“That’s amazing.” I sat on the bed, and Diesel hopped up beside me. “She’ll be a hundred on her birthday this year, whenever it is.”

“That’s right. I looked her up in Contemporary Authors. She’ll be a hundred in May. How do you remember these things?”

“One of my habits, storing away useless trivia.” I laughed. “There must be some connection between girls’ mystery series and longevity. Both Mildred Wirt Benson and Margaret Sutton lived to be nearly a hundred.”

“I know Benson wrote many of the early Nancy Drew books,” Teresa said. “Who was Margaret Sutton?”

“She wrote the Judy Bolton books.”

“I don’t remember reading those,” Teresa said. “They must not have been around when I first discovered and read books like that.”

Teresa, in her midthirties, was a good fifteen years younger than I, and the Judy Bolton books were out of print by the time she came along. I mentioned this, and she laughed.

“Obviously I’ve missed a good series. You’ll have to tell me more about them later, because you probably know all there is to know about Judy Bolton. Otherwise you wouldn’t be advising us on our National Library Week exhibit.”

I had picked up a fair amount of knowledge over the years about series books, such as Nancy Drew and the Hardy Boys, and I was delighted to put my seemingly arcane knowledge to good use for once.

“Now back to Ms. Cartwright.” Teresa reclaimed my attention. “I started noodling around on the Internet. Came up with the number for an agent named Yancy Thigpen and thought I’d take a chance and call.”

“What did you want from the agent?” I asked. “Unless you suspected that Electra Barnes Cartwright was actually still alive.”

“I thought that was unlikely,” Teresa said. “I was hoping the agent might know of any artifacts or special materials we could use for the exhibit. I never dreamed she would tell me that the author was still living.”

“That is a wonderful surprise.”

“This whole thing is coming together like it’s truly meant to be.” I could picture her bouncing in her chair judging from the enthusiasm bubbling in her voice. “Now for the really big news—not only is she still alive, but Electra Barnes Cartwright lives nearby. How’s that for amazing?”

I felt dazed. “I knew she grew up around Calhoun City”—a small town about a hundred miles south of Athena—“but from what little I remember reading about her, she left the South and settled in Connecticut when she was in her twenties. When did she come back to Mississippi?”

“About twenty years ago. Yancy said Mrs. Cartwright lives quietly out in the country with her widowed daughter and grandson, between here and Mineola. Do you know them? Marcella and Eugene Marter.”
