Tromben made his debut in literature in 2003, when he won the El Mercurio Book Magazine contest with his first novel, Poderes Fácticos, a police novel based on a real event: the double homicide of a painter and his partner that occurred in April 1973 in an apartment on Rosal Street.

[5] After La Casa de Electra (2010) —a spy thriller set during World War II with a woman as the protagonist—, in 2015, Tromben published Huáscar, a historical novel that describes the capture of the legendary Peruvian monitor.

The same year he released the novel Crónicas secretas de la economía chilena (Secret chronicle of the Chilean economy), which analyzes the privatization of state companies from 1974 to 1994,[7][8][9] as well as the origin of Sebastián Piñera's fortune.

The work has been on the list of best sellers and was selected as one of the best books of the year by a group of ten critics and cultural journalists.

The same year, he also published La Señora de Dolor, a remake of Karma, which, in Tromben's words, 'is not a 2.0 version of that book, but another novel', because 'they are the same characters, but located in a parallel universe, similar, but not identical'.
