We begin this episode in an unusual position: a step ahead of the women of the Bletchley Circle.
A man is in the hospital, his body covered with ugly, blistery chemical burns. He’s expected to die, and when he does his cause of death will be falsified. We know this; our heroines don’t. So we have a few minutes to feel clever or to try piecing things together on our own before the “Circle” closes in on the truth.
Meanwhile, the clock is ticking. Alice Merren declined her opportunity for appeal and her execution date has been set. Only five days remain for the women to determine who really murdered John Richards and why.
