Trock and Shadow walk warily under the bridge by the tenement where Garth lives with his old father, Esdras, and his fifteen-year-old sister, Miriamne. Trock is just released from prison, where he served a sentence for his part in a murder for which Romagna was electrocuted. Judge Gaunt, who presided over the trial when Romagna was convicted, is said to be mad and to be roaming the country telling people that the trial was unfair. A college professor also begins an investigation of the old murder trial. Trock comes to the tenement district to see Garth, who witnessed the murder that Trock really committed. Garth did not testify at the trial, and Trock wants to warn him never to tell what he saw.
Trock threatens to kill Garth if he talks. Miriamne knows nothing about her brother’s part in this crime, but after she hears Trock threaten her brother, she questions him and learns a little about the killing.

Shadow, however, wants no part in killing the judge. As he leaves, Trock sends two henchmen after Shadow to kill him. Mio sees the shooting. Feeling that he came to the right place to learn the truth of the old killing, he waits.
In Esdras’s room the judge awakens, refreshed and normal once more. Realizing where he is and what he did, the judge asks Garth and Esdras to say nothing of his mad claims that Romagna’s trial was unfair. The judge does not want the case to be reopened any more than does Trock. Esdras offers to guide Judge Gaunt partway back to his home.
