About the previous episode: Yoomurjak’s Ring
The story begins when Jonathan Hunt, a journalist from New York, arrives in the city of Eger in Hungary for a break. He has local ancestry and speaks the language, but this is not the only motive for his visit. In the heritage of his great-grandfather, the globetrotter professor Samuel Hunt (known from the Agon series), he found two letters dated back in 1898. The letters were from a somewhat lunatic Hungarian scientist about a time machine he claimed to be working on. The references point to Eger, and Jonathan wants to find out what happened to the man and his preposterous invention. But soon he realizes that someone is desperately trying to stop him…
