The Witchfinder's Apprentice. Witchfinders, #1

Massachusetts in the Year of the Lord 1695: Matthew Goodson, eighteen years of age, is apprenticed to a team of experienced witchfinders, who travel from village to village and town to town to uncover witchcraft, examine the evidence, interrogate suspects and stamp out evil. When a wave of mysterious illnesses and deaths hits the town of Redemption, the witchfinders are called in and quickly arrest a suspect, a teenaged girl named Grace Pankhurst. Matthew has long been having his doubts about the witchfinders and the righteousness of their mission.
The interrogation of Grace brings those doubts to a flashpoint. But is Grace truly innocent or has Matthew fallen under the spell of a comely witch? This is a historical horror story of 5500 words or approximately 20 print pages by two-time Hugo finalist Cora Buhlert.
