Sitting on the Edge of the Bed A Dark Psychological Thriller of Obsession and Betrayal She trusted her with everything. That was her first mistake. Marta lies in a hospital bed, suspended between life and death. Alicia sits beside her - waiting, remembering, confessing. Because the truth about what happened that night is far more dangerous than anyone suspects. And time is running out. Two women. One secret. A lifetime of lies. Marta Suárez was brilliant, untouchable, and dangerously charismatic - a master manipulator who always stayed one step ahead of everyone. Including the police. Including Alicia. When a mysterious car accident leaves Marta in a coma, a clock begins to tick. A year earlier, Marta signed a document entrusting Alicia with an irreversible decision - one that could expose everything they built together. As Alicia sits on the edge of Marta's hospital bed, she begins to unravel the truth. Their past resurfaces in fragments: university schemes, psychological games, stolen identities, political corruption, hidden money, and a dangerous man with a tattoo and a black Tiguan. But this is not just a story about crime. It is a confession. A story of obsession. Of loyalty turned toxic. Of love distorted by ambition. Of how far one woman will go to protect the only person she has ever truly loved. And of the moment when control slips away.
