One Final Mission. There is no time to rest for Eliza D Braun and Wellington Thornhill Books. The man who has haunted and hounded them since the fall of the Maestro—Doctor Henry Jekyll—is now on a killing spree, using bizarre, theatrical murders as a way to taunt their inability to capture him. Of course, Books and Braun know this is a trap, so it falls on the Ministry's Finest to turn the tables on Jekyll and bring him to justice. As Wellington and Eliza pursue both man and monster, the House of Usher continue to push forward with Operation: Ragnarök. Agents Bruce Campbell and Brandon D Hill undertake the challenge of stopping the dark society in their tracks, unraveling a mystery that could plunge the world into chaos, despair, and a noticeable lack of Devon Cream Teas. The Ministry will not let this stand.
