I took a deep breath and continued to the part that I knew would be the hardest for them to understand. “Also, I found a document that says the goddess Hecate—the exact same goddess that altar is dressed for—gave the power of immunity to Medea, and her children inherited that power from her. It’s been passed down to everyone in her line. Now I have it, but—” I stopped short.

“ ‘But’ what?” Mom asked.

I gripped my hands together in front of me. “Circe and Selene were keeping a plant called the Absyrtus Heart. Absyrtus was Medea’s brother and he was murdered. Dismembered. Medea kept the six pieces of his body buried in her garden. The pieces seeded a plant that isn’t like any other plant in existence—the Absyrtus Heart, and there’s one right out there in my garden. The Colchis family has been running this apothecary and protecting the Heart, but I think Selene was trying to keep me from having anything to do with this place.” If it hadn’t been for Circe I never would have known any of it. That was a detail that still made no sense if she and Selene were as close as everyone else made it seem.

“Someone was after the Heart,” I continued. “It has some very special properties. It’s why . . .” I hesitated. The tendrils of everything I had learned twisted together like the vines in the Poison Garden—inescapable and deadly. The people who’d come after me wanted the Heart. Maybe someone had always been after it, killing off members of the Colchis family to try and get to it. A piece of the Heart had made Marie immortal, and clearly, somebody wanted that power for themselves, wanted it enough to kill for it. Everything I’d learned pointed to one conclusion. “I think that’s why Selene was murdered.”

Mom blinked, then put her hand on her chest. “Briseis, are you serious? Who told you that?”

“The medical examiner,” I said.

“I thought she was sick,” Mo said. “That’s what the agency told us.”

“There’s been some issues with record keeping,” I said. I felt like I was lying and telling the truth at the same time. The issue was that Lou had a job to do in Rhinebeck and it was inextricably linked with trying to keep the Colchis family secrets intact.

An alarm went off on Mo’s phone. She sighed. “I’m supposed to go into the shop and touch base with Jake. I need to do the bank deposit, too, but it can wait.”

“You can go ahead and go, Mo,” I said. “It’s okay.”

“Seems very not okay, Briseis,” she said.

“We need that deposit to get put in the bank,” Mom said. “I don’t want you to go, babe, but I kind of need you to.”

Mo sighed and pinched the bridge of her nose. “I know. I know.”
