Marcus stepped closer and looked over my shoulder at the words.

I looked toward the back door of the cottage that opened onto the overgrown garden.

“It’s talking about the greenhouse,” I said clearly.

The old glass greenhouse stood past a row of neglected hedges, its ancient panes heavily clouded with dirt and moss.

The narrow side door was fastened with a badly rusted iron lock.
