When in 1998 the Duke of Feria tried to commit suicide by cutting his wrists, Luis took him to the hospital. In 2011 he recounted in ‘Vanity Fair’: «Then he regretted it. He told me: ‘I’m sorry, I’m sorry’. I answered: ‘Dad, if it’s not for me, it’s for you, because I want you to be here and to be alive.’ He was also the only one to visit him regularly when, shortly after, he was admitted to a psychiatric facility. On August 4, 2001, on the verge of turning 59, he died of an overdose of barbiturates.
