Óliver Espinosa Sorensen (Barcelona, 1985) holds a degree in Law from the University of Valencia. After working for some of the most prominent law firms and consulting companies in Spain, as well as for the Ministry of Economy, he transitioned into the hospitality sector.

In La librera y el ladrón, he draws on his professional experience to explore the little-known and fascinating world of book thieves, collectors, and bibliophiles, as well as a black market for major cultural works that is far darker than we might imagine.
