Missir's wartime experience informed his only novel, the 1937 Fata Moartă, which proved a resounding critical and commercial success.

(Missir had an abiding love for the town and the entire north of Moldavia; like his father, he enjoyed spending his free hours working the nearby vineyard they had inherited from a princely official.)

[1][2] After the war, he resumed the practice of law, also entering politics in the factions led by fellow townsman Nicolae Iorga.

In a later interview, Missir noted that he began the book as a protest against those who objected to providing discounts on the Căile Ferate Române railway for decorated war veterans.

He also benefited from what Vladimir Streinu termed a "literary instinct": the action is set amidst the events it details, mainly in the present tense, and moves with great speed.

The battle scenes follow in a quick succession of short phrases enriched by an eye for detail that is unsparing of the narrator, of his comrades and of the reader in its honesty.

The protagonist, an officer, is given to frequent introspection; the book conveys the fear, the incompetence of the commanders and of those behind the front, the progressive degradation of spirit.

[6] Although Missir published no other novels, he did write a manuscript about the Soviet occupation of Bessarabia and Northern Bukovina; this appears lost.
