“You have killed him!” she muttered. “Oh, Dio mio , you have killed him!” Then I heard a sudden sharp intake of her breath, and she sprang into the air with a cry of joy. Round and round the room she danced, her hands clapping, her dark eyes gleaming with delighted wonder, and a thousand pretty Italian exclamations pouring from her lips. It was terrible and amazing to see such a woman so convulsed with joy at such a sight. Suddenly she stopped and gazed at us all with a questioning stare.

“But you! You are police, are you not? You have killed Giuseppe Gorgiano. Is it not so?”

“We are police, madam.”

She looked round into the shadows of the room.

“But where, then, is Gennaro?” she asked. “He is my husband, Gennaro Lucca. I am Emilia Lucca, and we are both from New York. Where is Gennaro? He called me this moment from this window, and I ran with all my speed.”
