Complete story — includes the ending
Mrs. Frederic and Steve are in the Vatican with Brother Adrian, looking for a possibility to free Artie from the effects of the astrolabe. While doing so, they find a precise description of what the Astrolabe is doing to him: It has split Artie's personality, and the dark side of this personality slowly erases the good side. Meanwhile, at the Warehouse, the team finds H. G Wells' research on the dagger from Artie's vision. They find out that Artie wants to use the blade to break the Chinese orchid container, which would release a deadly disease - the English Sweating sickness - into the world. While Pete and Myka go to Prague to retrieve the dagger, Steve and Claudia go to Berlin looking for the orchid.
Meanwhile, Mrs. Frederic goes to the Budapest Airport, and she finds the security guards tied up and gagged, and Artie is gone. Artie forestalls Pete and Myka by using Isaac C. Parker 's noose and goes after the orchid himself, not in Berlin. The team rushes after Artie to foil his plans and bring him to his senses but fails. Artie releases the orchid, at which point his vision of Claudia stabbing Artie with the dagger comes true. Artifacts: The Chinese Orchid, Isaac C. Parker 's noose, Yogiraj Bengali 's Snake Basket, Barometer from the USS Eldridge, Supersonic Cymbals, Francesco Borgia 's Dagger, Glassblowing Tube
