A BBC Radio 4 full-cast dramatization.

Anton Lesser and Anna Madeley.

"The Iron Hand of Mars sees Roman private eye Falco being dispatched to one of the most hostile parts of the Empire to deliver an iron hand to one of the legions. Germania is cold, wet, dismal and full of dark forests inhabited by bloodthirsty barbarians, but Falco has an even bigger problem to worry about--he has forgotten Helena Justina's birthday, and she is being pursued by the Emperor's son, Titus Caesar. As Falco makes his way through dangerous territory, he encounters the aftermath of a grisly crime, investigates the case of a missing legate, gets into trouble with a centurion, and has a fateful encounter with a Celtic priestess and a giant bull. With the help of his travelling companions, Falco must try to complete his most deadly mission yet."
