On May 18, 2013, in the final seconds of “Name of the Doctor” at the end of the seventh series, something pretty extraordinary happened: We were introduced to an incarnation of the Doctor that we’d never met nor heard of before. Six months later in“Night of the Doctor” we saw how this extra incarnation came to be, and a week after that in the 50th anniversary episode “Day of the Doctor” we watched this incarnation interacting with his Tenth and Eleventh selves (or would that now be Eleventh and Twelfth?) in the final adventure of his life before regenerating into the Ninth Doctor. But what about all the stuff in between? We know that this incarnation fought for a pretty long time in the Time War, since we see him in the form of a fairly young John Hurt in “Night” and far older in “Day.” Now, thanks to Big Finish Productions, we get to hear the War Doctor in action, embroiled in the Time War, in three brand-new linked stories collectively called Only the Monstrous.
