Welcome to the year 457 million BCE and another episode of "The Scales of Justice," the courtroom drama adventures of Balthasar Q. Esterhazy, Trilobite-at-Law. Esterhazy fights to prosecute the worst bottom-feeders in the Paleo-Tethys Ocean and put them behind bars of iron-hard coral for good—and does so one last time. In today's sprawling episode—too big for one episodic segment but just a bit too small for a full radio play—Esterhazy, Lapworth and Judge Hydra contend with cold seas as a result of the Ordovician Period sticking around a little too long. A menace from the future—giant volcanic tubeworms—will need to be countered by something equally destructive from the Earth's past. But what will that be?
