Of course, you know that there is NO Mrs. Frankenstein, well, sort of.
The mystery woman is none other than--

MRS. SHELLY!
or,

Mary Wollstonecraft Shelly, to be exact,
the author of the great novel,
FRANKENSTEIN.

So, you must also know that Mary Shelly (as she came to be known)
wrote the novel in the early 19th Century.
Conceived in 1816, the novel was published in its first edition in 1818
and published in a second, somewhat revised edition in 1831.
It has, since that time, been a timeless classic, and well worth a read.

There are some wonderful Internet sites where you can find out more about Mary Shelly, Ingolstadt, and "Mary Shelley's Frankenstein," the 1990's movie. These are listed at the end of the game, Time Travel Clyde, on the credits page. When you finish the game (assuming you ever manage to get free of the Time Rings), be sure and check them out!
