as San Giacinto had told him, involved the honour of one of the greatest families in Rome. Before speaking, he satisfied himself that the young woman was really dead.

"Death often makes faces look alike which have no resemblance to each other in life," he remarked as he turned away. Then they both left the room, followed at a little distance by the sister who was going to summon the bearers to carry away her late charge.

As the two men descended the steps, the sound of loud voices in altercation reached their ears, and as they emerged into the vestibule, they saw old Prince Saracinesca flourishing his stick in dangerous proximity to the head of the porter. The latter had retreated until he stood with his back against the wall.
