The Mentalist of one of my favourite TV Series. There are 7 season which are available online. I watched it on Amazon Prime. Simon Baker(Patrick Jane) has a way of his own in solving crimes. He loves playing mind games and that makes him intriguing. With each season you’ll fall in love with him.
I don’t want to be a spoiler, so won’t be sharing the story. But I would recommend you to watch this series as a must.
