Jonathan finds a chemist that is prepared to work overnight on the infusion, after a personal check backed by a phone call to the Cavendish family bank. You agree to retrieve the finished product tomorrow morning
Assuming you don't mind making the 1 Credit Rating spend required.
George finds no mention of Soran, but does find an article in Scientific American that mentions Zoran Trifkovitch, his real name according to Joseph Deville's diary. It confirms the details of his dismissal from Prague university that you already know, but there is also a photo of the man. As described in the journal, he is bald, and his coarse, greasy skin is evident even in the faded black-and-white newsprint. You cannot tell with any certainty whether Soran's corpse was the one you found in the cellar, however.
Meanwhile, Percival informs himself thoroughly about Bermuda. There is little on a connection to the occult, although he does find several books about the Hiatian religion know as voodoo that can be found throughout the Carribean, and even perhaps in Bermuda too.
No need for a spend from either of you. Percival, assume you have a wikipedia-level background knowledge of Bermuda http://en.wikipedia.org/wiki/Bermuda. See also http://en.wikipedia.org/wiki/Smoot-Hawley_Tariff_Act. BTW, the concept of the Bermuda Triangle did not originate until the 1950s.
You all meet back at around seven o'clock in the hotel to compare notes.
Aside from collecting the purgative, let me know if you have any special plans for Sunday.
