At last, the quiet, post-holiday evenings of January have arrived, and Heartwood Theater Company is on stage in the Poe Theater to fill a few of these evenings, with an engaging, award winning three-character play by Michael Hollinger, “Ghost-Writer.” Actors featured in this absorbing tale include two who are well known to the Midcoast Community, Dixie Weisman of Newcastle and Millie Santiago of West Boothbay, and a newcomer to Heartwood, Dwight Burtis of Thomaston.
