Richard Castle is a man who loves mysteries. He’s made them his life’s work, after all. But the one mystery that Castle wants solved more than anything else is his own.

After he was found at sea with a bad case of amnesia in Castle‘s season-seven premiere, the mystery of what happened to him in the two months after his car accident is still very much alive. And in an exclusive clip from next week’s episode, titled “Montreal,” we get a glimpse at just how far Castle’s willing to go to find answers. When an interview gets a little too personal, Castle asks for his fans help in solving his case.
