Glevitch is a gossip monger and monstrous woman....... inside and out. She is described as wearing unnaturally-colored make-up and a dress that looks like a garbage bag. She is a cruel and unfeeling woman.
A Map of the World
Glevich is characterized as a negative hero, although she is cold-blooded and prudent. I believe that it is worth saying about the positive side of such a nature as hers. For example, people like her have great success in gambling. I am sure that having played at casino, people like her would definitely be able to increase several times the huge bonus that the casino will provide!
