The perfect scheme of a classic detective story: guests gather in the house, a luxurious reception awaits them - wonderful music and delicious dishes - and then... a murder occurs. There is no doubt: everyone who was in the house had a motive for the murder. This means that anyone could have committed a crime... The murdered man knew too much. The sinful passion of a true Spaniard, the wife of one of the invitees... The fatal mistake of her husband, which led to the tragedy... The carefully hidden attraction of their respectable friend to very young boys... What secret was the murdered man going to reveal? And who committed a crime so that the truth would never come to the surface?..
