Amherst, Mass. may have its “Belle” a.k.a. Emily Dickinson, but if it’s October in Massachusetts, with Halloween just around the corner, Emily takes a back seat to Miz Lizzie. Stand by for a plethora of programs on the sharpest gal in town from the Discovery Channel, PBS and the Travel Channel. Jeffrey Arrowood, an attorney and former police chief will appear on Discovery Channel’s “Ghost Lab,” acting as prosecutor in a trial scenario at 8 p.m. Oct. 28th. The filming was done this past May at the house on Second Street.
