There's a show with Nathan Fillion called "Castle."  Apparently it's been on the air for several years.  I have NO IDEA what this show is about.  And I probably never will.  

Could it be a romantic comedy?  Is he a spy?  That graphic of the pen kind of looks like it has a pool of blood on the bottom, so maybe it's a dark comedy?  And why is the woman trying to "shush" him?  He seems to be wearing nice clothes, so maybe he's a professional writer and it's like Murder She Wrote.  

This feels like that game show from Saturday Night Live which asks:  What is Burn Notice?  And no one really knows...
