A Shadow of Doubt
Madam Ezmeralda Holomek
This Romanian Gypsy woman hasn't been seen in some time, though this could be simply because of her nomadic lifestyle.
A skilled fortune teller, Esmeralda has been known to commune with the dead. Successfully hiding out through the Nazi occupation of France, she only survived because of the heroic actions of Lennore Williams.
Shortly after the war though, she disappeared, likely fleeing the country.
