“Tell her I'm sorry I sold the diamond, eh?" Sammy said. "I broke my promise. When she disappeared in Alaska... ah, so long ago, I finally used that diamond, moved to Texas as I always dreamed. I started my machine shop. Started my family! It was a good life, but Haze; was right. The diamond came with a curse. I never saw her again."

"Oh, Sammy," Hazel said. "No, a curse didn't keep me away. I wanted to come back. I died!"

The old man didn't seem to hear. He smiled down at the baby, and kissed him on the head. "I give you my blessing, Leo. First male great-grandchild! I have a feeling you are special, like Hazel was. You are more than a regular baby, eh? You will carry on for me. You will see her someday. Tell her hello for me.”
