_Nina Balatka_ is, on the surface, a love story--not an unusual theme for
Trollope. Romance and courtship were woven throughout all his previous
works, often with two, three, or even more pairs of lovers per novel.
Most of his heroes and heroines, after facing numerous hurdles, often
of their own making, were eventually happily united by the next-to-last
chapter. A few were doomed to disappointment (Johnny Eames never won
the heart of Lily Dale through two of the "Barsetshire" novels), but
marital bliss--or at least the prospect of bliss--was the usual outcome.
Even so, the reader of Trollope soon notices his analytical description
of Victorian courtship and marriage. In the circles of Trollope's
characters, only the wealthy could afford to marry for love; those
without wealth had to marry for money, sometimes with disastrous
consequences. By the time of _Nina_, Trollope's best exploration of
this subject was the marriage between Plantagenet Palliser and Lady
Glencora M'Cluskie, the former a cold fish and the latter a hot-blooded
heiress in love with a penniless scoundrel (_Can You Forgive Her?_
1865). Yet to come was the disastrous marriage of intelligent Lady
Laura Standish to the wealthy but old-maidish Robert Kennedy in _Phineas
Finn_ and its sequel.

But _Nina Balatka_ is different from Trollope's previous novels in four
respects. First, Trollope was accustomed to include in his novels his
own witty editorial comments about various subjects, often paragraphs or
even several pages long. No such comments are found in _Nina_. Second,
the story is set in Prague instead of the British isles. Third, the
hero and heroine are already in love and engaged to one another at
the opening; we are not told any details about their falling in love.
The hero, Anton Trendellsohn is a successful businessman in his mid-
thirties--not the typical Trollopian hero in his early twenties, still
finding himself, and besotted with love. Anton is rather cold as lovers
