While Artie accepted the woman’s hand and shook it, Veronica continued to scrutinize their hostess. Mrs. Eden’s face appeared harder, less fleshy, and more heavily made up than the day before. She also seemed stronger, certainly no longer an invalid.

Veronica relied on her instincts in such situations, and her instincts were telling her that the woman was an impostor. This Mrs. Eden was not the Mrs. Eden she met in this house yesterday.

I chuckled at the melodrama of it. A second Mrs. Eden—as I recalled it, a cousin impersonating the real Mrs. Eden, who was imprisoned somewhere in the house.

Out of nowhere my tired brain connected disparate pieces of information, and I knew who the killer was.

THIRTY-SEVEN

Mrs. Cartwright really wasn’t Mrs. Cartwright.

My solution to the murder was nuts.

Wasn’t it?

If Mrs. Cartwright wasn’t Mrs. Cartwright, then who was she?

Eugene Marter. Had to be.

I realized I hadn’t seen him and his grandmother in the same place at the same time. Had only seen him once, as a matter of fact.

If Eugene was really impersonating his grandmother, then where was the real woman? Was she even still living?

There was an easy way to check that. The Social Security death index.

I slipped on my shoes and hurried downstairs to where I had left my laptop on the kitchen table. As soon as it was ready, I opened the browser and entered a website address. I knew the fastest way to gain access to the information was via a genealogy service to which I subscribed. I input my search terms, Mrs. Cartwright’s name, figuring there couldn’t be that many other women with her name in the index.

There was no listing at all for Electra Barnes Cartwright. I tried Electra Cartwright. No hits. Electra Barnes returned several, but I could tell by the dates that none of them was the correct person.

I leaned back in my chair and considered the possibilities.

The fact that I couldn’t find her in the death index didn’t mean that she was still alive. That thought chilled me. Had they killed her and buried her in the backyard?

Nasty.

Maybe she was alive but mentally incapacitated. No longer able to write or make competent decisions about her books.

That would be tragic, but an alternative preferable to my first thought.

Diesel startled me by meowing loudly beside me. I was so absorbed in my speculations that I had forgotten all about him.

“I’m okay, boy.” I rubbed his head. “Thinking hard, that’s all. Nothing to worry over.”

He warbled a couple of times before he settled down on the floor beside my chair.

How would Kanesha react if I shared this theory with her?

She would demand proof; that’s how she would react.
