Strange things were going on at Underhill, the Hutter family's country estate. One of the weekend guests blamed it on malevolent spirits, accidently unleashed by Florence Hutter Mason's fiddling with a Ouija board. Gamadge agreed the ominous messages typed into the manuscript copy of Florrie's novel were evil, but he knew they weren't put there by a spectral hand. And he feared that soemwhere between the formal gardens outside and the servants' quarters atop the stately mansion, murder was about to happen...because while ghosts don't kill, humans driven by passion, spite, or greed all too often do.
