It's either Ms. Blake or the mystery girl. The killings didn't happened, until the mystery girl got killed. Also, I read somewhere that she is still alive and will be returning later in the season. They did say, that the darach will be revealed later on in the season. If Deucalion offed her, then how can she be alive? This is probably all to kill Deucalion and his gang or something. Also it is not Peter since Jeff let out  that Peter will die.
