The Mysterious Transformation

Christian Fergrey's marriage turned into a nightmare: so sensitive and attentive before the wedding, after pronouncing the wedding vows, her husband transformed into a tyrant. For a whole year, he poisoned her life and kept her away from friends and... family. One early morning, her sisters show up at the couple's home uninvited to find out why Christian hasn't even responded to their letters.
 
That same morning, they together discover Richard Fergrey dead in his office. However, the astonishing day had just begun, and that morning, left cold and lifeless on the bed in the bedroom, the seemingly dead husband reappears that very evening, alive and well. And he has changed beyond recognition again: friendly with his wife, gentle and caring – he treats her even better than before the wedding.
 
What changes have happened to him? And could it really all have seemed to them that he was dead?
