Before getting married, my mom forced me to put my two-million-dollar apartment in her name. She told me: “Don’t say anything to Jason or his family.” I thought she was crazy. Until my mother-in-law took the microphone in front of 200 guests and announced that my place on the Upper East Side would be her retirement home.

My hands froze. “Who?”

Mr. Henderson took a deep breath. “A young woman and two men. They said they were sent by Mrs. Eleanor.”
