Follow Victor Kral’s unfinished investigation through Prague and uncover the mystery of the Thirteenth Sign. His manuscripts lead you through the Old Town, where clocks, statues, Hebrew symbols, medieval towers and old house signs hide pieces of a larger pattern.
Observe real details around you, solve Victor’s puzzles and discover what he failed to understand in 1681: what — or who — is the Thirteenth Sign?
