Grand Hotel - Season 1 - Eps 3: The Golden Knife
Julio is closer than ever to find out who murdered his sister and the main suspect is none other than Diego, Alicia's fiancé. Without proof to prove it, Julio will only have one possible path for his investigation; find the author of the anonymous Diego, the only person who can shed light on the death of Cristina. However, in parallel, Detective Ayala is following another clue: that of the weapon with which Jimena's murder was committed. The famous gold knife that appears in Javier's room, which was also the last person with whom the prostitute was killed. All indications point to the young Alarcón.
